Abstract

The invention discloses a 6-17mm-thick polyvinyl chloride foamed poster board and a preparation method thereof, belonging to the technical field of polyvinyl chloride boards. The poster board solves the problem of incompatibility between low density and high hardness in the prior art. The poster board is prepared from 60-80 parts of polyvinyl chloride SG8 resin, 30-40 parts of light calcium carbonate, 30-40 parts of poster moldboard reclaimed material, 13-14 parts of foaming regulator 903, 2.4-3.2 parts of lead salt composite stabilizer, 0.6-0.7 part of internal lubricant ZB-60, 0.4-0.5 part of polyethylene wax, 0.1-0.3 part of AP, 0.2-0.3 part of plasticizer OA3, 0.9-1.0 part of heat-release AC (azodicarbonamide) foaming agent, 1.3-1.8 parts of heat-absorption Zhongkai c-2 foaming agent and 0.07 part of blue light whitener. The preparation method comprises the following steps: mixing, plastifying and foaming, and extruding to obtain the finished product. The density of the polyvinyl chloride foamed poster board is 0.3-0.4 g / cm<3>, and the thickness is 6-17mm.

Description

technical field [0001] The invention relates to a polyvinyl chloride foamed advertising board with a thickness of 6-17 mm and a preparation method thereof, belonging to the technical field of polyvinyl chloride boards. Background technique [0002] In recent years, the country has vigorously advocated the development of energy-saving and low-consumption products. Plastic formwork is an energy-saving and environmentally friendly product. Therefore, the promotion and application of plastic formwork is a way to save resources and save energy. important measures. Among them, the polyvinyl chloride foam material has processing properties such as sawing, nailing, planing, and sticking, and is waterproof, fireproof, insect-proof, alkali-resistant, anti-corrosion, sound-proof, and has good stability and weather resistance. Features, has been well developed, and is widely used in furniture boards, construction boards, advertising boards, etc. [0003] For polyvinyl chloride foamed ...
