Antifreeze PVC material and preparation method thereof

Abstract

The invention discloses an antifreeze PVC material and a preparation method thereof. The antifreeze PVC material is prepared from the following raw materials in parts by weight: 100 to 120 parts of PVC resin, 10 to 15 parts of magnesium stearate, 2 to 4 parts of polyimide particles, 8 to 10 parts of calcene, 10 to 15 parts of kieselguhr, 3 to 5 parts of polyethyleneimine, 5 to 15 parts of epoxidized soybean oil, 5 to 10 parts of polyacrylate latex powder, 1 to 3 parts of ammonium polymethacrylate, 2 to 4 parts of epoxy resin, 2 to 4 parts of dioctyl adipate, 10 to 15 parts of carbon fiber, 5 to 8 parts of ethyl acetate, 3 to 6 parts of butadiene rubber, 4 to 6 parts of chlorinated polyethylene and 0.3 to 1.5 parts of a lubricating agent. The antifreeze PVC material disclosed by the invention is high in low temperature resistance, which can reach minus 75 DEG C to the maximum extent, high in strength, high in toughness and excellent in comprehensive performance; even if the antifreeze PVC material is used under a low temperature condition for a long time, the problems of aging, cracking and the like cannot be caused.

Description

technical field [0001] The invention relates to the technical field of pipe fitting materials, in particular to a frost-resistant PVC material and a preparation method thereof. Background technique [0002] PVC (polyvinyl chloride) is one of the earliest industrialized and widely used general-purpose thermoplastics. It has the characteristics of light weight, high strength, insulation, flame retardancy, and corrosion resistance, but it also has the following characteristics: poor weather resistance, easy deformation; poor toughness , It is easy to be brittle when impacted; the low temperature resistance is poor, the brittleness is greatly affected by temperature, and the frost resistance is poor. Therefore, for special environments such as low temperature environments, current PVC materials cannot reliably meet the needs of long-term use under low temperature conditions. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencie...

[0002] PVC (polyvinyl chloride) is one of the earliest industrialized and widely used general-purpose thermoplastics. It has the characteristics of light weight, high strength, insulation, flame retardancy, and corrosion resistance, but it also has the following characteristics: poor weather resistance, easy deformation; poor toughness , easy to be brittle when impacted; poor low temperature resistance, brittleness is greatly affected by temperature, and poor frost resistance

Therefore, for special environments such as low temperature environments, current PVC materials cannot reliably meet the needs of long-term use under low temperature conditions.
