Problems solved by technology

However, the amount of ABS resin used in this invention patent is large, and the cost of raw materials is high, and the ABS material produced by this technology has high requirements for the balance index of haze and light transmittance, which cannot meet the high light-shielding and light-aging resistance of plastic materials. Requirements and requirements for high surface gloss
In addition, the reference file mainly modified the high haze value of the material, and did not significantly reduce the light transmittance of the material
[0005] The invention patent with the Chinese patent application number 200810029901.8 discloses a flame-retardant anti-aging ABS and its preparation method, but the technology must contain 12-25% by mass of microencapsulated environmentally friendly flame retardants and 4-10% antimony trioxide, which requires high flame retardancy; secondly, the main raw material of this prior art is 60-80% ABS plastic; thirdly, its preparation method includes the following steps: firstly, water, low-bromine flame-retardant Add FR-245 and dispersant to the reaction kettle, emulsify and disperse under high shear for 30-200min to obtain a flame retardant suspension, then mix and heat the flame retardant suspension with melamine-formaldehyde prepolymer to make The melamine-formaldehyde resin is further cross-linked and solidified on the surface of the flame retardant, and the final reacted product is washed with water, filtered, and vacuum-dried to obtain a microencapsulated environmentally friendly flame retardant, and then use the prepared microencapsulated environmentally friendly flame retardant The flame-retardant and anti-aging ABS can only be obtained through continuous processing. The processing technology of this technology is complicated, the processing time is long and the processing cost is high.
In addition, the main purpose of this reference document is to solve the impact of flame retardants on the performance of light stabilizers in the flame-retardant ABS system, and it does not aim at improving the light-shielding performance of the material, which cannot meet the requirements of high light-shielding and low light transmittance of the material.

Description

technical field [0001] The invention relates to the technical field of ABS material modification, in particular to a high light-shielding ABS composite material for IT and electronic and electrical equipment and a preparation method thereof. Background technique [0002] ABS resin (acrylonitrile-butadiene-styrene copolymer, ABS is the acronym for Acrylonitrile Butadiene Styrene) is a thermoplastic polymer material with high strength, good toughness and easy processing. ABS resin is a graft copolymer of acrylonitrile (Acrylonitrile), 1,3-butadiene (Butadiene), styrene (Styrene) three monomers. Its molecular formula can be written as (C 8 h 8 ) x (C 4 h 6 )y·(C 3 h 3 N)z, but in fact it is often a mixture of butadiene-containing graft copolymer and acrylonitrile-styrene copolymer, in which acrylonitrile accounts for 15%-35%, butadiene accounts for 5%-30%, Styrene accounts for 40%-60%, and the most common ratio is A:B:S=20:30:50. At this time, the melting point of ABS re...
