Antimony-free flame-retardant polyvinyl chloride wire and cable material and preparation method thereof

Abstract

The invention relates to the field of a polyvinyl chloride wire and cable material, especially to an antimony-free flame-retardant polyvinyl chloride wire and cable material. The formula of the wire and cable material contains the following ingredients, by weight, a. 100 parts of polyvinyl chloride (PVC); b. 45-55 parts of one or more substances selected from aliphatic dibasic acid ester, trimellitate, polyester and an epoxy plasticizer; c. 5-11 parts of one or more substances selected from a compound stabilizer and an epoxy compound; d. 10-50 parts of one or more substances selected from hydrous zinc borate, magnesium hydroxide, aluminium hydroxide, huntite and a compound flame retardant; e. 4-25 parts of one or more substances selected from kaolin, ceramic microbead and silica-alumina mineral powder; f. 0-6 parts of zero or more substances selected form ethylene chloride and acrylate; g. 0.5-0.8 part of one or more substances selected from stearic acid, polyethylene wax and a compound lubricant; and h. 1-2 parts of color masterbatch. By the technical scheme, latent personal safety threat existing due to antimony can be minimized, pollution is reduced, and the wire and cable material is more environmentally-friendly and has higher safety.

Description

Technical field [0001] The present invention involves the field of polyvinyl chloride wire and cable materials, and specially involves a kind of flame -free Pigvlinvyl chloride cable material and its preparation methods. Background technique [0002] Polyethylene is an excellent wire and cable insulation.In the wire and cable industry, it has always occupied an important share. Because it contains chlorine, it can coordinate flame retardant with tritinal dioxide, which is especially suitable for some high flame retardant occasions.However, with the enhancement of people's environmental awareness, studies have shown that 锑 and its compounds can enter the human body through the respiratory tract, digestive tract or skin, which will stimulate people's eyes, noses, throats, and skin. Continuous contact can destroy the heart and liver function.It still does not rule out its potential danger to the human body. Therefore, many regions and countries have listed 锑 as key pollutants and cl...

Problems solved by technology

However, with the enhancement of people's awareness of environmental protection, studies have shown that antimony and its compounds can enter the human body through the respiratory tract, digestive tract or skin, which can irritate people's eyes, nose, throat and skin. Continuous exposure can damage the function of the heart and liver. At present, its potential danger to the human body is still not ruled out, so many regions and countries have listed antimony as a key pollutant and explicitly prohibited the use of antimony
