Water-soluble gutter oil environment-friendly asphalt separant

Abstract

The invention discloses a water-soluble gutter oil environment-friendly asphalt separant which comprises the following raw materials in parts by weight: 100-200 parts of deionized water, 20-40 parts of gutter oil, 5-15 parts of glycerol, 5-8 parts of dimethyl silicone oil, 8-10 parts of Tween 80, 10-12 parts of span 60, 1-3 parts of an antirust agent, 3-5 parts of talcum powder, 0.6-1 part of sodium benzoate and 20-30 parts of polyvinyl alcohol with the mass fraction of 10%. The water-soluble gutter oil environment-friendly asphalt separant is prepared by the following steps: 1, mixing the deionized water, gutter oil, glycerol, dimethyl silicone oil, Tween 80 and Span 60 to obtain a first mixed solution; 2, conveying the antirust agent, talcum powder, sodium benzoate, polyvinyl alcohol with the mass fraction of 10% and the first mixed solution into a colloid mill emulsifying machine to obtain a second mixed solution; and 3, adjusting the pH value of the obtained second mixed solution to 7 to obtain the asphalt pavement roller separant.

Description

technical field [0001] The invention belongs to the technical field of asphalt release agents, in particular to a water-soluble waste oil environment-friendly asphalt release agent. Background technique [0002] In the construction of asphalt pavement, since the asphalt mixture (mixed with asphalt and mineral materials at high temperature) must be paved at a high temperature of 110-130 ° C, the paving contact parts of the paving equipment, rolling The parts that are in direct contact with equipment, transportation tools, auxiliary small tools, etc. are attached to the surface due to temperature changes, which is not conducive to operation and cleaning problems. [0003] Gasoline and diesel are currently used for processing, which is costly and unsafe to use, which is unfavorable to asphalt mixture, causing pollution and destroying the road surface; adopting vegetable oil (waste oil) is not conducive to environmental protection and wastes resources.

Problems solved by technology

[0002] In the construction of asphalt pavement, since the asphalt mixture (mixed with asphalt and mineral materials at high temperature) must be paved at a high temperature of 110-130°C, the paving contact parts of the paving equipment, rolling Equipment, transportation tools, auxiliary small tools and other direct contact parts are attached to the surface due to temperature changes, which is not conducive to operation and cleaning problems

[0003] Gasoline and diesel are currently used, which is costly and unsafe to use, which is unfavorable to the asphalt mixture, causing pollution and destroying the road surface; using vegetable oil (waste oil) is not conducive to environmental protection and wastes resources. The present invention uses a small amount of waste oil to save costs.

The characteristic of water-soluble asphalt release agent is that it is easy to wash, but the disadvantage is that it is highly corrosive to steel molds
