Problems solved by technology

This kind of adhesive still has deficiencies, one is to use active calcium carbonate powder as inorganic filler, the oil absorption value is higher, easy to thicken, which restricts the amount of filler used, adding solvent ethanol, it is difficult for small molecules to escape during curing, and the other is The use of phenalkamine curing agent will cause serious yellowing and discoloration, and it is easy to contaminate materials. The third is the plasticization of dibutyl phthalate, which affects the bonding strength. It does not meet environmental protection requirements, and the plasticizing effect is difficult to last. It is indeed necessary to improve

Abstract

The invention relates to a bi-component modified epoxy adhesive for compounding a marble veneer with base materials such as a marble slab, a granite slab, a porcelain slab and a preparation method thereof. The adhesive comprises a component A and a component B, wherein the component A is prepared from epoxy resin, polyether, torispherical silicon micro-powder, heavy calcium carbonate and an auxiliary agent; and the component B is prepared from homemade modified amine, polyether amine, the torispherical silicon micro-powder, the heavy calcium carbonate and the auxiliary agent. The product has the characteristics of room temperature curing, high bond strength, water, heat and freeze-thaw resistance, low cost, convenient construction and the like.

Description

technical field [0001] The present invention relates to a kind of modified epoxy adhesive used for compounding facing stone thin boards, in particular to a kind of modified epoxy adhesive for compounding which takes marble thin boards as panels and marble boards, granite boards and porcelain boards as base materials and its Preparation. Background technique [0002] Marble slabs are elegant in texture, with clear and beautiful textures, and are often used as decorative materials for interior and exterior walls, floors, ceilings, window sills, tabletops, and sanitary ware of buildings. With the improvement of people's living standards and the promotion of cultural literacy, the number of such decorative materials is increasing. However, the marble material is brittle, the plate has many cracks, and the strength is not high. The thickness of the plate is generally not less than 20mm, which increases the consumption of marble materials, especially precious marble materials, an...
