Description
[technical field]
The invention belongs to thermosetting plastic technical fields, and in particular to a kind of translucent fiber reinforced thermoset plastics.
[background technique]
Fiber reinforced thermoset plastics have the characteristics that excellent insulating property, density are small, intensity is high, corrosion resistant, from birth
Since be widely used in the fields such as electronic apparatus, vehicle mechanical, building materials, for replace be easy corrosion iron and steel parts and
The low thermoplastic components of easy firing, intensity.
But general fibre reinforced thermosetting plastics is due to wherein containing a large amount of powder substance at present, as powder demoulds
Agent, powder mineral filler and colorant so that with the product that it is manufactured be it is fully opaque, such as Authorization Notice No.
The patent document of CN103160098B discloses a kind of thermosetting plastics, is prepared by following raw material in parts by weight: insatiable hunger
With 95 parts of polyester resin, 5 parts of polymethyl methacrylate micro mist, 300 parts of calcium carbonate fine powder, initiator TRIGONOX 141 2
Part, 0.6 part of calcium hydroxide micro mist, 6 parts of zinc stearate micro mist, 45 parts of glass fibre.Although the invention is with good stability,
Intensity and flame retardant effect, but due to containing a large amount of calcium carbonate powder filler, so being opaque white or canescence.
However, the product model machine of manufacture displaying is generally required in industry manufacture, so that client can penetrate product casing
Observe internal structure, it is clear that fiber reinforcement thermosetting molding traditional at present is unable to reach this kind of effect, needs to develop.
[summary of the invention]
The purpose of the present invention is to provide a kind of fiber reinforced thermoset plastics, and optical clarity is high, meet industry manufacture
The requirement of double of transparent visual structure.
Another object of the present invention is to provide the preparation methods of above-mentioned fiber reinforced thermoset plastics, can prepare light
The high fiber reinforced thermoset plastics of transparency are learned, the requirement of industry double of transparent visual structure of manufacture is met.
A technical solution of the invention is:
A kind of fiber reinforced thermoset plastics, which is characterized in that by the raw material preparation comprising following parts by weight material
At: 40-95 parts of thermosetting resin, 5-60 parts of low shrinkage additive, 1-4 parts of initiator, 8-12 parts of magnesia, 2-8 parts of release agent,
10-280 parts of reinforcing fiber.Thermosetting resin (thermosetting resin) generates chemical change after referring to resin heating,
Gradually hardened forming, then a kind of heated resin that does not also soften, can not dissolve；Low shrinkage additive (LSA) is to refer to drop
A kind of additive of low resin shrinkage rate during machine-shaping；Initiator (initiator), also known as free radical cause
Agent, it is a kind of easy by the compound for being thermally decomposed into free radical (i.e. primary group of free radicals) to refer to, can be used for causing alkenes, double vinyl monomers
Free radical polymerization and copolymerization, it can also be used to the crosslinking curing and high molecular crosslink of unsaturated polyester (UP) react；Release agent
It is used in an interface coating of the body surface that two are easy to adhere each other, body surface is made to be easy to be detached from, is smooth and clean
Functional materials.Material can be divided into the transparent material (light transmittance of wavelength 400nm-800nm visible light according to light transmittance size
80% or more), trnaslucent materials (light transmittance of 400nm-800nm visible light is between 50%-80%) and opaque material
(light transmittance of 400nm-800nm visible light is below 50%).The formula is without containing the serious filler for hindering light to pass through or dye
Material, finished product optical clarity with higher are translucent fiber reinforced thermoset plastics, solve raw material by magnesia
Because filler shortage caused by viscosity is too small, can not form the problem of, it is the insulation performance, close of material that each component, which cooperates,
The characteristics such as degree, intensity meet the requirement of industry manufacture.
Further, above-mentioned fiber reinforced thermoset plastics are prepared by the raw material comprising following parts by weight material:
45-90 parts of thermosetting resin, 10-55 parts of low shrinkage additive, 2-3 parts of initiator, 8-10 parts of magnesia, 3-7 parts of release agent, increase
Strong 20-100 parts of fiber.
Further, above-mentioned thermosetting resin is one or more of unsaturated polyester resin, vinyl ester resin.No
Saturated polyester resin has good craftsmanship, and vinyl ester resin also has good while having good process
Structural strength and corrosion resistance.
Further, above-mentioned low shrinkage additive is polyethylene, polystyrene and its copolymer, polyvinyl chloride and its copolymerization
Object, cellulose acetate, cellulose butyrate, thermoplastic polyester, polycaprolactone, polyvinyl acetate and polymethyl methacrylate
One or more of.Above-mentioned low shrinkage additive type can improve the dimensional accuracy and presentation quality of thermoset plastic articles),
It can also add in any proportion.
Further, above-mentioned initiator is peroxidized t-butyl perbenzoate, the peroxidating 2 ethyl hexanoic acid tert-butyl ester, peroxidating
One or more of isopropyl t-butyl carbonate.Above-mentioned initiator is liquid convenient for addition operation, can be with arbitrary proportion
It is added in formula, thermally and chemically stability with higher, convenient for storage, while it is comparatively ideal solid to provide thermosetting plastics
Change forming temperature.
Further, above-mentioned reinforcing fiber is glass fibre, in carbon fiber, basalt fibre, polyester fiber, flax fiber
One or more.Different fibers, can provide product different structure intensity, while few fibers itself are there are color, can at
Type product provides beautiful lines, can show the flow regime of fiber in a mold, and material when to form, which is put, provides reference
Foundation can select different kinds of fibers or fibre furnish as the case may be.
Further, above-mentioned reinforcing fiber is to impregnate by the diluted acrylic paints solution of 75%-95% (vol) alcohol
Dry reinforcing fiber after color.Fiber reinforced thermoset plastics use a large amount of fibers as reinforcing material, in hot-forming rank
Section, glass flowing it is sufficiently complex, engineer cannot with the nowed forming and fiber distribution consistency degree for visually observing directly product,
The disadvantage of product local strength deficiency may be caused, product design can not be improved by material nowed forming.This warp
The reinforcing material of acrylic paints dyeing processing, can not only provide the selection of client's multiple color, while various colors fiber can be
When molding, flow direction of the material in metal die can be embodied, process engineer is helped to adjust the weight that material is placed
And position, product design is improved by the distribution situation of fiber in the product, it is uniform conducive to the glass in product.
Further, above-mentioned release agent be commercially available Bi Ke auxiliary agent (Shanghai) Co., Ltd. BYK9060, BYK9065,
The mixture of one or more of BYK9080 arbitrary proportion.Traditional stearic acid is substituted using liquid form release agent
Zinc, calcium stearate micro mist release agent make product after molding have translucent, specious bright and clean, can be through molding system
Product see the functioning condition of other coordination portions.
