Elastic hose

Abstract

The invention discloses an elastic hose. The elastic hose is prepared from the following components in parts by weight: 30-70 parts of elastomer resin copolymer, 10-15 parts of nano-calcium carbonate, 1-5 parts of vinyl silane, 4-5 parts of methyl silicone oil, 2-4 parts of triethanolamine, 0.4-0.6 part of benzotriazole, 0.4-0.6 part of turpentine, 1-3 parts of antioxidant and 5-10 parts of titanium dioxide. Compared with the prior art, the PVC compound hose produced by the invention has the advantages that the outer adhesive layer is prepared from high-polymerization-degree PVC or alloy of high-polymerization-degree PVC and common PVC to replace common PVC, so that, on the premise that the cost is not greatly increased, the abrasion resistance and toughness of the PVC compound hose are greatly improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to an elastic hose. Background technique [0002] There are many types of PVC hoses on the market, and most PVC hoses will contact with the outside world during use, causing friction, so the outer layer of the hose needs to have high wear resistance. The inner layer of the hose is generally used to guide the flow of liquid, and the requirements for wear resistance are not high. In the existing PVC composite hose, the inner and outer layers are generally produced with the same formula material. The inner and outer layers of the hose made of ordinary polymerized PVC material have weak wear resistance, resulting in a short service life; the inner and outer layers of the hose made of high polymerized PVC material have enhanced wear resistance and longer service life , but the cost is high and often cannot be accepted by users. Contents of the invention [0003] In view of the deficiencies in the prior art, the technical problem t...
