Abstract

The invention discloses a method for preparing a rubber plastic foaming thermal-insulation material by utilizing a waste rubber product. The method comprises the following steps: adding the waste rubber product, chlorinated polyethylene, benzoyl peroxide and ethambutol into an internal mixer and internally mixing for 10-15min; adding 1,4-ditert-butyl peroxide isopropyl benzene and triallyl isocyanurate and performing smelting reaction for 5-10min; continuously raising temperature to 120-130 DEG C and then adding expandable microsphere, kieselguhr and nanometer calcium carbonate and foaming for 10-15min; continuously raising temperature to 150-160 DEG C, adding azodicarbonamide and mica powder and foaming for 8-10min; and cooling the reaction and then drying, thereby acquiring the rubber plastic foaming thermal-insulation material.

Description

technical field [0001] The invention belongs to the field of thermal insulation materials, in particular to a rubber-plastic foam thermal insulation material prepared by using waste rubber products and a method thereof. Background technique [0002] Rubber mainly comes from waste tires, waste rubber shoes, waste rubber hoses, tapes and other rubber products, and secondly from scraps and waste products produced in the rubber production process, which belongs to a large category of industrial solid waste. At present, the main source of domestic waste rubber is waste automobile tires. With the rapid development of my country's automobile industry, the number of waste tires continues to rise, and the waste tires produced in China are increasing at a rate of 8% to 10% every year. In recent years, the production of waste tires in China has reached about 250 million, and the recycling rate is only about 50%, which is less than 30% of the developed countries in the West. These tir...
