Embodiment 1

[0050] A rubber-like texture PVC hose, such as figure 1 As shown, it includes an antibacterial layer 1, an inner layer 2, a mesh layer 3, an outer layer 4 and a wear-resistant layer 5 from the inside to the outside. The inner layer 2, the outer layer 4 and the wear-resistant layer 5 are all made of the same PVC material, the only difference is that the filler calcium carbonate is added to the PVC material formula of the inner layer 2 and the outer layer 4, and the PVC material formula of the wear-resistant layer 5 is No filler calcium carbonate was added. The PVC material formula is specially designed. On the one hand, it has a matte surface and good resilience, which is close to the texture of rubber. On the other hand, it has good high and low temperature performance. Both the antibacterial layer 1 and the wear-resistant layer 5 are formed by a co-extrusion process, and the antibacterial layer 1 is made of PTEE material. Mesh layer 3 is wound from 1000D polyester.

Abstract

The invention discloses a rubber texture imitating PVC hose and a production method thereof. The PVC hose sequentially comprises an inner layer, a net layer and an outer layer from inside to outside,wherein the inner layer and the outer layer are both made of a PVC material, and the PVC material comprises, in parts by weight, 50 parts of HPVC resin, 50 parts of matting PVC resin, 60 to 90 parts of DINCH, 4-6 parts of epoxidized soybean oil, 2-4 parts of a matting agent, 8-14 parts of a low temperature resistant modifier, 8 to 14 parts of tackifying resin, 1-1.4 parts of a stabilizer, 0-75 parts of calcium carbonate, and 0.5-1.5 parts of lubricant. Through reasonable design of the formula of the PVC material, on one hand, the prepared PVC hose meets the international standard in environmental protection property, is dry and comfortable in hand feeling, free of oil stain precipitation, tasteless and good in hygienic property, and can be used at the temperature of -20 DEG C to 80 DEG C;on the other hand, the hose is matte in appearance, good in resilience, close to a rubber hose in overall texture, easy to accept by old people and large in market space.

Description

technical field [0001] The invention relates to a PVC hose, in particular to a rubber-like PVC hose and a production method thereof. Background technique [0002] In recent years, rubber garden hoses suitable for farmland mining and water conservancy construction have been widely used, mainly including drainage rubber hoses and pumping rubber hoses. The traditional rubber hose has a matte appearance, a heavy hand feel, and is full of elasticity. It has no obvious change in hardness and softness under high and low temperatures, and has great performance. However, the production process of rubber hose is complicated. The product is generally made through preliminary rubber mixing, tablet pressing, extrusion, high-temperature vulcanization, and stripping of core rods. The odor of the agent, after a period of time, the surface will be oily or frosted, with poor hand feeling and poor sanitation. [0003] Based on the above problems, high-performance PVC hoses are often prepared...
