Abstract

The formula and production process of the water-based environmentally friendly stone backing glue of the present invention can effectively solve the problems of easy aging, hollowing, detachment, environmental pollution, harm to human health and the like caused by the traditional unsaturated resin backing technology. The formula and production process of the present invention are mainly made by the following steps: A, take the polymer emulsion that is 15.0~40.0 parts by weight, the water that is 10.0~30.0 parts by weight, the water by weight that any one of claims 1~7 takes 0.1 to 3.0 parts of preservative, 0.1 to 5.0 parts by weight of crosslinking agent and 0.5 to 5.0 parts by weight of film-forming agent are mixed, and stirred at a speed of 300 to 500 r / min; B, claim 1 is taken successively Any one of the parts by weight in ~7 is 15.0 to 35.0 parts by weight of quartz powder or quartz sand, 20.0 to 50.0 parts by weight of heavy calcium powder, 2.0 to 10.0 parts by weight of titanium dioxide or Taibai pulp, and 2.0 parts by weight ~10.0 kaolin or mica powder, put into the mixture in step A, after mixing, stir at a speed of 1300~1500r / min, and continue to disperse for 30~60min; C. Get a uniform viscous slurry, which is water-based environmental protection stone Net glue.

Description

technical field [0001] The invention relates to the field of stone processing, in particular to a formula and a production process of a water-based environmental-friendly stone back mesh adhesive. Background technique [0002] Stone is a high-grade building decoration material, which is widely used. Stones with a thickness of less than 3cm are cracked and fragile products. The stone material increases the back mesh glue. [0003] Unsaturated resin back-mesh glue is a kind of special back-mesh technology glue in the field of stone processing. When using it, first spread the grid cloth on the back of the stone surface, and then apply the back-mesh glue evenly on the mesh cloth, so that It is a kind of stone back mesh technology in which stone and grid cloth are bonded and fixed. [0004] The above technology mainly utilizes the toughness of the grid cloth and the characteristics of plane tensile stiffness, and then sticks the cracked and fragile stone and the grid cloth toge...
