Abstract

The invention discloses a novel marble adhesive. The novel marble adhesive comprises the following raw materials in parts by weight: 15-35 parts of a polyurethane prepolymer, 12-25 parts of Portland cement, 8-17 parts of epoxy resin, 9-18 parts of unsaturated dianhydride, 7-16 parts of micron-sized silicon dioxide, 10-20 parts of redispersible latex powder, 1-3 parts of oxidized castor oil, 2-4 parts of a curing agent, 0.8-1.9 parts of an alkalization inhibitor, 1-5 parts of a thixotropic agent, 1-3 parts of an anti-ultraviolet absorbent, 0.3-0.6 part of starch ether, 0.3-0.6 part of cellulose ether and 5-25 parts of a filler. The novel marble adhesive is high in adhesive strength and free of alkalization and whitening, has better water resistance, freezing resistance and aging resistance than those in the prior art, and is long in service life.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a novel marble glue and a preparation method thereof. Background technique [0002] The traditional method of installing marble on the wall is to punch a number of holes on the wall (a piece of marble generally has four holes), then drive in expansion screws, and then cut four grooves on the marble to lock these wire ropes, and then use The steel wire rope locks the marble with the expansion screw, adds the filler, and then joints. However, after a period of time, the expansion screws and wire ropes are prone to aging or corrosion and rust, which may cause the marble to fall, which poses a great safety hazard, and some will return to alkali and spit white. Contents of the invention [0003] The present invention provides a new type of marble glue and its preparation method, which solves the above-mentioned deficiencies in the background technology. The new type of...
