Elastic hose

Abstract

The invention discloses an elastic hose which 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, 0.1-0.3 part of cyclochloropropane, 1-3 parts of sodium alginate, 1-2 parts of ethylene glycol monobutyl ether, 2-4 parts of lithopone, 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 outer adhesive layer of the PVC composite hose uses high-polymerization-degree PVC or high-polymerization-degree PVC / common PVC alloy instead of common PVC, thereby greatly enhancing the wear resistance and toughness of the PVC composite hose and prolonging the service life on the premise of less cost increase.

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...
