Modified tourmaline used for anion high-pressure rubber hose material and preparing method of the modified tourmaline

Abstract

Modified tourmaline used for an anion high-pressure rubber hose material and a preparing method of the modified tourmaline are disclosed. The modified tourmaline is prepared from following raw materials by weight: 50-70 parts of tourmaline, 15-25 parts of a mineral product named as "lvshoushi" by the inventor, 10-15 parts of six-ring rock, 4-8 parts of barium petroleum sulfonate, 3-6 parts of bromo-octyl-phenolic curing resin, 5-10 parts of cane molasses, 2-4 parts of trithiocyanuric acid, 1.5-2.5 parts of N-tert-butyl-2-benzothiazolesulfenamide, 1-2 parts of 4,4'-thio-bis(6-t-butyl-3-methyl phenol), 10-15 parts of cork powder, 4-6 parts of low-molecular-weight polyisobutylene, 10-15 parts of calcium borate, 5-10 parts of ammonium tetramolybdate, 5-10 parts of trixylenyl phosphate, 2-4 parts of nanometer lanthanum oxide, 1.5-2.5 parts of N-oleoylsarcosine, 4-8 parts of oxidized paraffin, 45-65 parts of styrene-isoprene block copolymer, 20-30 parts of high density polyethylene and 3-6 parts of auxiliary agents. The modified tourmaline is capable of enhancing comprehensive properties of products, releasing high-concentration anions under excitation in a static state, purifying air and eliminating peculiar smell, and is stable in performance and durable in efficacy. The modified tourmaline plays an extremely important role for developing tourmaline functionalized high-pressure rubber hoses.

Description

technical field [0001] The invention relates to a modified tourmaline used as an anion high-pressure rubber hose material and a preparation method thereof, belonging to the technical field of inorganic fillers. Background technique [0002] In recent years, tourmaline has been widely used in environmental protection, health care, electronics, medicine, chemical industry, light industry, building materials and other fields due to its characteristics of emitting far infrared rays, releasing negative ions, and weak current. With the gradual research on the value-added application of tourmaline, its application as a mineral filler in the polymer material industry such as plastics and rubber and the field of composite materials has also attracted more and more attention. However, tourmaline is a boron-containing ring-structured silicate mineral, and its powder and polymer surface properties are quite different. Direct filling will easily lead to some performance degradation and b...

Problems solved by technology

However, tourmaline is a boron-containing ring-structured silicate mineral, and the surface properties of its powder and polymer are quite different. Direct filling will easily lead to some performance degradation and brittleness of the composite material, which will affect the composite material. The overall comprehensive performance, therefore, tourmaline must be modified
