Embodiment 1

[0014] (1) Preparation of banbury rubber: crush 110g of waste rubber and preheat it in the screw conveyor, then weigh 30g of softener and mix it, and add 32g of softener and 20g of activation to the kneading chamber The agent is rotated, stirred and sheared, and then introduced into a hot oil temperature of 220°C for banburying treatment to obtain banbury rubber.

[0015] (2) Preparation of rubber powder: Mix the above-mentioned banbury rubber with 30 parts of EPDM rubber, 7 parts of zinc oxide, 8 parts of magnesium oxide, 5 parts of titanium dioxide, 13 parts of carbon black, and 10 parts of dicumyl peroxide , 12 parts of boric acid, 6 parts of dioctyl fat, and 5 parts of sulfur are placed in a mixer and stirred evenly to obtain rubber powder.

[0016] (3) Preparation of glue A: Press the stirred rubber powder into a twin-screw extrusion device through a forced feeding device for rapid rotation and chain breaking at a rotation speed of 110 rpm to prepare glue A.

Abstract

The invention discloses a recycled butyl flame-retarding rubber preparing technology, and relates to the technical field of rubber material preparation. The recycled butyl flame-retarding rubber preparing technology comprises four processing steps of preparing banburying rubber, preparing rubber powder, preparing A rubber and forming a product. The recycled butyl flame-retarding rubber preparing technology has the advantages that a recycled butyl flame-retarding rubber processing process is easy and convenient to conduct, the produced product is good in quality and high in wear resistance, the production cost is saved, a made engine rubber pad is better in elasticity and toughness, the vibration reduction and noise reduction functions can be improved, the service life of the rubber pad is prolonged, bubbling is not likely to happen in the processing process, certain fragrant flavor is emitted, and the sealing performance is good.

Description

technical field [0001] The invention relates to the technical field of rubber material preparation, in particular to a preparation process of regenerated butyl flame-retardant rubber. Background technique [0002] Under the harsh environment of the current social competition, since rubber is a recyclable resource, the secondary development and utilization needs to go through various treatment processes to achieve the effect that new products can achieve, which will inevitably make this process very difficult. For enterprises, how to study a processing technology of renewable rubber determines the competitiveness of the enterprise's products. There are thousands of formulas and manufacturing methods for rubber compositions, and different material formulas are often provided according to different use requirements. The common general components commonly used at present with weather resistance and wear resistance are nitrile rubber 100, N330 carbon black 65, dibutyl fat 20, su...
