Abstract
The invention provides a preparation method of glass fiber reinforced nylon. The preparation method of the glass fiber reinforced nylon comprises the following steps: 1) preparing a PA66 graft, namely mixing PA66, MAH (maleic anhydride) and other auxiliaries in a high-speed mixer, and then extruding and granulating by virtue of a double-screw extruder, so that PA66-g-MAH is obtained; 2) preparing glass fiber reinforced PA66, namely adding the PA66, the PA66-g-MAH and other auxiliaries into the high-speed mixer and mixing, adding quantitative alkali-free glass fibers, blending with molten mixed material, extruding, drawing, cooling, and carrying out sized dicing, so that the glass fiber reinforced nylon aggregates are obtained. The preparation method of the glass fiber reinforced nylon has the technical effects that the prepared glass fiber reinforced nylon has the original good properties of the PA66 and also is greatly improved in strength, hardness, rigidity and heat resistance.
Description
Technical field
The present invention relates to a kind of preparation method of glass fiber enhanced nylon, belong to modified engineered plastic technical field.
Background technology
Modified engineered plastic, refers on the basis of general-purpose plastics and engineering plastics, through method processing such as filling, blend, enhancings, has improved the plastic products of the performance of the aspects such as anti-flammability, intensity, impact resistance, toughness. Common plastics often have it self characteristic and defect, and modified plastics changes character to plastics exactly, and basic technology comprises: 1, strengthen: by glass fibre etc. with plastic blend to increase the mechanical strength of plastics. 2, fill: by the fillers such as mineral and plastic blend, the character such as shrinkage factor, hardness, intensity of plastics is changed. 3, toughness reinforcing: by add flexibilizer blend to improve the toughness of plastics, the product after toughening modifying: rail pad to common plastics. 4, fire-retardant: add fire retardant to common plastics resin the inside, can make plastics have flame-retarding characteristic, fire retardant can be a kind of compound system of or several fire retardants, as bromine+antimony system, phosphorus system, nitrogen system, silicon system, and other inorganic fire-retarded systems. 5, cold-resistant: to increase plastics intensity and toughness at low temperatures, the general intrinsic at low temperatures black brittleness of plastics, makes to apply in low temperature environment limited, need to add some low temperature resistant flexibilizer and change plastics fragility at low temperatures, the plastics such as such as bumper, General Requirements is cold-resistant.
Nylon (PA) the 66th, a kind of engineering plastics of function admirable, there is higher intensity and good heat resistance, corrosion resistance, wearability and flow processability, be widely used at aspects such as automobile, electronics, electrical equipment, mechanical part, transportation equipments. And PA66 as structural material the application on textile equipment had higher requirement in the aspects such as its intensity, wearability.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art part, a kind of preparation method of glass fiber enhanced nylon is provided.
The preparation method of glass fiber enhanced nylon of the present invention, comprises the steps:
1) preparation of PA66 graft
After PA66, MAH and other auxiliary agents are mixed in high-speed mixer, use double screw extruder extruding pelletization, make PA66-g-MAH;
2) preparation of glass fiber reinforced PA66
PA66 is added in high-speed mixer and is mixed in proportion with PA66-g-MAH and other auxiliary agents, add quantitative alkali-free glass fibre, with the mixed material blend of fusing, extrude, traction, cooling, pelletizing, make glass fiber enhanced nylon pellet.
Described auxiliary agent is selected from one or more in crosslinking agent, coupling agent, flexibilizer, filler, reinforcing agent, lubricant, antioxidant, age resister, dispersant, stabilizing agent.
The present invention has following technique effect: glass fibre reinforced nylon prepared by the present invention is except having the original premium properties of PA66, and its intensity, hardness, rigidity, heat resistance etc. all improve greatly.
