Abstract

The invention discloses an adhesive for an assembly type toilet ground waterproof bottom box and a preparation method of the adhesive. The adhesive for the assembly type toilet ground waterproof bottom box comprises a main agent and a curing agent, and the main agent comprises the following components in parts by weight: 10-30 parts of polyether polyol, 10-30 parts of polyester polyol, 40-80 parts of an inorganic filler, 3-5 parts of tackifying resin, 1-5 parts of a water removal agent, 1-3 parts of a coupling agent and 0.1-1 part of a dispersing agent. And the curing agent is an isocyanate prepolymer with the NCO group content of 20-21%. The adhesive disclosed by the invention can form 100% cohesive failure on the surface of an ABS (Acrylonitrile Butadiene Styrene) base material after being cured for 7 days in a standard environment, and can still achieve more than 90% cohesive failure effect on the surface of the ABS base material after being soaked in water for 7 days, and the adhesive has excellent water resistance and can be suitable for bonding the assembled toilet ground waterproof bottom box.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to an adhesive for an assembled bathroom floor waterproof bottom box and a preparation method thereof. Background technique [0002] With the development of modern industrial technology, house decoration can be manufactured in batches like machine production, as long as the prefabricated interior components are transported to the rough room for assembly. Prevalent, because the overall decoration speed of the prefabricated interior decoration is fast, and the production cost is low, it has also been rapidly promoted in China in recent years. The significant advantages of prefabricated interiors include the following aspects: 1) High quality stability, all prefabricated decoration materials are produced in the factory on the assembly line, and there is a systematic quality system control; 2) Environmental protection, due to the adoption of industrialized production, All the product...
