Abstract

The invention relates to a formula and preparation method of an antifreezing PVC (polyvinyl chloride) tube. The invention is characterized in that the PVC tube is prepared from the following components in parts by weight: 60-100 parts of PVC, 2-13 parts of reinforcer, 3-6 parts of antioxidant, 1-4 parts of antifreeze agent, 20-40 parts of calcium carbonate and 4-8 parts of paraffin. The antioxidant is B561, the antifreeze agent is methanol, and the reinforcer is DH-22. The antioxidant and antifreeze agent are utilized to effectively protect the PVC tube from rupture due to severe environments. The reinforcer can enhance the hardness of the tube. The formula is simple, thereby saving the cost of the enterprises.

Description

Technical field: [0001] The invention relates to a PVC pipe material, in particular to a formulation of an antifreeze PVC pipe material and a preparation method thereof. Background technique: [0002] At present, with the development of science and technology, PVC materials are also widely used in many fields, such as drainage pipes, door and window profiles, etc., because of their light material, flame retardant, good acid and alkali resistance, low price, and convenient installation. , At present, it has gradually replaced metal pipes. However, in the cold winter, PVC pipes will break due to environmental changes, which will affect the use of pipes. Invention content: [0003] The technical problem to be solved by the present invention is to provide a formula and preparation method of a frost-resistant PVC pipe, so that the PVC pipe will not break due to cold and dry weather. [0004] The object of the present invention is achieved like this, a kind of formula of antif...
