The invention discloses a kind of PVC door-window section bars and preparation method thereof with flame retardant property, are made of following raw materials according：Polyvinyl chloride resin, haloflex, nylon 6, glass fibre, titanium dioxide, calcium carbonate, expanded graphite, 5 15 parts of vermiculite power, main flame retardant, auxiliary flame retardant, compatilizer, toughener and stabilizer.The present invention is by by titanium dioxide, calcium carbonate, expanded graphite, vermiculite power ball milling is at nanometer grade powder, and and polyvinyl chloride resin, haloflex, the engineering plastics molecules such as nylon 6 fully combine, product is generated after being molded injection moulding by granulation, nanometer grade powder can uniformly and be securely blended in the matrix of product, so that engineering plastics generate larger modification, therefore PVC door-window section bars, which are made, has high temperature resistant, the advantages that antifriction scrape along high mechanical strength, simultaneously, utilize titanium dioxide, calcium carbonate, expanded graphite, vermiculite power itself has flame-retarding characteristic, improve the flame retardant property of PVC door-window section bars.
Description
Technical field
The present invention relates to door-window section bar production technical fields, and in particular to a kind of PVC door-window section bars with flame retardant property
And preparation method thereof.
Background technology
Plastic-steel section bar abbreviation plastic-steel, main chemical compositions are PVC, therefore are also PVC profile.It is the one kind being widely used
Novel construction material, due to its physical property such as rigidity, elasticity, it is corrosion-resistant, anti-aging property is excellent, be typically used as be copper,
The good substitute of the non-ferrous metals such as zinc, aluminium.
It is mainly used for pushing and pulling in building construction, the application of horizontally-opening windows and doors, guardrail, tubing and ceiling material, by new
It is not only light-weight in terms of technological process processing is also widely used in automobile engine protection board, but also good toughness, there is just excellent
Property, sometimes also referred to as alloy plastic-steel.
Although plastic-steel material extensive use, with the development of the society, its performance is continuously improved, for example (,) it is intensity, tough
The performances such as property, heat resistance, heat insulating ability, sound-proofing, antistatic property, ultra-violet resistance.And plastic-steel section bar overwhelming majority in China's is inferior
Proximate matter uses lead salt stabilizer, and finished product lead tolerance is between 0.6%-1.2%.Lead is a kind of harmful substance, when bad
When matter proximate matter aging, leaded dust can be precipitated, can make in blood lead content exceeded after Long Term Contact or even lead poisoning.Therefore it needs
The safety of plastic-steel section bar is improved, while not improving cost.
Invention content
It is an object of the invention to overcome above-mentioned the deficiencies in the prior art, a kind of PVC door and windows with flame retardant property are provided
Proximate matter has excellent flame retardant property and preferable mechanical property, and preparation method is simple, it is easy to accomplish, it is suitable for industrialization
Production.
In order to solve the above-mentioned technical problem, the present invention adopts the following technical scheme that：
A kind of PVC door-window section bars with flame retardant property, are made from the following raw materials in parts by weight：60-80 parts of polyvinyl chloride resin, chlorination
It is 30-40 parts of polyethylene, 6 15-25 parts of nylon, 10-20 parts of glass fibre, 20-30 parts of titanium dioxide, 10-30 parts of calcium carbonate, swollen
Swollen graphite 10-20 parts, 5-15 parts of vermiculite power, 3-8 parts of main flame retardant, 2-6 parts of auxiliary flame retardant, 2-8 parts of compatilizer, toughener 1-
5 parts and 0.5-3.5 parts of stabilizer.
Wherein, it is made from the following raw materials in parts by weight：70 parts of polyvinyl chloride resin, 35 parts of haloflex, 6 20 parts of nylon, glass
15 parts of glass fiber, 25 parts of titanium dioxide, 20 parts of precipitated calcium carbonate, 15 parts of expanded graphite, 10 parts of vermiculite power, 5.5 parts of main flame retardant,
2 parts of 4 parts of auxiliary flame retardant, 5.5 parts of compatilizer, 3 parts of plasticizer and stabilizer.
Wherein, the glass fibre is that alkali-free length is fine, 8-14 microns a diameter of.
Wherein, the main combustion adjuvant is one kind in decabromodiphenylethane or brominated Polystyrene；The auxiliary flame retardant
For antimony containing compounds.
Wherein, the compatilizer is Styrene-Maleic Anhydride Copolymer or maleic anhydride grafted ABS.
Wherein, the plasticizer is diethylene glycol dibenzoate.
Wherein, the stabilizer temperature mass ratio is 2-4：The mixture of 1 zinc stearate and ricinoleic acid calcium.
The present invention also provides the preparation methods of the above-mentioned PVC door-window section bars with flame retardant property, include the following steps：
（1）Titanium dioxide, calcium carbonate, expanded graphite, vermiculite power are milled to 20-120nm granularity powder respectively；
（2）The each component in formula is weighed, the polyvinyl chloride resin weighed, haloflex, nylon 6 is dry at a temperature of 80-90 DEG C
3-5h, other components dry 2-4h at a temperature of 60-70 DEG C；
（3）By step（1）The granularity powder and step of the 20-120nm worn into（2）Polyvinyl chloride resin, haloflex after drying, Buddhist nun
Dragon 6, main flame retardant, auxiliary flame retardant, compatilizer, toughener and stabilizer are uniformly mixed in high-speed mixer together, stirring
Required time is 5-10min；
（4）By step（3）Product is made by the molding of comminutor, injection molding machine or hot injection moulding machine in the dusty material for being sufficiently mixed object.
Wherein, in the step (1), the adjusting of rotational speed of ball-mill is divided into four sections, and constant velocity stage accelerates boost phase, at the uniform velocity
Temperature rise period and deceleration buck stage.
Wherein, the speed of the constant velocity stage is maintained at 30r/min, and acceleration average rate is 6-8r/min；It is described even
It is constant that the speed of fast temperature rise period is maintained at 300r/min, and temperature-averaging accelerates 5-7 DEG C/min；The temperature of the deceleration buck stage
Degree is first down to 200r/min, then keeps 20min, and temperature is down to 30 DEG C from 200 DEG C, and cooling Mean Speed is 4-6 DEG C/min.
Compared with prior art, the present invention has following advantageous effect：
（1）The present invention by by titanium dioxide, calcium carbonate, expanded graphite, vermiculite power ball milling at nanometer grade powder, and with PVC trees
The engineering plastics molecules such as fat, haloflex, nylon 6 fully combine, and product, nanoscale are generated after being molded injection moulding by granulation
Powder can uniformly and be securely blended in the matrix of product so that engineering plastics generate larger modification, therefore PVC door and windows are made
Proximate matter has many advantages, such as high temperature resistant, antifriction scrape along high mechanical strength, meanwhile, utilize titanium dioxide, calcium carbonate, expanded graphite, leech
Mountain flour itself has flame-retarding characteristic, improves the flame retardant property of PVC door-window section bars.
（2）The present invention further increases PVC door-window section bars by main flame retardant and the mutually matched mode of auxiliary flame retardant
Flame retardant property.
（3）The present invention is by adding the function additives such as compatilizer, toughener and stabilizer so that compatibility between each raw material
It is good, and pass through the organic assembling between each raw material so that plastic-steel section bar not only has preferable mechanical strength, while its is fire-retardant and resistance to
Frictional behaviour is good；
（4）The method production efficiency of the offer of the present invention is high, and production cost is low, and labor intensity is low.
