Rubber hydrocarbon is one of the basic components of natural rubber or its latex. The content of rubber hydrocarbon refers to the rubber hydrocarbon in rubber, mortar, reclaimed rubber or rubber. The rubber in the rubber reclaim refers to the elasticity Rubber composition. Reclaimed rubber products, each year a large number of tire reclaimed rubber for a variety of rubber products, is the most commonly used types of reclaimed rubber, tire reclaimed rubber hydrocarbon content is how much? And it with rubber products in the amount of what?
Japanese Industrial Standard JIS K6313 made the following reckoning on the rubber content of reclaimed rubber: 45% -50% of the rubber hydrocarbon of reclaimed rubber tire (55% of reclaimed rubber in automobile tire rubber; Hydrocarbon content of 30% to 40%, we will not discuss for the time being), while the physical and mechanical properties of reclaimed rubber tire vulcanizate performance is only 50% to 60%. Therefore, 100 parts of reclaimed rubber containing about 50 parts of rubber, equivalent to 30% of the performance of the original vulcanizates, which means that 100 parts of the reclaimed rubber can only be used instead of 30 parts of raw rubber, the formula is: 70 parts of raw rubber +100 Tire tread rubber = 100 copies of raw rubber!
The use of tire reclaimed rubber production of rubber products Reclaimed rubber product recipes, tire reclaimed rubber dosage according to its rubber hydrocarbon content and vulcanizing agent performance equal replacement, tire reclaimed rubber is usually used instead of 30% raw rubber, that is, 100 tires Reclaimed rubber can replace 30 parts of raw rubber. The use of tire reclaimed rubber production of rubber products, the tire reclaimed rubber and natural rubber, styrene butadiene rubber, butadiene rubber and other rubber used to reduce rubber production costs and improve overall quality performance.
The vulcanizing agent, accelerator, activator, antioxidant, filler and softener in tire reclaimed rubber product formula are all calculated on the basis of rubber hydrocarbon content, and the reclaimed rubber component itself is regarded as filler and softener. For example, when 100 parts of reclaimed rubber and 100 parts of natural rubber are used in combination, the total amount of compounding formula in the formula is X, and the formula is (100 + 100 × 30%) × × 100% = 40% All with the amount of X = 325, the amount of other compounds in accordance with the amount of plastic were calculated.
When the tire reclaimed rubber products are formulated, the above formula can be used as a basic calculation method. The specific amount of each compounding agent in the formula needs to be timely adjusted according to the tire reclaimed rubber index, rubber product demand, climate change, etc. Mass production.
