Description
Technical field
The present invention relates to the technical fields of thermoset glass composite material in high molecular material, specially a kind of
The unsaturated polyester resin compositions and its tubular molding compound of non-alkali metal system thickening.
Background technology
With the rapid development of domestic electric utility technology, the bakelite and ceramics largely used in case for circuit breaker in the past
The shortcomings that waiting traditional materials increasingly emerges, such as the former mechanical strength, electric durability energy, dimensional stability index have been unable to meet
The product requirement of continuous improvement；And although the latter's chemical property is stablized, and has the insoluble problems such as hard and crisp, easy fragmentation.
Therefore both gradually by of new generation, thermosetting plastics --- tubular molding compound substitutes, this is one kind mainly by unsaturated polyester (UP)
The prepreg that resin, filler and short glass fiber and various additives are adequately mixed.
However, in order to ensure that this key index of its molded product mechanical strength meets the high rule of breaker of plastic casing material
Lattice, the moulding compound of unsaturated polyester resin base, which just must largely add in the longer short glass fiber of fiber, to be enhanced, but with
The increase of content of glass fiber and the raising of length, inorganic filler and glass fibre in itself will necessarily by the effect of resin infiltration
Tend to deteriorate, the overall viscosity of additional material is relatively low so that moulding compound Solid-Liquid Separation easily occurs when heating pressurized flow
Tendency, the solid phase being separated wraps due to lacking resin, and molding will show as the white of many different sizes when finishing
Piebald is distributed in the surface of molded product in a jumble, especially more intensive in the relatively thin position of wall thickness and especially apparent.For this purpose, state
Inside and outside numerous enterprises unit and academic institution have carried out numerous studies with regard to the problem and have achieved comparable achievement.
Patent US4263198 discloses a kind of chemical thickening agent suitable for unsaturated polyester resin based composites,
Alkali metal oxide of the specific ingredient for II A races in the periodic table of elements.The application of this kind of chemical thickening agent become industry compared with
Classical solution, such as in the unsaturated polyester resin of tubular molding compound in advance
1st, in terms of the quality control of unsaturated polyester resin：The number-average molecular weight and acid value of unsaturated polyester resin, all can
Viscosity ascending curve in densification is seriously affected, eventually affects resin or even the average viscosity of tubular molding compound.
And the manufacturer for much producing tubular molding compound does not produce resin in itself, therefore do not have corresponding detection means and specification index adds
With control.
2nd, the use aspect of thickener：The alkali metal oxide used as thickener the easy moisture absorption mostly, and thickened
Journey has extremely strict requirements for the moisture in system, such as can make increasing using during magnesia 0.1%~0.8% minor amount of water
Thick acceleration, but thickening effect is also poorer than anhydrous instead during more than 1%, may cause thickening failure, resin residual viscous more than 1.5%
And material is touched with one's hand.Therefore alkali metal oxide and inactive resin carrier can be used in mixed way to reduce its moisture absorption by some manufacturers
Property, but this method can greatly improve the finely dispersed difficulty of thickener, and the thickener of paste needs additional high-speed stirred pre-
It mixes and comes that guarantee system is uniform, this is a kind of common resin container and the inefficient mixed process of kneader, it is necessary to add additional
Equipment complete, and additional manpower is spent to be managed.
3rd, in terms of the process management and control of later stage curing：Influence resin thickening various factors in, temperature be it is most important because
Element --- it is too low to reach thickening effect；It is excessively high, it can seriously reduce tubular molding compound final mobility and processability.Often
The alkali metal oxide thickening unsaturated polyester resin moulding compound of rule, needs 30~50 DEG C of environment temperature to carry out post curing, short
Palpus a few hours, length then up to a couple of days, at least more than the several times of mixed process used time, just need additionally to build baking in practical volume production
Room is realized, can not only be occupied considerable man power and material, can also substantially be extended manufacture cycle.
Other than alkali metal oxide is used alone and carries out ligand complex thickening,《Fiberglass/composite material》2012
2nd phase《The modified SMC researchs of TDI thickenings》With the 3rd phase of the same year《MDI is modified BMC research researchs》In, there is researcher to carry
It is different the binary such as a kind of alkali metal oxide combination toluene di-isocyanate(TDI) (TDI), methyl diphenylene diisocyanate (MDI) have been gone out
Cyanate esters carry out the new approaches of the netted thickening of interpenetrating, although being thickened compared to traditional alkali metal system, the thickening process
The performance and storage life of tubular molding compound can be improved to a certain extent, but still cannot save the later stage to cure this most
For time-consuming process.And the price of binary isocyanate compound is higher with respect to other raw materials in tubular molding compound, in reality
Cost problem can be further exacerbated by by coming into operation in volume production.
In addition, patent CN200410013422.9 discloses a kind of low pressure SMC thickener and preparation method thereof, and in patent
The technical solution for being applied to production is proposed in CN200510019581.4.According to the technique that above-mentioned patent describes, although
The temperature and time requirement of material later stage curing is effectively reduced, but is needed during the exclusive use of crystallinity unsaturated polyester resin
The dosage of resin total mass fraction 20% is equivalent to, thus obtained sheet molding compound viscosity is very high, mobility and processability have
Limit, molded product is mostly plank simple in structure, can not cope with the complicated product of design.In addition, the core in the thickening
The medium temperature of material is controlled when technique is winding, various raw materials before mixing after temperature change it is larger, it is difficult to mediated in large size
It is realized in machine, must then add in post curing engineering again to complete thickening, therefore the thickened systems are not yet applied to traditional bulk
During moulding compound is manufactured.
Invention content
The purpose of the present invention is：Easily there is Solid-Liquid Separation when heating pressurized flow to solve the problems, such as moulding compound,
And provide unsaturated polyester (UP) composition and tubular molding compound of a kind of non-alkali metal system thickening and preparation method thereof.It also solves simultaneously

Control a series of problems, such as numerous and diverse.
The present invention technical principle be：It is a small amount of modified unsaturated by being mixed into traditional unsaturated polyester resin system
Polyester resin, to play the physics thickening effect different from basic salt and carboxyl coordination complexing.Due to synthesizing modification unsaturation
Terephthalic acid (TPA) containing more high symmetrical structure in the raw material of polyester resin forms terephthalate knot in main chain after polymerization
Structure.The carbonyl that the benzene radicals of the structure align each other with two is connected, in the rigidity for effectively improving linear polymer backbone
While, pass through electron conjugated interaction general between molecule segment so that the modified resin compares general unsaturated polyester (UP) tree
Fat has better room temperature crystallinity.But the synthesis of this modified unsaturated polyester resin, to the dosage of phthalic acid in raw material
There is strict demand, i.e. its mole fraction should account for the 30~80% of polyacid mole summation.When dosage is excessively high, gained is modified insatiable hunger
It is excessively high with the crystallinity of polyester resin, it is difficult to be uniformly dispersed in the composition of unsaturated polyester resin；And when dosage is too low,
The structural symmetry and crystallinity of gained modified unsaturated polyester resin are unable to meet demand, and follow-up thickening is unable to reach expected effect
Fruit.
In the temperature-fall period after tubular molding compound is kneaded, under the action of styrene isoreactivity solvent, uniformly dissipate
