Abstract
The present invention relates to a kind of preparation methods of rubber slab, and waste Crumb rubber is broken into the rubber powder lower than 60 mesh, are then dried at 105 DEG C, and vulcanization accelerator, vulcanizing activator, sulphur and vulcanizing agent is then added, vulcanized after mixing to get；It is in terms of 100% by the rubber powder after drying, vulcanization accelerator dosage is 0.3-0.5%, and vulcanizing activator dosage is 2.5-3.5%, sulfur consumption 3-5%, vulcanizing agent 0.5-0.8%.Preparation process is simple, the pollution of waste water, exhaust gas, dust is not present convenient for operation, and in technical process.Rubber slab obtained has mechanical strength height, resistance to ag(e)ing good.
Description
Technical field
The present invention relates to a kind of preparation methods of rubber slab, belong to rubber product technical field.
Background technique
Waste old is one kind of solid waste, and main source is some rubber products, such as the inner tube of a tyre, the sebific duct of various vehicles
With the discarded and plant produced leftover pieces of adhesive tape and rubber overshoes etc..Waste old is passed through into the side such as ambient ground or low-temperature grinding
Method is used after preparing rubber powder, is a kind of very important approach of current waste old recycling.Usually i.e. by scrap rubber
Through crushing, desulfurization, the processes such as refining are rolled, the sulphur in scrap rubber is thoroughly removed, restore the due elasticity and plasticity of rubber, thus shape
At reclaimed rubber.The method is in the presence of energy consumption is high, the long disadvantage of low efficiency, process flow, and in view of current technology and economic condition
It being limited, the scrap rubber of many reclaimed rubber enterprises, China takes off sulphur regeneration process and there is different degrees of low-concentration organic exhaust gas,
It is easy to cause atmosphere pollution.
Summary of the invention
Present invention aims to solve the deficiencies of the prior art, and provides a kind of a kind of preparation methods of rubber slab.
Technical solution
A kind of preparation method of rubber slab: being broken into the rubber powder lower than 60 mesh for waste Crumb rubber, is then dried at 105 DEG C, so
Vulcanization accelerator, vulcanizing activator, sulphur and vulcanizing agent are added afterwards, vulcanized after mixing to get；With the glue after drying
Powder be 100% meter, vulcanization accelerator dosage be 0.3-0.5%, vulcanizing activator dosage be 2.5-3.5%, sulfur consumption 3-5%,
Vulcanizing agent 0.5-0.8%.
Further, the vulcanizing activator is the mixture of magnesia and zinc oxide 1:1.
Further, curing temperature is 125~145 DEG C, and pressure is 6~8Mpa, time 15-20min.
Preparation process of the invention is simple, the dirt of waste water, exhaust gas, dust is not present convenient for operation, and in technical process
Dye.Rubber slab obtained has mechanical strength height, resistance to ag(e)ing good.
Specific embodiment
The present invention is further explained in the light of specific embodiments.
Embodiment 1
60 mesh rubber powders are made in scrap rubber crushing, rubber powder is dried in 105 DEG C, following component is weighed by weight and mixes
It is uniform: 100 parts of rubber powder, 0.4 part of vulcanization accelerator, 4 parts of vulcanizing activator (mixture of magnesia and zinc oxide 1:1), sulphur 3
Part, 0.6 part of vulcanizing agent, mold is filled this blend into, under conditions of temperature is 140 DEG C, pressure is 7MPa, vulcanizes 18min.
Claims (3)
