Abstract

The invention provides a matte, high-elasticity and low-temperature-resistant PVC hose. The matte, high-elasticity and low-temperature-resistant PVC hose comprises an inner tube and an outer tube, and the inner tube or the outer tube comprises the following components in parts by mass: 100 parts of PVC, 2-3 parts of a heat stabilizer, 20-30 parts of an environmentally friendly plasticizer, 5-15 parts of a low-temperature-resistant modifier, 5-10 parts of an anti-impact modifier, 2-3 parts of an ultraviolet screening agent, 2-3 parts of pigment, 4-6 parts of a wear-resistant modifier and 1-3 parts of an antioxidant. Outer tube PVC consists of conventional PVC and 25-40 parts by mass of extinction PVC. Correspondingly, the invention further provides a preparation method of the PVC hose. The PVC hose which is low in production cost and simple in production technology, is matte, and has high strength, good impact toughness, good stretching strength and good low temperature resistance is obtained.

Description

technical field [0001] The invention relates to the technical field of PVC materials, in particular to a matte high-elasticity low-temperature-resistant PVC hose and a preparation method thereof. Background technique [0002] PVC, the five general-purpose plastics used next to PE, is a cheap resin, but has good physical and chemical properties. After adding plasticizers, stabilizers and various performance additives to the formula, it can be made It is made into a PVC hose with bright appearance, which is widely used in agricultural irrigation, household cleaning, industrial transportation of fluid media and pneumatic tools and other fields. With the improvement of living standards and the change of aesthetic concepts, people began to pursue high-quality and novel-looking PVC products. PVC hose products with a matte (non-glossy) surface, a high-elastic feel similar to rubber, and low-temperature working environment are widely used by consumers. Those who like it need manufa...
