Embodiment 1

[0034] A kind of regenerated butyl rubber, comprising: rubber powder 1000g, rapeseed oil 15g, cottonseed oil 15g, rubber seed oil 20g, stearic acid 1g.

[0035] The particle size of the rubber powder in this embodiment is 0-0.2mm.

[0036] Above-mentioned regenerated butyl rubber is prepared by following steps:

[0037] S1. Rinse the waste butyl inner tube and put it into the soaking tank, heat it to 110°C, soak in the soaking solution for 2 hours, so that the butyl inner tube decomposes and releases harmful substances, and at the same time, use a biochemical absorption tower to purify the harmful gas;

[0038] S2. Crush the above-mentioned treated butyl inner tube into rubber powder after ultra-low temperature freezing, and select a 5-mesh sieve to sieve the crushed inner tube. The freezing temperature is -50 to -45°C;

Abstract

The invention belongs to the technical field of inner tire production, and concretely relates to environment-friendly type inner tire and a production method thereof. The environment-friendly type inner tire comprises the following components in parts by weight: 30-70 parts of natural rubber, 30-70 parts of reclaimed butyl rubber, 35-50 parts of carbon black, 5-15 parts of white carbon black, 1-7parts of active calcium carbonate, 1-9 parts of an antioxidant, 1.5-2.5 parts of a vulcanizing agent, and 1-4 parts of a vulcanization accelerator. The inner tire has the advantages of excellent wearresistance, good airtightness, high aging resistance performance, and good heat resistance, polycyclic aromatic hydrocarbons are used in the whole production process, the inner tire accords with requirements of environmental protection, and the inner tire is suitable for industrial large scale promotion and application.

Description

technical field [0001] The invention belongs to the technical field of inner tube production, and in particular relates to an environment-friendly inner tube and a production method thereof. Background technique [0002] The inner tube is an air-bearing container for inflation and vibration reduction. It is used as an auxiliary air-bearing container for the inner cavity of the tires of trucks, motorcycles, bicycles, and rickshaws. According to the main materials contained, it can be divided into natural rubber inner tubes and butyl rubber inner tubes. The natural rubber inner tube is mainly made of rubber hydrocarbon, which has high elasticity, high elongation strength, excellent tear resistance and abrasion resistance, and is superior to most synthetic rubbers in terms of comprehensive performance, but it is easy to age and deteriorate, and its heat resistance is not good. Butyl rubber is a copolymer of isobutylene and a small amount of isoprene or butadiene, which has good...
