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.
