High-temperature-resisting soft PVC (Polyvinyl Chloride) pipe fitting

Abstract

The invention discloses a high-temperature-resisting soft PVC (Polyvinyl Chloride) pipe fitting. The high-temperature-resisting soft PVC pipe fitting is composed of following components in parts by weight: 40-50 parts of polyvinyl chloride resin, 15-20 parts of crossed starch, 2-6 parts of magnesium stearate, 3-8 parts of hexamethylphosphoric triamide, 3-5 parts of PE (Polyethylene) wax with a high molecular weight, 2-8 parts of a wear-resisting modifying agent and 3-5 parts of powdered paraffin. According to the high-temperature-resisting soft PVC pipe fitting, hxamethylphosphoric triamide and the crossed starch are added so that the oxidization resistance of the PVC pipe fitting is greatly improved; the cost of the components is low and the high-temperature-resisting soft PVC pipe fitting is suitable for popularization and application; a high-temperature-resisting inflaming retarding and environment-friendly PVC modified material prepared from a plurality of environment-friendly materials has a smooth appearance and does not contain phthalate, polycyclic aromatic hydrocarbons, free phenols, free phenol flame retardants or boron compounds; the environment-friendly performance is better than national standards including European Union ROHS (Restriction of the use of certain Hazardous Substances), DEHP (Di-(2-ethylhexyl)phthalate), ATBC (Acetyl Tributyl Citrate) and the like; the high-temperature-resisting soft PVC pipe fitting can be widely applied to industrial fields of automobiles, electronic devices, instruments and meters, textiles, buildings and the like.

Description

technical field [0001] The invention relates to the technical field of polyvinyl chloride composite materials, in particular to a high-temperature-resistant soft PVC pipe. Background technique [0002] The structure of PVC reinforced hose is generally: inner layer, fiber reinforced interlayer and outer layer. The characteristics of this reinforced hose are: good pressure resistance, strong tensile strength, good corrosion resistance, small quality, and low price. The cost performance is generally better than that of pure PVC hoses, fire hoses, etc. It is widely used in fields such as farmland irrigation and the transportation of fluid media in the food industry. However, the research work on the formulation design of inner and outer pipes has not been satisfactory for a long time , the performance in its mechanical properties or other aspects is not very good. Contents of the invention [0003] In view of the deficiencies in the prior art, the technical problem to be ...
