Problems solved by technology

[0002] As early as the 1980s, research institutions in our country did a lot of work on the application and promotion of vulcanized rubber powder in tires. However, since the reform and opening up had just begun, people's living standards and the convenience of transportation had not been raised for a while. Although the level of social industrialization is not high and tires are not in short supply, it is not surprising that the application of reclaimed rubber and its rubber powder has been neglected. On the one hand, the price of natural rubber (NR) was less than one dollar at that time (RMB to USD 5:1), synthetic rubber is 3-4 yuan / kg, and the concept of resources is relatively weak, so state-owned enterprises were not willing to take risks in this work except for the wide application of synthetic rubber, which was encouraged by national policies. A lot of investment

Embodiment Construction

[0012] The purpose of the present invention is to provide a process for the modification of vulcanized rubber, which greatly reduces the production cost, and has good compatibility with the new rubber and stable mechanical properties.

[0013] The technical scheme of the present invention is: a process for modifying vulcanized rubber powder, which is characterized in that: with 40-60 mesh rubber powder as the basic amount, the weight ratio of each component is: A, 40-60 mesh vulcanized rubber powder 30 -70 parts B, natural rubber 30-70 parts C, tackifier 1-4 parts D, activator 2-5 parts E, softener 1-4 parts F, vulcanizing agent 2-5 parts

[0014] JF and NR performance comparability analysis model setting;

[0015] As we all know, when a small amount of reclaimed rubber is used in the formula, a certain effective rubber content is generally included according to the performance of the reclaimed rubber. Therefore, the reasonable combination and substitution of vulcanized rubbe...

Abstract

The invention relates to a technology for modifying vulcanized rubber powder. According to the technology, 40-60 meshes of rubber powder is served as the basic amount; in ratio by weight, the following components are respectively: A, 30-70 parts of vulcanized rubber powder in 40-60 meshes; B, 30-70 parts of nature rubber; C, 1-4 parts of thickening agent; D, 2-5 parts of activating agent; E, 1-4 parts of softener; and F, 2-5 parts of vulcanizing agent. With the adoption of the technology provided by the invention, the producing cost is greatly reduced, and the modified vulcanized rubber powder is good in compatibility with new rubber and stable in mechanical property.

Description

technical field [0001] The invention relates to a method for comprehensive utilization of waste rubber, in particular to a process for modifying vulcanized rubber powder. Background technique [0002] As early as the 1980s, research institutions in my country have done a lot of work on the application and promotion of vulcanized rubber powder in tires. However, because the reform and opening up had just begun, people's living standards and the convenience of transportation had not been proposed for a while. High requirements, although the level of social industrialization is not high, and tires do not feel very short, so it is not surprising that the application of reclaimed rubber and its rubber powder has been neglected. 5:1), synthetic rubber is 3-4 yuan / kg, and the concept of resources is relatively weak, so the state-owned enterprises encouraged by national policies are not willing to take risks in this work, except for the active application of synthetic rubber. Invest h...
