Abstract

The invention provides a high-temperature-resistant PVC enhanced hose which comprises an inner tube and an outer tube. The inner tube or the outer tube is prepared from, by mass, 100 parts of PVC, 1.5-3 parts of heat stabilizer, 20-35 parts of trioctyl trimellitate, 5-15 parts of polyester plasticizer, 2-3 parts of toughening modification agent, 10-20 parts of calcium carbonate filler, 1-3 parts of antioxidant and one part or less of toner. Correspondingly, the invention further provides a preparation method of the high-temperature-resistant PVC enhanced hose. The prepared high-temperature-resistant PVC enhanced hose is excellent in heat stability, breaking tenacity and tensile strength; compared with PVC resin in the prior art, the high-temperature-resistant PVC enhanced hose is excellent in performance, nontoxic and environmentally friendly, meets the requirements of national laws and regulations and industrial standards, and has the quite considerable application market.

Description

technical field [0001] The invention relates to the technical field of PVC materials, in particular to a high-temperature resistant PVC reinforced 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. [0003] At present, the commonly used PVC reinforced water delivery hose is made of inner and outer layers of PVC material, and a layer of polyester fiber mesh is wound in the middle, and a negative pressure is formed by vacuum forming machine head, so that the PVC adhesive layer can be closely pasted. Structure together. It is mainly suitable ...
