Problems solved by technology

[0003] Adhesives for pasting mesh cloth have been listed in several varieties in recent years. One is a compound of water-based adhesives, cement and fillers. This material is cheap, but its strength is poor, its corrosion resistance is poor, and its aging resistance is poor; the other is Solvent-based unsaturated polyester adhesive, fast curing, high construction efficiency, but low strength, poor adhesion, large shrinkage rate, high toxicity, which is not conducive to indoor construction of back mesh adhesive; there is also an ordinary epoxy adhesive, As described in Application No. 201410014834.8 "A Modified Epoxy Stone Back Mesh Adhesive and Its Preparation Method", this adhesive has high bonding strength and good aging resistance, but the curing time is long, the construction efficiency is low, and the shrinkage rate is still high. large, still needs improvement
These kinds of adhesives also have a common disadvantage when used in stone back nets, that is, they are brittle and not tough enough, which leads to the fact that the stones bonded by back nets are still broken during processing.

Abstract

The invention discloses toughened environmental-friendly back mesh glue as well as a preparation method and application thereof. A component A is prepared from the following components in parts by weight: 45-65 parts of dicyclopentadiene modified unsaturated polyester resin, 25-40 parts of bisphenol-A epoxy vinyl ester resin, 10-15 parts of hyperbranched unsaturated polyester, 1-2.5 parts of a dispersant, 5-10 parts of a core-shell particle toughening agent, 25-40 parts of spherical fine silicon powder, 15-25 parts of nano calcium carbonate, 0.2-0.8 part of an accelerator and 0.02-0.08 part of a polymerization inhibitor. A component B is prepared from the following components in parts by weight: 10-70 parts of a solidifying agent, 30-40 parts of a blending agent, 30-50 parts of an inorganic filler and 3-10 parts of a stabilizer. After the component A and the component B are mixed, the solidifying agent accounts for 0.5-3.5 percent of the total weight of the mixture. The back mesh glue is small in viscosity, good in permeability, moderate in rheology and low in content of total volatile organic compounds (VOCs); and the mechanical strength, particularly the impact resistance, of a back mesh stone is remarkably superior to that of the existing product.

Description

technical field [0001] The invention belongs to the field of stone adhesives, and more specifically relates to a two-component room temperature curing and toughening environment-friendly backing adhesive and a preparation method thereof. The backing adhesive is especially suitable for reinforcing stone backings. Background technique [0002] Natural stone materials such as marble and white marble have been widely used in indoor and outdoor decoration of buildings and homes, among which the most widely used is facing stone slabs. However, high-grade natural stone resources are limited, non-renewable, and the price is becoming more and more expensive. The development of thin plate materials is inevitable; because the natural structure of stone is uneven and fragile, it is a technical measure to strengthen the back of the thin plate by pasting the back of the net. Came into being. [0003] Adhesives for pasting mesh cloth have been listed in several varieties in recent years. ...
