Abstract
The invention discloses a sound absorption and noise reduction fiberglass reinforced plastic material. After ultra-low-temperature preprocessing is conducted on glass fiber through a physical method, the bending performance, the tensile property and the interlayer shearing performance of glass fiber are improved, existing sizing materials on the surfaces of the glass fiber are oxidized and decomposed through high-temperature processing, and therefore water stored in and adsorbed to the glass fiber is removed; porous carbon nanotubes, activated carbon powder and other materials are arranged on the surfaces of the glass fiber through graft modification according to a chemical method, the hole structure is achieved, chain segments of some high polymers enter holes when the glass fiber and a substrate are compounded, and the effect similar to anchoring is achieved; in this way, the bonding force between the glass fiber and the polymer interface is increased, the impact property of the product is improved, and the prepared fiberglass reinforced plastic material has the advantages of sound absorption and noise reduction; when the fiberglass reinforced plastic material is applied to the field of toy automobiles, noise can be reduced, and therefore audition of children is protected against interference, and practicability is high.
Description
Technical field
The present invention relates to glass fibre reinforced plastics technology field, particularly relate to a kind of absorbing sound and lowering noise polyester fiberglass steel 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 absorbing sound and lowering noise polyester fiberglass steel and preparation method thereof.
The present invention is achieved by the following technical solutions:
A kind of absorbing sound and lowering noise polyester fiberglass steel, is made up of the raw material of following weight part: unsaturated polyester 111-121, alkali free glass fibre 17-18, carbon nanotube 0.2-0.4, Nano graphite powder 2.1-2.3, carclazyte 12-14, molasses 6-8, vinyl acetate 4-6, morpholine 3.5-3.7, vinyl trichloro silane 8-9.2, activity charcoal powder 5-7, stannous octoate 1.6-1.8, methylethyl ketone peroxide 2.7-3.6,1% aqueous ethanolic solution are appropriate.
The making method of described a kind of absorbing sound and lowering noise polyester fiberglass steel, comprises the following steps:
(1) alkali free 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 510-550 DEG C of temperature, thermal treatment 1-2 hour, obtained pre-treatment alkali free glass fibre of naturally rising again;
(2) by after morpholine, vinyl trichloro silane stirring and evenly mixing 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, molasses maintenance temperature stirs 30-40 minute, add the obtained pre-treatment alkali free glass fibre of step (1) material, activity charcoal powder immersion after 2-4 hour, decompress filter, dries the obtained modification alkali free glass fibre of grinding by filter residue;
(3) unsaturated polyester is put into high mixer, add Nano graphite powder, vinyl acetate mixing 20-30 minute, then with above-mentioned modification alkali free glass fibre 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 carried out very low temperature pre-treatment by physical method by the present invention, improve its anti-bending strength, tensile property, Interlaminar shear strengths, the original sizing material oxygenolysis of fiberglass surfacing is made again through pyroprocessing, and then removing glass fibre stores the water of absorption, by chemical process, graft modification porous carbon nanotube is carried out to its surface again, the materials such as activity charcoal powder, 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, obtained glass-reinforced plastic material has the feature of absorbing sound and lowering noise, be applied to toy car field can the hearing of noise reduction and then child protection interference-free, practical.
