Preparation method of environment-friendly silicone rubber foaming tube

Abstract

The invention discloses a preparation method of an environment-friendly silicone rubber foaming tube. The method comprises the following steps of putting raw material mixture into an open mill, connecting with a water receiving pipe of a refrigerating machine on the open mill; opening the open mill and the refrigerating machine and rolling the raw material mixture into a standby mixture; placing astandby mixture on a unpowered circular disc of an extruder; starting the extruder and adjusting the eccentricity to obtain the extrudate object; putting the extruded object into an aluminum alloy water tank for heating so as to complete the first section of vulcanization; putting the extruded object into a tunnel type heating oven for heating and the second section of vulcanization is completedto obtain a silicone rubber foaming tube; cutting the silicone rubber foaming tube; expanding the silicone rubber foaming pipe and installing the detachable framework; the raw material mixture comprises a pore-forming agent, inorganic powder, a vulcanization system and a methyl vinyl compound. The preparation method of the environment-friendly silicone rubber foaming tube is simple in disassembly,convenient to install, good in rebound resilience, strong in holding force and good in sweat releasing performance.

Description

technical field [0001] The invention relates to the technical field of foam products, in particular to a method for manufacturing an environment-friendly silicone rubber foam tube. Background technique [0002] The silicone rubber foam tube complies with the US FDA food-grade test. The product has high strength, good resilience, low deformation rate, high elasticity, weather resistance, high and low temperature resistance, acid and alkali resistance, non-slip frosted surface, and good perspiration. The plastic used The production cost of the skeleton is low, easy to produce, high in production efficiency, and can be recycled and used for granulation. In the field of silicone rubber foaming, the commonly used silicone rubber foaming agent is: chemical foaming agent azobisisobutyronitrile (NIBN), product production and storage are regulated by hazardous chemicals, and by-products that damage human nerves will be released during the production process , will destroy the atmosp...

AI Technical Summary

Problems solved by technology

[0003] In the field of bicycles, the grip materials used are: plastic, rubber, and non-silicon rubber foam (produced by molding), which will have the following problems: weather resistance, high and low temperature resistance, non-slip, hot in summer, cold hands in winter, hard Grip feeling, when installing, dip the handle with some soapy water, lubricant or detergent, etc., when installing in winter, scald it with hot water for easy installation

The above steps are installed for more than 20 minutes, but the lubricant residue will have a certain impact on the grip force, and it is easy to slip when riding, which is a hidden danger to personal safety
