Abstract

The invention discloses a non-transparent polyvinyl chloride corrugated sheet and a preparation method thereof. The non-transparent polyvinyl chloride corrugated sheet consists of the following components in parts by weight: 80-100 parts of polyvinyl chloride, 1-5 parts of barium stearate, 0.5-1 part of zinc stearate, 0.5-1 part of stearic acid, 0.5-1 part of triphenyl phosphate, 0.2-0.8 part of ammonium polyphosphate, 0.5-1 part of paraffin, 0.5-1 part of isodecyl diphenyl phosphate, 0.5-2 parts of butyl stearate, 0.2-0.8 part of an ultraviolet light absorber, 0.5-2 parts of colorant, 0.2-0.6 part of organic phosphite and 1-2 parts of epoxidized soybean oil. The preparation method comprises processes of stirring and mixing, plasticizing, pelleting and mould pressing, thus obtaining the product. The non-transparent polyvinyl chloride corrugated sheet provided by the invention is excellent in physical performance, and simultaneously the corrugated sheet is good in flame retardant property.

Description

technical field [0001] The invention belongs to the field of packaging materials, in particular to an opaque polyvinyl chloride corrugated board and a preparation method thereof. Background technique [0002] Plastic corrugated board, also known as plastic hollow board, Wantong board, corrugated board, etc., is a plastic special-shaped board with a shape similar to corrugated paper. Plastic corrugated board can be used as a substitute for cardboard, wood board, aluminum board, glass board and other boards in many fields. Due to the plastic material of plastic corrugated board, it has many advantages compared with cardboard, wood board, aluminum board and glass board. Compared with the plastic solid board of the same material, plastic corrugated board has many unique advantages, such as good mechanical properties: plastic corrugated board has good toughness, impact resistance, high compressive strength, cushioning and shock resistance, high stiffness and good bendability etc...
