Abstract

The invention provides a high-light free-spraying material and a preparation method thereof, and relates to the technical field of high polymer materials. The high-light free-spraying material is prepared from the following raw materials of PC resin, AS resin, BDP flame retardant, mineral filler, flexibilizer, an antioxidant and a lubricant. The high-light free-spraying material shows good balance of strength and toughness, the molding shrinkage rate is 0.35-0.45%, the modulus is larger than or equal to 4,000 Mpa, the shock is larger than or equal to 60 J / m, the density is smaller than 1.32 g / cm<3>, the high-light free-spraying material is applied to large size television back cover in the mainstream market, the high-light free-spraying mirror effect is achieved without using an RHCM mold, the production efficiency is improved, the fixed equipment investment is lowered, and an innovative material is provided for green development of the television industry.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-gloss spray-free material and a preparation method thereof. Background technique [0002] At present, the size of TVs is getting larger and larger, and the conventional flame-retardant PC / ABS, flame-retardant ABS, and flame-retardant HIPS materials cannot meet the requirements of the TV, and the lack of rigidity makes the rear shell of the TV easily deformed. The size of TVs is getting bigger and bigger. Conventional flame-retardant PC / ABS, flame-retardant ABS, and flame-retardant HIPS materials have excessive shrinkage, which makes the rear shell of the TV easy to crack due to temperature changes. Mineral powder or glass fiber filling materials can solve the above problems, but the appearance of the parts is dull and the luminosity is insufficient. RHCM molds are required to obtain a high-gloss appearance. RHCM molds have high requirements for the selection of ...
