Abstract

The present invention discloses an epoxy mortar with desirable adhesive force. The epoxy mortar comprises the following components in parts by weight: 90-140 parts of epoxy, 10-30 parts of curing agent, 20-30 parts of diethyl phthalate, 150-200 parts of cement, and 500-600 parts of silica sand. The epoxy mortar comprising the components disclosed by the present invention is excellent in adhesive performance, and has a desirable effect on repairing old building walls.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to epoxy mortar with good adhesion. Background technique [0002] Due to the age of old building walls, the skin is crispy and bubbling. Dust and dirt seal the moisture inside the masonry between the bricks and the mask. If things go on like this, physical and chemical reactions will occur between the moisture and the surface of the brick masonry, and the surface will deteriorate and rot. [0003] In order to avoid further deterioration of old building walls, its repair has become an urgent problem to be solved. As a new type of building repair material, epoxy mortar is widely used because of its good construction properties, impermeability, peeling resistance, freeze-thaw resistance, carbonization resistance, and crack resistance. Epoxy mortar usually includes epoxy resin, curing agent, cement, sand, etc., but its bonding ability is still not ideal when it is applied to the repai...
