Abstract
The invention discloses a heat-resistant polyester glass fiber reinforced plastic material. A physical method is employed to conduct ultra-low temperature pretreatment on glass fiber to improve the flexural properties, tensile properties and wear resistance; a high temperature treatment reaches oxidative decomposition of the original glue material on the glass fiber surface, in order to remove the water adsorbed and stored by the glass fiber; a chemical method is used to conduct surface graft modification on a porous carbon nanotube material, so as to gain a cavity structure; when the glass fiber compounds with a matrix, chain segments of polymers enter the cavities to play a similar anchoring effect, thereby increasing the binding force between the glass fiber and polymer interface, and improving the impact resistance of the product. The glass fiber reinforced plastic material supplemented with other effective additives has the characteristics of good interfacial property, and good heat resistance and impact resistance.
Description
Technical field
The present invention relates to glass fibre reinforced plastics technology field, particularly relate to a kind of heat-resistant polyester glass-reinforced plastic material and preparation method thereof.
Background technology
Toy is the angel of children, and toy is with its chromatic colour, and graceful, unusual moulding, dexterous activity, the melodious sound etc. attract curiosity and the attention of child.The wide variety of toy, playing method is changeable, comprise down toy, plastic toy, papery toy, electronic toy, wooden toy, metal toy, leather toy, educational toy, early education toy, glass reinforced plastic toy, juvenile automobile and other miscellaneous toys, be wherein in great demand the most with down toy and juvenile automobile again.Juvenile automobile material often uses metallic substance and plastics, and not only price is high for metallic substance, matter escheat easily gets rusty, plastic crisp easily fall rotten, easily aging.Nowadays many employing glass-reinforced plastic material alternative metals materials and plastics.Glass reinforced plastic and fiber-reinforced plastic, refer generally to glass fiber reinforcement unsaturated polyester, epoxy resin and phenolic resin as matrix resin.Being applied to normal that automobile toy uses is matrix with unsaturated polyester, has light weight and hard, non-conductive, stable performance, the features such as physical strength is high, corrosion-resistant.Though China's glass-reinforced plastic material research and development in recent years obtain remarkable progress, but compare with Foreign Advanced Lerel, also there is a big difference, and main manifestations is poor product quality, kind is few, cost is high, and the bonding force of glass fibre and resin matrix is weak etc., is therefore the sunrise industry having very much development potentiality.
Patent CN104231584A adopts polyvinyl acetate (PVA) and corresponding segmented copolymer to be that low shrinkage additive reduces goods contraction in the curing process, improve the planeness of product surface, the advanced continuously shaped reinforced plastic plate technology of intermediate temperature setting is utilized to improve the degree of cure of product, enhance flexural strength, improve snappiness, finally replacing tradition to have halogen fire retardant with new halogen-free flame retardants, is that flame retardant effect is up to state standards the highest level of regulation.But this literary composition is by resin matrix and glass fibre direct combination, and both poor compatibility, are necessary to add in matrix resin existing glass fibre is in addition modified again.
Summary of the invention
The object of the invention is exactly the defect in order to make up prior art, provides a kind of heat-resistant polyester glass-reinforced plastic material and preparation method thereof.
