Embodiment 1

[0020] A kind of method utilizing waste rubber to prepare foam insulation material, comprises the following steps:

[0021] (1) Ingredients: The thermal insulation material is composed of the following raw materials in parts by weight:

[0022] Waste rubber 70, calcium zeolite 10, 2,6-di-tert-butyl-p-cresol 0.04, methyl nylon acid 3, polylactic acid 4, high-temperature adhesive 0.2, pore-forming agent 0.7, hexadecyl trimethyl chloride Ammonium chloride 0.6, polystyrene 8, oxidized polyethylene wax 3, divinylbenzene 0.3, foaming agent 2, triethanolamine oleate 0.7, zinc stearate 0.6;

[0023] (2) Take the waste rubber from the above raw materials, mix it with methyl nylon, send it into an oil bath at 150°C, heat it for 20 minutes, cool it after discharging, grind it into fine powder, mix it with zinc stearate, and send it to Put it into a microwave dryer, microwave for 20 minutes, the microwave frequency is 2500 MHz, and the discharged material is cooled to normal temperature ...

Abstract

The invention discloses a method using waste rubber to prepare a foaming thermal insulation material. The method is characterized in that the thermal insulation material containing multipole micro-pores inside is prepared by using the waste rubber through foaming treatment, scolecite containing micro-pores is added, and the micro-pores inside are allowed to be stable by blending N-Hexadecyltrimethylammonium Chloride and a pore-forming agent. The thermal insulation material prepared by the method is good in strength and pressure resistance, good in stability and high in comprehensive quality.

Description

technical field [0001] The invention mainly relates to the field of thermal insulation materials, in particular to a method for preparing foamed thermal insulation materials from waste rubber. Background technique [0002] Waste rubber products continue to increase and grow rapidly, but the recycling rate is low, and a large number of rubber products are discarded at random and cannot be fully utilized, resulting in waste of resources. According to the statistics of the World Environmental Health Organization, the stock of discarded tires in the world has reached more than 3 billion, and it is growing at a rate of about 1 billion per year. The Ministry of Industry and Information Technology of the People's Republic of China pointed out in the 2010 Guiding Opinions on the Comprehensive Utilization of Waste Tires that in 2009 my country's tire consumption accounted for about 70% of the country's total consumption of rubber resources, and 233 million waste tires were produced a...
