Problems solved by technology

[0002] The existing method of refining diesel from heavy oil is to use sulfuric acid as a degradation agent to degrade the heavy oil. After obtaining diesel oil, what remains is a highly acidic and high-viscosity acid residue with a sulfur content of 20%. The main component of this acid residue is It is a random multi-polymer copolymer. If the acid residue is not handled properly, it will pollute the environment.

Embodiment Construction

[0006] Now in conjunction with embodiment the present invention is described in further detail:

[0007] The present invention is achieved in this way, and the manufacture method of the waterproof leak-trapping adhesive of the present invention is achieved in this way, adding calcium hydroxide to the acid slag to obtain the acid slag depolymerization paste, and using benzene solvent or acetate The solvent dissolves the waste polymer foam into a viscous liquid, and then mixes the acid slag depolymerization paste with the viscous liquid to obtain a waterproof leak-trapping adhesive, wherein the weight ratio of acid slag to calcium hydroxide is 1: 0.6-1:1, the content of waste polymer foam in the viscous liquid is 20-50g / 100ml, and the weight ratio of the acid slag depolymerization paste to the viscous liquid is 1:0.2-1:1.

[0008] Here, the benzene-based solvent is benzene, and the acetate-based solvent is n-butyl acetate or isobutyl acetate or thinner.

Abstract

The production process of waterproof leakage-repairing adhesive features that calcium hydroxide is added into acid sludge to obtain the depolymerizing acid sludge paste, waste polymer foam is dissolved with benzene or acetate solvent to obtain ropy liquid, and the depolymerizing acid sludge paste and the ropy liquid are then mixed to form the waterproof leakage-repairing adhesive. It has acid sludge / calcium hydroxide weight ratio of 1-1.67, waste polymer foam content in the ropy liquid of 20-50 wt%, and the weight ratio between the depolymerizing acid sludge paste and the ropy liquid of 1-5. The present invention has the advantages of best utilization of acid sludge, environment friendship, low production cost and good product use effect.

Description

Technical field: [0001] The invention relates to a building material, in particular to a waterproof leak-trapping adhesive and a manufacturing method thereof. Background technique: [0002] The existing method of refining diesel from heavy oil is to use sulfuric acid as a degradation agent to degrade the heavy oil. After obtaining diesel oil, what remains is a highly acidic and high-viscosity acid residue with a sulfur content of 20%. The main component of this acid residue is It is a random multi-polymer copolymer. If the acid slag is not handled properly, it will pollute the environment. Invention content: [0003] The object of the present invention is to provide a method for manufacturing a waterproof leak-trapping adhesive that can fully reuse acid slag, does not pollute the environment, and has low manufacturing cost. [0004] The manufacture method of the waterproof leak-trapping adhesive of the present invention is realized in this way, adding calcium hydroxide to...
