Problems solved by technology

[0003] The rubber powder used in conventional reclaimed rubber is mainly waste tires, and other products such as waste rubber shoes and inner tubes. In the regeneration process, a large amount of black softener coal tar, petroleum extract, etc. are usually added. The prepared reclaimed rubber has Very unpleasant smell, high pollution, and contains many toxic but carcinogenic chemicals. At present, developed countries have restricted the use of rubber products such as tires containing these chemicals
In addition, conventional reclaimed rubber generally has the problem of poor physical and mechanical properties.

Abstract

The invention discloses an environmental-friendly reclaimed rubber. The environmental-friendly reclaimed rubber is prepared from waste rubber powder and auxiliary materials in a weight ratio of (8-12):(1.5-3). The auxiliary materials are prepared from the following raw materials in parts by weight: 20-40 parts of palm oil, 4-6 parts of tall oil, 5-10 parts of softening agent, 1-4 parts of activating agent, 2-4 parts of ethylene glycol monoethyl ether acetate, 3-10 parts of oxidized polyethylene wax, 1-4 parts of stearic acid, 1-3 parts of sodium tripolyphosphate and 3-5 parts of papermaking sludge ash. The invention also discloses a production method of the environmental-friendly reclaimed rubber. According to the environmental-friendly reclaimed rubber and the production method thereof, the prepared environmental-friendly reclaimed rubber is good in tensile strength and elongation at break and small in odor; physical properties of the reclaimed rubber such as density and ash content can meet the standard requirements of scrap rubber reclaimed rubber; the environmental-friendly reclaimed rubber has no odor or harmful substances, is harmless to the human body, and has significantly improved properties; and the environmental-friendly reclaimed rubber can be used for the production of civilian products, is safe and environmentally friendly, and has broad market prospects.

Description

technical field [0001] The invention relates to the technical field of reclaimed rubber production, in particular to an environment-friendly reclaimed rubber and a production method thereof. Background technique [0002] Every year in our country, a large number of waste rubber products are treated as waste products and garbage, which not only pollutes the environment, but also causes a lot of waste of resources. In recent years, many enterprises have been engaged in the recycling, processing and reproduction of waste rubber products to realize the recycling of waste rubber products and plastic products, which not only solves the problem of environmental pollution, but also realizes the maximum utilization of resources, energy saving and environmental protection. [0003] The rubber powder used in conventional reclaimed rubber is mainly waste tires, and other products such as waste rubber shoes and inner tubes. In the regeneration process, a large amount of black softener co...
