Abstract

The invention discloses a halogen-free flame-retardant TPVC ( polyvinyl chloride elastomer) material and a preparation method therefor. The halogen-free flame-retardant TPVC material is prepared from the following components in parts by weight: 100 parts of PVC resin, 50-100 parts of a plasticizer, 5-10 parts of a heat stabilizer, 2-4 parts of a lubricant and 40-100 parts of a halogen-free flame retardant; the plasticizer consists of dioctyl terephthalate, epoxy fatty acid methyl ester, diphenyl isooctyl phosphate and chlorinated paraffin in a weight ratio of 100 to (10-20) to (100-50) to (5-15); and the halogen-free flame retardant consists of magnesium hydroxide, microencapsulated red phosphorus, antimonous oxide and zinc borate in a weight ratio of 100 to (10-20) to (5-15) to (5-15). The halogen-free flame-retardant TPVC material disclosed by the invention has relatively good flame resistance and mechanical properties, and belongs to a green environment-friendly material which is harmless on a human body and environment.

Description

technical field [0001] The invention relates to a polymer composite material and a preparation method thereof, in particular to a halogen-free flame-retardant TPVC material and a preparation method thereof. Background technique [0002] PVC is a commonly used general-purpose plastic. It has the advantages of wide source, low price, high strength and corrosion resistance. It is widely used in construction, chemical industry, medical equipment and other fields, especially in the manufacture of PVC elastomer (TPVC for short). And the field of application is becoming more and more extensive. The main reason is that TPVC is convenient to manufacture, easy to form and process, has good elasticity, good low temperature resistance, and aging resistance, and has a tendency to replace traditional rubber manufacturing and processing. [0003] The existing problems of TPVC materials mainly include: (1) In the process of manufacturing TPVC materials, a large amount of plasticizers need ...
