Embodiment 1

[0021] A method for manufacturing a weather-resistant rubber, the specific steps are:

[0022] (1) Add rubber raw materials, including vulcanized rubber particles, silicone resin and auxiliary agents, to the pre-reforming reactor, and

[0023] Polymerize to form rubber-packed vulcanized rubber; the polymerization proceeds until the conversion rate is 80% of the phase inversion starting point of the formed vulcanized rubber particle-organic silicon resin-colloidal vulcanized rubber mixture; : 80%, 10%, 10%; and the components of the auxiliary agent and the mass percentages of each component are: compatibilizer: 65%, plasticizer: 10%, stabilizer: 20%, white oil: 5% %;

[0024] (2) separating the mixture formed in step (1) to generate a first stream comprising 75wt% of the mixture in step (1) and a second stream comprising the remainder of the mixture formed in step (1);

[0025] (3) adding the first stream to the second reactor for further polymerization of vulcanized rubber p...

Embodiment 2

[0031] A method for manufacturing a weather-resistant rubber, the specific steps are:

[0032] (1) Add rubber raw materials, including vulcanized rubber particles, silicone resin and auxiliary agents, to the pre-reforming reactor, and

[0033] Polymerize to form rubber vulcanized rubber; the polymerization proceeds until the conversion rate is 86% of the phase inversion starting point of the formed vulcanized rubber particle-organic silicon resin-colloidal vulcanized rubber mixture; : 88%, 7%, 5%; and the components of the auxiliary agent and the mass percentages of each component are: compatibilizer: 70%, plasticizer: 10%, stabilizer: 10%, white oil: 10% %;

[0034] (2) separating the mixture formed in step (1) to generate a first stream comprising 82 wt% of the mixture in step (1) and a second stream comprising the remainder of the mixture formed in step (1);

[0035] (3) adding the first stream to the second reactor for further polymerization of vulcanized rubber particle...

Abstract

The invention provides a preparation method of rubber with strong weather resistance. The preparation method specifically comprises the following steps: preparing a mixture containing vulcanized rubber particles and organic silicon resin; dividing the mixture into a first material flow and a second material flow; carrying out phase inversion on the first material flow, mixing with the second material flow, and carrying out phase inversion to form a vulcanized rubber body; adding inorganic powder and a functional auxiliary into melt glue; and extruding. The preparation method provided by the invention is simple in process and strong in controllability of preparation process. The rubber prepared by the method provided by the invention has extremely strong waterproofness and weather resistance and is strong in practicality.

Description

technical field [0001] The invention belongs to the field of sports equipment, and in particular relates to a method for manufacturing a rubber with strong weather resistance. Background technique [0002] Table tennis is our country's national sport, and our country is also a strong table tennis country, with world champions emerging in large numbers. Table tennis is very popular in our country, no matter where you can see table tennis halls and table tennis fans. For the north where the weather is cold, in order to prevent the rubber from cracking and warping due to freezing, technicians have developed low-temperature-resistant rubber; while for the south where the weather is hotter, technicians have developed high-temperature-resistant rubber to prevent melting and degumming. However, these two rubbers can only be used in specific regions and have limitations. [0003] Therefore, it is a difficult problem that those skilled in the art urgently need to solve to devel...
