Method for manufacturing antibacterial composite films

Abstract

The invention relates to a method for manufacturing antibacterial composite films. The method includes cleaning waste rubber, removing impurities in the waste rubber, preparing catalysts, and carrying out primary pyrolysis, secondary pyrolysis procedures and the like on the waste rubber to obtain products; mixing a plurality of auxiliaries with the pyrolysis products to obtain mixtures; processing rubber products by the aid of the mixtures. The method has the advantages that the waste rubber is subjected to two-stage pyrolysis by the aid of the catalysts, the temperatures and the pyrolysis time are strictly controlled at each pyrolysis stage, accordingly, sufficient pyrolysis can be guaranteed, internal coking of equipment due to excessively high temperatures can be prevented, and influence on the quality of the pyrolysis products can be prevented; the diversified auxiliaries are directly added into the products, so that the novel rubber products can be manufactured, effects of recycling waste can be realized, environments can be protected, and resources can be saved.

Description

technical field [0001] The invention relates to a preparation method of an antibacterial composite film. Background technique [0002] As we all know, rubber is being used more and more widely in various industries because of its excellent high temperature resistance, low temperature resistance, corrosion resistance, electrical insulation, non-toxicity, flame retardancy, and stable chemical properties. The waste rubber is cracked and put into the production of rubber products through further processing, which not only handles a large amount of industrial waste such as waste rubber produced in modern society, reduces environmental pollution, but also provides a new way to solve the increasingly serious energy crisis . At present, although various processes and equipment related to the cracking of waste rubber have been reported, most of them use high cracking temperature in order to ensure that the cracking of waste rubber is sufficient, so that the final cracking produces m...

Problems solved by technology

At present, although various processes and equipment related to the cracking of waste rubber have been reported, most of them use high cracking temperature in order to ensure that the cracking of waste rubber is sufficient, so that the final cracking produces more combustible gas and oil. If the cracking temperature is low, the oil yield will be low, and high-temperature cracking will easily cause coking inside the equipment, shorten the service life, and increase production energy consumption; if the cracking temperature is lowered, the cracking will not be complete, and there will be more impurities attached to the obtained carbon black, making the carbon black drop in quality
