Wear-resistant polyvinyl chloride foam tube

Abstract

The invention discloses a wear-resistant polyvinyl chloride foam tube, which is prepared from the following raw materials: banana leaf, steel fiber, 0.4% lignin coupling agent, azodicarbonamide, sodium bicarbonate, zinc oxide, polyvinyl chloride, potassium hexatitanate whisker, clamshell powder, an antioxidant, hydroxy propyl cellulose, zinc stearate, castor oil, titanium dioxide, butadiene styrene rubber, tartaric acid, lauryl ammonium chloride, glycerin, chlorinated polyethylene, molybdenum disulfide, and a proper amount of deionized water. By the use of potassium hexatitanate whisker, etc., internal structure of the tube is effectively enhanced, and mechanical strength, toughness and wear resistance are all raised. In addition, the wear-resistant polyvinyl chloride foam tube also has good ageing resistance, high mechanical strength and flame retardance, and is worth of promotion.

Description

technical field [0001] The invention relates to the technical field of foamed polyvinyl chloride, in particular to a polyvinyl chloride foamed pipe which is not easy to wear. Background technique [0002] The pipeline that conveys gas in the exhaust equipment is called the air duct, which connects various equipment or components in the system into a whole. Ducts are usually made of a smooth surface material such as polyvinyl chloride pipe. Polyvinyl chloride is one of the five general-purpose plastics and is widely used in many industries such as building materials and packaging. Polyvinyl chloride foam materials are more popular due to their light weight, heat insulation, sound insulation, high specific strength, and insulation. However, while the cost of foam materials is reduced, the mechanical properties are reduced, which greatly limits the use of PVC. Application of foam materials.

Problems solved by technology

Banana fiber can be divided into banana stem fiber and banana leaf fiber. Banana stem fiber has the advantages of general hemp fiber, such as high strength, small elongation, thick and hard fiber, easy moisture absorption and release, and easy dyeing. Banana leaf fiber has Excellent resistance to alkali, phenol, formic acid, chloroform, acetone, adding it to polyvinyl chloride materials can reduce environmental pollution and bring huge economic benefits, and can also improve the chemical corrosion resistance of polyvinyl chloride, but directly adding It will reduce the material performance of polyvinyl chloride itself and limit its application. Banana fiber must be modified to improve its interfacial compatibility with polyvinyl chloride
