Problems solved by technology

[0004] In order to solve the problem of ceramic glue in the prior art, after construction, it has high density, small porosity, relatively hard after setting, relatively high strength, and high elastic modulus, so the shock absorption effect is weak; once people use ceramic glue When walking on the bonded ceramic tiles, the friction sound between shoes and tile surface and the impact sound of high heels and tile surface will be relatively loud, which is easy to generate noise. Affecting problems such as the quietness of public places, the object of the present invention is to provide a kind of cement-based adhesive

Abstract

The invention discloses a cement-based adhesive which consists of an inorganic gel, elasticity modulus filler, sand and a dry-mixed mortar additive, wherein the mass percentages of the various components in the adhesive are as follows: 35-45% of inorganic gel, 15-30% of elasticity modulus filler, 17-47% of sand, 3-8% of dry-mixed mortar additive and the balance of water. The cement-based adhesive disclosed by the invention has the following beneficial effects that by adding the low elasticity modulus filler which has the advantages of good elasticity, shock-proofing, sound insulation and the like, the cement-based adhesive has the characteristics of shock absorbing, noise reduction and the like, so that a problem of noise generated from the collision of ceramic tiles in a public place is relieved; in addition, the cement-based adhesive provided by the invention also solves the problems of low compressive strength, low bonding strength and the like of the adhesive after the low-modulus filler is added; shearing strength on the interfaces of the ceramic tiles caused by heat expansion and cold contraction is reduced and the bonding durability of the ceramic tiles on the basis of shock absorbing and noise reduction is improved; therefore, the cement-based adhesive is quite high in promotional value.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a cement-based binder. Background technique [0002] With the continuous improvement of people's living standards, people have higher and higher requirements for the sound insulation effect of the floors of residential houses and public places. In order to meet people's requirements, the floor construction technology of many residential houses and public places is still being continuously improved. middle. [0003] At present, the floors of buildings on the market mostly use marble or ceramic tiles, mainly because marble and ceramic tiles are easy to clean, stain-resistant, waterproof, anti-corrosion, and wear-resistant, so they are widely used in civil buildings, large shopping malls, and office buildings. And the ground decoration of public places such as hospitals, when the marble or ceramic tiles are being constructed, use ceramic glue to bond the marble or cerami...
