Abstract

The invention discloses an environmental friendly high-strength adhesive for a building crack and a preparation method thereof. The environment friendly high-strength adhesive comprises the following components by mass percent: 69-73 percent of waterborne epoxy emulsion, 19-25 percent of triallylamine waterborne curing agent, 2-6 percent of superfine cement (DMFC-GM), 0.15-0.2 percent of dioctyl phthalate (DOP), 0.1-0.2 percent of sterilizing agent KS25 and 2.6-5.73 percent of tap water. The adhesive disclosed by the invention has the advantages that the content of the volatile organic compounds is low, no methyl aldehyde exists, the non-toxic and environmental friendly effects are achieved, the bonding strength, compressive strength, and tensile strength are high, the adhesion stress is strong, the surface drying time is short, the cost is low, the process is simple, and the construction is convenient by using the adhesive, so that the environmental friendly high-strength adhesive is a novel environmental friendly high-strength adhesive for the building crack, and an ideal substitute for the traditional normal adhesive for the building crack.

Description

technical field [0001] The invention belongs to the technical field of adhesives, and relates to an environment-friendly high-strength adhesive used for cracks in buildings and a preparation method thereof, which is mainly used in the maintenance of cracks in buildings. Background technique [0002] In recent years, with the development of building construction in my country, people have higher and higher requirements for the quality of building construction. However, due to the influence of construction and other adverse factors, hidden dangers are buried for later use, and phenomena such as width cracks appear, which affect normal use. . However, traditional repairs use solvent-based adhesives to fill gaps and repairs. Solvent emissions seriously pollute the environment and endanger human health. For the health of the people, in order to prevent pollution, in line with the principle of ensuring safety and taking economic and environmental protection into account, we have d...
