Problems solved by technology

[0003] The present invention mainly solves the technical problems of raw material cost, high specific gravity, high Mooney viscosity and low extrusion rate in the prior art, thereby increasing product production speed and decreasing production efficiency; The rubber content of the rubber reduces the amount of expensive characteristic rubber while ensuring the product quality, thereby greatly reducing the cost of raw materials; the specific gravity accelerates the mixing speed, accelerates the release of air bubbles and blisters, and the characteristics of processing aids enable production. The preparation method of an airtightness enhancer that reduces the Mooney viscosity, increases the extrusion rate, improves the product production speed and production efficiency, and reduces the production cost again from the production process

Embodiment

[0021] A kind of preparation method of airtightness enhancer is characterized in that, comprises the following steps:

[0022] Step 1, adding short fiber, asphalt, silicon, alumina powder to the coal powder for proportioning and mixing, wherein, the quantity ratio of adding short fiber is 15% of the input amount of the material; the mass proportion of the material is: asphalt 10%, silicon 5%, alumina powder 5%, coal powder 80%. The order of adding ingredients to coal powder is: asphalt, alumina powder, silicon, and the specific steps of mixing are as follows:

[0023] Step 2.1, add bitumen to coal powder, stir for 1 minute;

[0024] Step 2.2, adding alumina powder to the mixed material in step 2.1 and stirring for 1 minute;

[0025] Step 2.3 Add silicon to the mixture completed in step 2.2 and stir for 1 minute.

[0026] Step 2, putting the mixture that has been metered and mixed in step 1 into a fine powder machine for pulverization and grinding, and then vibrating and sie...

Abstract

The invention relates to a method for preparing a promoter, in particular to a method for preparing an air-tight promoter. The method for preparing the air-tight promoter is characterized by comprising the following steps of: 1, adding short fibers, asphalt, silicon and alumina powder into coal powder, proportioning and mixing, wherein the adding amount of the short fibers is in an amount which is 15 percent based on the input amount of materials; 2, adding a mixture which is metered and mixed in the step 1 into a pulverizing mill for grinding, and performing vibration sieving purification by using a screen sieve; and 3, adding treated distillate aromatic extract (TDAE) into the mixture obtained in the step 2, putting into a mixing machine at the temperature of between 40 and 45 DEG C, rotating and mixing for 1 to 10 minutes, and discharging. The method has the advantages that: the content of rubber in butyl rubber is reduced, specific gravity is low, Mooney viscosity is reduced, and extrusion rate is improved, so that the production speed and the production efficiency of a product are increased; and return rate is reduced, namely product yield is improved.
