Abstract

The invention discloses a water-resistant epoxy resin used for a decoration sheet material. The water-resistant epoxy resin comprises the following components: 320-500 parts of a bisphenol type S epoxy resin base material, 52-83 parts of a DDSA curing agent, 18-32 parts of dimethyl formamide, 28-42 parts of a filling material, 19-27 parts of liquid polysulfide rubber, and 17-32 parts of dimethyl methylphosphonate. By reasonable control of ratio between the reactants, the reaction condition can be controlled in a reasonable mode, and the epoxy resin adhesive with high endurance used for a light industry and a weaving industry is prepared. The epoxy resin adhesive has the excellent moisture resistance and heat resistance, excellent machinery characteristics such as impact resistance, and has good bonding performance and endurance performance, and a preparation method is simple and easy to operate, and is suitable for industrial production.

Description

technical field [0001] The invention relates to the field of polymer gel, in particular to a water-resistant epoxy resin used for bonding decorative boards. Background technique [0002] House decoration adhesives are widely used in the fields of decorative plastics or wood material processing as a commonly used adhesive product in the light industry. For house decoration, adhesives are required when bonding multi-layer materials. However, the common adhesives commonly used at present usually contain organic poisons such as aldehydes, and their release will affect human health. Therefore, how to solve the pollution gas released by ordinary adhesives is a technical problem that needs to be solved urgently. [0003] And epoxy resin adhesive can solve the problem of existing building adhesive as a kind of environment-friendly gel material, and described epoxy resin adhesive is a class by epoxy resin base material, curing agent, diluent, accelerator and Engineering adhesives f...
