Abstract
A high-strength polyvinyl chloride composite material is provided. The composite material comprises 50-80 parts by mass of polyvinyl chloride, 10-30 parts by mass of alkali-free short glass fibers, 5-20 parts by mass of wood powder, 0-5 parts by mass of bisphenol A type epoxy resin, 0-0.4 part by mass of an alicyclic curing agent, 0.2-1 part by mass of a silane coupling agent and 1-10 parts by mass of auxiliary agents. The glass fibers are utilized to enhance strength of the polyvinyl chloride, and the epoxy resin is added to perform in-situ cutting, and therefore the composite material is enhanced in strength and good in mechanical performance. The wood powder that is cheap is added so that the cost of the composite material is low.
Description
Technical field
The invention belongs to polyvinyl chloride composite materials field, relate to a kind of high-strength polyvinyl chloride composite materials.
Background technology
Polrvinyl chloride (PVC) is that a kind of yield is bigger, cheap and the general-purpose plastics of high comprehensive performance, it is used widely in the field such as medical, chemical industry, electrical equipment, decoration, but PVC there is also, and such as impact strength is low, poor heat stability, the shortcoming such as easily decomposes, limits the range of application of PVC.In order to overcome the above shortcoming, improve the comprehensive mechanical property of PVC, it is possible to adopt multiple material it to be carried out blended or filling-modified, for instance can adopt fiber that it is carried out enhancing modified, adopt Wood flour filled polrvinyl chloride can prepare wood plastic composite etc..
Summary of the invention
It is an object of the invention to provide a kind of high-strength polyvinyl chloride composite materials, adopt glass fibre that polrvinyl chloride is strengthened, and add epoxy resin and carry out in-situ solidifying, improve the intensity of polrvinyl chloride further, the composite materials property of preparation is good, and add cheap wood powder, composite less costly.
For achieving the above object, the technical solution used in the present invention is:
A kind of high-strength polyvinyl chloride composite materials, it is characterised in that it consists of with parts by weight:
Polrvinyl chloride 50～80 parts,
Alkali-free short glass fiber 10～30 parts,
Wood powder 5～20 parts,
Bisphenol A type epoxy resin 0～5 part,
0～0.4 part of alicyclic firming agent,
Silane coupler 0.2～1 part,
Auxiliary agent 1～10 part.
Preferably, with parts by weight, it consists of described high-strength polyvinyl chloride composite materials:
Polrvinyl chloride 60～65 parts,
Alkali-free short glass fiber 18～22 parts,
Wood powder 8～10 parts,
Bisphenol A type epoxy resin 2～4 parts,
0.1～0.3 part of alicyclic firming agent,
Silane coupler 0.2～0.5 part,
Auxiliary agent 4～7 parts.
Preferably, the particle size range of described wood powder is 60～100 orders.
Preferably, described auxiliary agent is the mixture of one or more of heat stabilizer, lubricant, plasticizer.
The preparation method that present invention also offers a kind of high-strength polyvinyl chloride composite materials, comprises the following steps:
Initially with silane coupler, alkali-free short glass fiber and wood powder carried out surface modification, more modified glass fibre and wood powder are mixed 5 ~ 10min with polrvinyl chloride and various auxiliary agent thereof in high-speed mixer；Then bisphenol A type epoxy resin and alicyclic firming agent thereof are weighed, add in above-mentioned compound, plasticate 5min in 180 DEG C of double; two roller mills, plasticizing is uniformly, compression molding is carried out again on vulcanizing press, briquetting pressure 17MPa, forming temperature 180 DEG C, molding time 5 ~ 12min, obtain polyvinyl chloride composite materials.
The present invention is had the advantages that
(1) the high-strength polyvinyl chloride composite materials of one provided by the invention, adopts glass fibre that polrvinyl chloride is strengthened, and adds epoxy resin and carry out in-situ solidifying so that the intensity of polyvinyl chloride composite materials is improved, good mechanical properties；
(2) composite of the present invention adds cheap wood powder, less costly.
