Production process of rubber-asphalt paint

Abstract

The rubber-asphalt paint consists of petroleum asphalt 70-95 wt%, rubber powder 5-30 wt%, fermenting agent 0.1-0.3 wt%, zinc oxide 0.1-0.2 wt% and sulfur powder 0.1-0.2 wt%. It is produced through heating petroleum asphalt to liquefy and eliminating impurity, adding rubber powder at 180-250 deg.c while stirring, cooling to solidify and cutting into blocks. The present invention has the advantages of no environmental pollution, coating with elasticity, high ageing resistance, high corrosion resistance, long life and bright surface.

Description

technical field [0001] The invention belongs to a manufacturing process of anti-corrosion and waterproof rubber asphalt paint. Background technique [0002] The current general-purpose rubber asphalt coatings need to add more than 40% organic solvents such as xylene, turpentine or solvent gasoline, etc., in order to fully blend the rubber and asphalt. Its disadvantage is that it cannot be recycled during the spraying process, which increases the cost, and causes energy waste and environmental pollution. Contents of the invention [0003] The invention provides a manufacturing process of rubber asphalt paint, which can completely use no organic solvent, and solves the problems of energy waste, environmental pollution and high cost in the prior art. Technical scheme of the present invention is: [0004] According to the following formula (percentage by weight) [0005] Petroleum asphalt 70~95% [0006] Rubber powder 5~30% [0007] Starter 0.1~0.3...
