Bathroom floor tile adhesive, preparation method and application in anti-leakage construction

Abstract

The invention relates to a toilet floor tile adhesive, and belongs to the field of adhesive. The toilet floor tile adhesive comprises hyaluronic acid and a peptide compound, and the preparation methodcomprises the steps: (1) preparing a 2-4 wt% hyaluronic acid aqueous solution; (2) preparing a 10-30 wt% peptide compound aqueous solution; (3) mixing the hyaluronic acid aqueous solution and the peptide compound aqueous solution with equal volume to obtain a mixed solution; and (4) adding a photoinitiator and irradiating with ultraviolet light for 2-5 min, and thus obtaining the adhesive. The photoinitiator is preferred to be benzophenone compounds or benzoin derivatives. The toilet floor tile adhesive provided by the invention has good bonding strength, the original strength is as high as 1.57 MPa, and the strength can be improved to 1.75 MPa to a certain extent after the adhesive is soaked in water.

Description

technical field [0001] The invention belongs to the field of adhesives, in particular to an adhesive for bathroom floor tiles. Background technique [0002] In daily life, the bathroom is a place with a large water consumption and high water frequency, and water seepage in the bathroom is relatively common. The common problem of toilet leakage has become the main object of homeowners’ complaints about housing quality, seriously affecting the normal life of residents, not only easily causing neighborhood disputes, but also causing the safety of building structures to be returned and shortening the service life of buildings. [0003] In the anti-leakage construction process of the bathroom, the most important thing is the choice of waterproof coating and tile adhesive. Both of them use materials with better performance, which can not only waterproof but also have high tile adhesion As time goes by or the humidity of the environment changes, the degree of adhesion is reduced a...

Problems solved by technology

[0006] However, in the prior art, there is hardly any report using hydrogel as a floor tile adhesive, and most of them are still traditional cement mortar adhesives, such as a high-strength hydrogel provided by the Chinese patent of CN 104150849 A. The main component of adhesive is silicate clinker and fly ash; Another example is that the main raw material of the waterproof color caulking adhesive for construction provided by the Chinese patent of CN 100558840 C is also cement and quartz sand
