Wall brick stacking adhesive and production technology thereof

Abstract

The invention discloses a wall brick stacking adhesive and a production technology thereof. The adhesive can be widely applied to stacking and adhering of wall bricks of concrete walls, foamed ceramicwalls, magnesium silicate walls, foamed cement composite strip boards and EPS (Expanded Polystyrene) composite strip boards, and the volume of the adhesive is increased by 10 to 30 times in a curingprocess; the adhesive has elasticity and can overcome cold shrinkage and thermal expansion rates of different base materials; the adhesive can permeate into micro-pores of the wall bricks so that theadhesive is in sufficient contact with the wall bricks and the shearing force reaches 3 to 6 MPA; the adhesion force is strong and free retraction between the wall bricks can be limited; the cold shrinkage and thermal expansion of the wall bricks are balanced in the bricks and the cracking of the wall bricks is reduced; meanwhile, when the adhesive is cured, the adhesive reacts with moisture in the air to be cured, and a solvent and formaldehyde do not exist, so that the adhesive is relatively environmentally friendly; the dosage of the adhesive is small, field construction stirring is not needed and a production and manufacturing technology is simple.

Description

technical field [0001] The invention belongs to the technical field of adhesive for wall bricks, and in particular relates to an adhesive for stacking and pasting wall bricks which can effectively reduce the cracking of wall bricks during pasting and ensure a firmer paste between wall bricks and its adhesive. Production Process. Background technique [0002] At present, when the wall bricks of concrete walls, foamed ceramic walls, magnesium silicate walls, foamed cement composite strips and EPS composite strips are stacked and pasted into walls, the wall bricks are realized by concrete or ordinary tile paste glue. For those pasted between, the volume of concrete or ordinary tile adhesive will decrease after curing, and the amount of free expansion and contraction between wall tiles will be large, which will cause cracking problems in wall tiles. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention aims to provide a method t...
