Abstract
The invention discloses a fire-resistant fiberglass reinforced plastic material. Glass fibers are firstly subjected to ultralow-temperature pretreatment through a physical method, the bending resisting performance, tensile performance and interlayer shearing performance of the glass fibers are improved, original glue on the surfaces of the glass fibers is oxidatively decomposed through high-temperature treatment, then water stored and adsorbed by the glass fibers is removed, the surfaces of the glass fibers are grafted with a modified porous carbon nano tube material through a chemical method, and a cavity structure is arranged; when the glass fibers and a matrix are compounded, a few of high polymer chain segments enter cavities, a function similar to anchoring is achieved, and therefore the bonding force between the glass fibers and a polymer interface is increased, and the impact-resisting performance of the product is improved. The process is simple, production cost is low, the manufactured fiberglass reinforced plastic material is high in mechanical property and fire resistance, and a manufactured automobile toy is high in safety performance.
Description
Technical field
The present invention relates to glass fibre reinforced plastics technology field, particularly relate to a kind of fire retardant 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 fire retardant polyester glass-reinforced plastic material and preparation method thereof.
The present invention is achieved by the following technical solutions:
A kind of fire retardant polyester glass-reinforced plastic material, is made up of the raw material of following weight part: unsaturated polyester 115-120, glass fibre 16-18, carbon nanotube 0.7-0.9, quartz sand 7-9, glucose 2.1-2.4, tri (propylene glycol) diacrylate 4.2-4.8, superfine alumina silicate 0.5-0.7, magnesium chloride 0.2-0.4, polypropylene fibre 4-6, microcrystalline wax 6-8, dimethoxydiphenylsilane 9.4-9.8, methylethyl ketone peroxide 2.3-2.6,1% aqueous ethanolic solution are appropriate.
The making method of described a kind of fire retardant polyester glass-reinforced plastic material, comprises the following steps:
(1) glass fibre is positioned in super low temperature equipment in subzero 100 DEG C to subzero 200 DEG C of super low temperature 10-15 hour, taking-up is risen again naturally, put into retort furnace at 535-590 DEG C of temperature, thermal treatment 1-2 hour, obtained pretreated glass fiber of naturally rising again;
(2) by dimethoxydiphenylsilane with the volume ratio ultrasonic disperse of 1:50 in 1% aqueous ethanolic solution, be warming up to 80-90 DEG C, add carbon nanotube, tri (propylene glycol) diacrylate, glucose maintenance temperature stirring 30-40 minute, add the obtained pretreated glass fiber of step (1) material, quartz sand, polypropylene fibre immersion after 2-4 hour, decompress filter, dries the obtained modified glass-fiber of grinding by filter residue;
(3) unsaturated polyester is put into high mixer, adds microcrystalline wax, superfine alumina silicate mixing 20-30 minute, then with above-mentioned modified glass-fiber and other remaining component compounds, finally in a mold 75-80 DEG C solidification 10-15 minute, the normal temperature demoulding, discharging.
Advantage of the present invention is: after glass fibre is first carried out very low temperature pre-treatment by physical method by the present invention, improve its anti-bending strength, tensile property and Interlaminar shear strengths, the original sizing material oxygenolysis of fiberglass surfacing is made through pyroprocessing, and then removing glass fibre stores the water of absorption, by chemical process, graft modification porous carbon nano-tube material is carried out to its surface again, there is void structure, treat that glass fibre and matrix carry out compound tense, the segment of some superpolymer enters into hole, play similar anchorage effect, thereby increase the bonding force between glass fibre and polymer interface, improve the impact resistance of product, present invention process is simple, production cost is low, obtained glass-reinforced plastic material mechanical property is high, resistivity against fire is strong, the toy car safety performance made is high.
