Description

A kind of high shading rate PC/GF composites and preparation method thereof
Technical field
The present invention relates to polymeric material field, and in particular to a kind of high shading rate PC/GF composites and its preparation side Method and preparation method thereof.
Background technology
Makrolon (abbreviation PC) is the high molecular polymer containing carbonate group in strand, can according to the structure of ester group It is divided into the polytypes such as aliphatic, aromatic series, aliphatic-aromatic.Wherein due to aliphatic and the poly- carbonic acid of aliphatic-aromatic The mechanical performance of ester is relatively low, so as to limit its application in terms of engineering plastics.Only aromatic copolycarbonate is obtained at present Industrialized production.It is most fast as growth rate in five large-engineering plastics due to the particularity on polycarbonate structure General engineering plastic.Three big application fields of PC engineering plastics are glazing, auto industry and electronics, electrical equipment industry, its It is secondary to also have the office equipments such as industrial machinery part, CD, packaging, computer, medical treatment and health care, film, leisure and protector Material etc..PC density is low, be easily worked shaping, is a kind of function admirable, widely used engineering plastics, its light transmittance is up to 90% More than.
SAN (SAN) is a kind of transparent amorphous macromolecule material, the compatibility between PC with And the existing substantial amounts of research of influence to makrolon mechanical property, and achieve many significant achievements.But PC/SAN bodies Be optical property research it is relatively fewer.
Being commonly used for matching light scattering agent mainly has inorganic particle, such as silica, calcium carbonate, titanium dioxide, sulphur Sour barium etc., or organic scattering object particle, such as acrylate, organic siliconresin, styrene resin.But inorganic particle with The poor compatibility of matrix material, is difficult to be dispersed in matrix material, and the addition of inorganic particulate can cause material transmissivity Significantly decline, and deteriorate other physical properties of makrolon；There is notch-sensitive shortcoming in itself in makrolon material, After the inorganic scattering particles for adding more amount, more stress concentration point can be formed, notch sensitivity increase makes the performance of material Deterioration；Inorganic scattering particles disperses bad in resin, can form the bad orders such as more pit and organic light diffusing particles Compatibility with matrix is preferable, although will also result in the decline of light transmittance while material mist degree is improved, but fall compared with Inorganic particle is much smaller, and its shortcoming is that the price of conventional organic light diffusing particles is higher, has increased considerably light-scattering material Production cost.Therefore how to overcome these problems, be that blending method prepares one of research direction of light-scattering material.
Glass fibre (GF) is a kind of inorganic non-metallic material of excellent performance, and species is various, and advantage is good insulating, resistance to Hot strong, corrosion resistance is good, high mechanical strength, but having the disadvantage property is crisp, and wearability is poor.It is using glass marble or discarded glass as Raw material is manufactured into through high temperature melting, wire drawing, doff, the technique such as weave cotton cloth, and a diameter of several microns of its monofilament are to twenties Micron, equivalent to the 1/20-1/5 of a hairline, is all made up of per bundle fiber precursor hundreds of even thousands of monofilament.Glass Fiber can be generally added in composite with the physical and mechanical properties of reinforcing material.
At present, the research of existing a large amount of glass fiber reinforced polycarbonate composites, but it is directed to high poly- of shading rate It is less that carbonic ester glass fibre meets investigation of materials, it is impossible to gives full play to the advantage of polycarbonate glass fibrous composite.
