Embodiment 1

[0019] After cleaning and arranging the discarded automobile tires, crush them at room temperature to 40 mesh to 120 mesh, separate the iron through magnetic separation, and then use ultrasonic waves (power density p=0.36w / cm 2 ) in the environment for 1 to 2 hours, and perform physical modification and activation to stimulate group activity. Then this active rubber powder is transferred to the container, at normal temperature and 60 Irradiate in Co ray, control the irradiation dose to 40kGy~80kGy, add cellulose acetate acetone solution (solution mass concentration 18%) of 10% of the weight of the rubber powder under stirring, continue to stir and react for 60 minutes under irradiation, and then discharge the material 1. Crushed and packaged to obtain physical and chemically modified rubber powder. This rubber powder can be sold directly as a product, used to mix asphalt to make road paving materials, and can also be used to make plastic runways.

Abstract

The invention discloses a modification method of tire rubber powder, and application thereof, wherein the method comprises the following steps: cleaning and tidying waste automobile tires, crushing tires to 40-120 meshes at constant temperature, acting in ultrasonic wave environment for 1-2 h, and performing physical modification and activation to excite group activity; then transferring active rubber powder into a containers, irradiating the active rubber powder in 60 Co rays at constant temperature, controlling irradiation dosage as 40-80 k G y, adding acetone solution of cellulose acetate which is 10% by weight of rubber powder while stirring, wherein acetone solution of cellulose acetate has mass concentration of 18%; continuously stirring and reacting for 60-120 minutes in irradiation, and then discharging. Modified rubber powder is blended with ardealite, coal ash, lime, cement or water glass and foaming agent in a proportion, and is processed by certain technical lines to produce self-insulation partition wall building blocks. The method provided by the invention is featured with simple technology and less equipment investment, is suitable for mass production, and is industrialized easily, so that the method has better application promotion prospects.

Description

technical field [0001] The invention belongs to a method for comprehensive utilization and disposal of industrial waste resources, and in particular relates to a method of physically and chemically modifying waste tire rubber powder and applying it to making building self-insulating partition wall blocks. Background technique [0002] With the rapid development of the automobile industry and the transportation industry, a large amount of waste tires are accumulated. According to statistics, the annual waste of tires in the world is about 10 million tons, and there are 600,000 tons of waste tires in my country that need to be disposed of urgently every year. These discarded tires take up a lot of land and cause environmental pollution. Waste tires are still a major hidden danger of fire, pollute groundwater sources, and seriously affect people's daily life. At present, the recycling of waste tires has been paid more and more attention by various countries, and has become an...
