PVC modified hose and preparation method thereof

Abstract

The invention discloses a PVC modified hose which is prepared from the following raw materials in parts by weight: 750 parts of PVC resin powder, 450-500 parts of an environmental-friendly plasticizer, 100-150 parts of a flexible modifier, 20 parts of a stabilizer, 1.2-2 parts of a lubricant, 0.5-1 part of an anti-UV agent and 1.5-2 parts of an antioxidant. The PVC modified hose is prepared by mixing the raw materials, and the adding amount of the flexible modifier is 100-150 parts. Regardless of raised or reduced temperature, the PVC modified hose is stable in flexibility, that is, the condition that the PVC modified hose is knotted to affect normal use as the PVC modified hose is relatively high in temperature in summer to be easily softened and deformed can be avoided, or, the conditionthat the PVC modified hose cannot be stretched normally to use as the PVC flexible hose is relatively low in winter to be easily hardened to a very stiff state can be avoided.

Description

technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to a PVC modified hose and a manufacturing method thereof. Background technique [0002] PVC hoses are inexpensive and practical, and are used in various fields to transport liquids or gases. For example, in the bathroom field, PVC hoses are currently recognized as better water delivery pipes. [0003] The PVC hose needs to maintain a certain degree of flexibility during use to ensure that the PVC hose is in a better state for use by the user, and to avoid the PVC hose being easily softened and deformed due to high temperature in summer, resulting in The PVC hose is knotted and affects normal use, or in winter, due to the low temperature, it is easy to harden and become hard, so that the PVC hose cannot be stretched normally. [0004] In view of this, the present inventor has made in-depth ideas for the many defects and inconveniences caused by the imperfection ...
