Description
【Technical field】
The invention belongs to thermosetting plastic technical field, and in particular to a kind of translucent fiber reinforced thermoset plastics.
【Background technology】
Fiber reinforced thermoset plastics have that excellent insulating property, density are small, intensity is high, corrosion resistant the features such as, from being born
Since be widely used in the fields such as electronic apparatus, vehicle mechanical, building materials, for replace easy corrosion iron and steel parts and
The thermoplastic components of easy firing, low intensity.
But, current general fibre reinforced thermosetting plastics is due to wherein containing substantial amounts of powder material, such as the powder demoulding
Agent, powder mineral filler and colouring agent so that the product manufactured with it is fully opaque, such as Authorization Notice No.
The patent document of CN103160098B discloses a kind of thermosetting plastics, is prepared from by the raw material of following 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 have good stability,
Intensity and flame retardant effect, but due to containing substantial amounts of calcium carbonate powder filler, so being opaque white or canescence.
However, generally require to manufacture the product model machine of displaying in industry manufacture, so that client can pass through product casing
It was observed that internal structure, it is clear that fiber reinforcement thermosetting molding traditional at present is unable to reach this kind of effect, it is necessary to develop.
【The content of the invention】
It is an object of the invention to provide a kind of fiber reinforced thermoset plastics, optical clarity is high, meets industry manufacture
Double requirement of transparent visual structure.
Preparation method another object of the present invention is to provide above-mentioned fiber reinforced thermoset plastics, can prepare light extraction
Transparency fiber reinforced thermoset plastics high are learned, industry double requirement of transparent visual structure of manufacture is met.
A technical scheme of the invention is：
A kind of fiber reinforced thermoset plastics, it is characterised in that by the raw material preparation comprising following parts by weight material
Into：Thermosetting resin 40-95 parts, low shrinkage additive 5-60 parts, initiator 1-4 parts, magnesia 8-12 parts, releasing agent 2-8 parts,
Reinforcing fiber 10-280 parts.Thermosetting resin (thermosetting resin), refers to produce chemical change after resin is heated,
A kind of gradually hardened forming, then the resin that also do not soften, can not dissolve that is heated；Low shrinkage additive (LSA) is to refer to drop
One class additive of the low resin shrinkage rate during machine-shaping；Initiator (initiator), triggers also known as free radical
Agent, refers to that a class, easily by the compound for being thermally decomposed into free radical (i.e. primary group of free radicals), can be used to trigger alkenes, double vinyl monomers
Radical polymerization and copolymerization, it can also be used to unsaturated polyester (UP) crosslinking curing and high molecular crosslink reaction；Releasing agent
It is used in two interface coatings of the body surface for being easy to adhesion each other, body surface is easy to disengaging, smooth and cleaning
Functional materials.Material can be divided into the transparent material (light transmittance of wavelength 400nm-800nm visible rays according to light transmittance size
More than 80%), trnaslucent materials (light transmittance of 400nm-800nm visible rays is between 50%-80%) and opaque material
(light transmittance of 400nm-800nm visible rays is below 50%).The formula does not contain the serious filler for hindering light to pass through or dye
Material, finished product has optical clarity higher, is translucent fiber reinforced thermoset plastics, and raw material is solved by magnesia
Because of the problem that viscosity is too small caused by the shortage of filler, cannot be molded, it is the insulating properties, close of material that each component cooperates
The characteristics such as degree, intensity meet the requirement of industry manufacture.
Further, above-mentioned fiber reinforced thermoset plastics are prepared from by the raw material comprising following parts by weight material：
Thermosetting resin 45-90 parts, low shrinkage additive 10-55 parts, initiator 2-3 parts, magnesia 8-10 parts, releasing agent 3-7 parts, increase
Strong 20-100 parts of fiber.

Thing, cellulose acetate, cellulose butyrate, thermoplastic polyester, PCL, polyvinyl acetate and polymethyl methacrylate
In one or more.Above-mentioned low shrinkage additive type can improve the dimensional accuracy and presentation quality of thermoset plastic articles),
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 in isopropyl t-butyl carbonate.Above-mentioned initiator is that liquid is easy to addition to operate, can be with arbitrary proportion
Added in formula, with thermally and chemically stability higher, it is easy to storage, while it is comparatively ideal solid to provide thermosetting plastics
Change forming temperature.
Further, above-mentioned reinforcing fiber is in glass fibre, carbon fiber, basalt fibre, polyester fiber, flax fiber
One or more.Different fibers, can provide product different structure intensity, while few fibers have color in itself, can be into
Type product provides lines attractive in appearance, can show fiber flow regime in a mold, and material during for shaping puts offer reference
Foundation, can as the case may be select different kinds of fibers or fibre furnish.
Further, above-mentioned reinforcing fiber is that the acrylic paints solution diluted by 75%-95% (vol) alcohol soaks
Dry reinforcing fiber after color.Fiber reinforced thermoset plastics employ a large amount of fibers as reinforcing material, in hot-forming rank
Section, glass flowing it is sufficiently complex, engineer can not with the nowed forming and fiber distribution consistency degree for visually observing directly product,
The shortcoming that product local strength may be caused not enough, can not improve product design by material nowed forming.This warp
The reinforcing material of acrylic paints dyeing treatment, can not only provide the selection of client's multiple color, while shades of colour fiber can be
During shaping, flow direction of the material in metal die can be embodied, the weight for helping process engineer's regulation material to place
And position, product design is improved by fiber distribution situation in the product, it is uniform beneficial to the glass in product.
Further, above-mentioned releasing agent be the BYK9060 of commercially available Bi Ke auxiliary agents (Shanghai) Co., Ltd., BYK9065,
The mixture of one or more arbitrary proportions in BYK9080.Employ liquid form releasing agent and substituted for traditional stearic acid
Zinc, calcium stearate micro mist releasing agent, make the product after shaping have translucent, specious bright and clean, can be made through shaping
Product see the functioning condition of other coordination portions.
