Problems solved by technology

[0002] The traditional two-component solvent-free polyurethane adhesive has poor thixotropy, low bonding strength, cannot be cured at room temperature, and is greatly affected by the environment. Hanging, unstable storage, greatly shorten the service life of materials in the shipbuilding, petroleum, chemical, aviation, and construction industries after use

Abstract

The invention discloses a strong adhesive, which is prepared from macromolecular synthetic latex with extremely high adhesion, special hydraulic coagulation-promoting powder and various aids according to a scientific and reasonable formula. The strong adhesive has the characteristics that a construction process is simple, and the adhesive is strongly bonded with media such as cement mortar, concrete, a stone and a ceramic material, is quickly bonded and solidified, is low in linear shrinkage, is flame-retardant, does not sag when vertically applied, and does not hurt the skin of a constructor after being contacted with the skin for a long time, and the like; and the adhesive has obvious effects of reducing the shipping weight of ship materials, improving construction performance and protecting the body of the constructor, is suitable for laying various ceramic finish materials on wet cabins such as a kitchen, a catering room and a toilet on a superstructure of a ship, and is also suitable for a civil building.

Description

technical field [0001] The invention relates to an adhesive, in particular to a strong adhesive. Background technique [0002] The traditional two-component solvent-free polyurethane adhesive has poor thixotropy, low bonding strength, cannot be cured at room temperature, is greatly affected by the environment, foams, sags, and is unstable in storage. The service life of materials in chemical, aviation and construction industries. Contents of the invention [0003] Purpose of the invention: the present invention provides a strong adhesive in order to solve the deficiencies of the prior art. [0004] The technical solution adopted in the present invention: a strong adhesive, which is formed by combining solid powder and latex, the parts by weight of each component are: 80-85 parts of solid powder, 15-20 parts of latex share. [0005] As a preference, the solid powder is composed of 42.5 grade Portland cement, SN-II water reducing agent, fly ash and diatomaceous earth; th...
