Abstract

The invention discloses a polyvinyl-chloride extinction material and a production method thereof. The polyvinyl-chloride extinction material comprises the following components in parts by weight: 100 parts of PVC (polyvinyl chloride), 80 to 90 parts of dioctyl phthalate, 4.5 to 5.5 parts of compound stabilizers, 1.5 to 2.5 parts of barium stearate, 0.5 to 1 part of initiator, 3 to 4 parts of trimethylolpropane trimethylacrylate, 0.2 to 0.6 part of stearic acid, 55 to 75 parts of light calcium carbonate, and 2 to 3 parts of diallyl maleate. The raw materials are blended at a high speed, mixed and extruded in a reaction manner to prepare the polyvinyl-chloride extinction material. The polyvinyl-chloride extinction material has excellent extinction performance and can be applied to industries of building materials, electric wires and the like.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a polyvinyl chloride matting material and a production method thereof. Background technique [0002] Polyvinyl chloride plastic (also known as PVC) is a general-purpose material with excellent comprehensive properties. It is widely used in building materials, wire and cable industries, and has replaced rubber materials in many aspects. Polyvinyl chloride has the advantages of high mechanical properties, good embrittlement performance, and simple flame-retardant processing technology. Its global usage ranks second among various synthetic materials. According to statistics, in 1995 alone, the production of PVC in Europe was about 5 million tons, while its consumption was 5.3 million tons. In Germany, PVC production and consumption average 1.4 million tons. PVC is being produced and applied all over the world with a growth rate of 4%. In recent years, the growth rate o...
