Abstract

The invention discloses a waterborne dip-coat cementing material. The waterborne dip-coat cementing material is characterized by being composed of a waterborne polyurethane dispersion, an acrylic emulsion, a film-forming auxiliary agent, ethyl alcohol and water. The waterborne dip-coat cementing material comprises the following components by weight: 40 to 50 parts of the waterborne polyurethane dispersion, 10 to 15 parts of an acrylate emulsion, 15 to 25 parts of the water, 0.3 to 0.7 part of fumed silica, 0.2 to 0.5 part of a multifunctional amine auxiliary agent, 0.5 to 1 part of a dispersant, 0.1 to 0.3 part of an anti-foaming agent, 10 to 20 parts of the ethyl alcohol, 5 to 10 parts of the film-forming auxiliary agent, 0.2 to 0.5 part of a bactericide and 0.2 to 0.5 part of a thickening agent. The waterborne dip-coat cementing material provided by the invention well solves the problems of strong odor, large VOV emission, short service time, poor adhesion force, easy cracking and the like for an oily seal primer, can well treat the problems of rib-stretching prevention, cementing property, defoaming property, grindability, precipitation and the like, has extremely low VOC emission and low odor, and simultaneously meets the requirements for performances and environmental protection.

Description

technical field [0001] The invention belongs to the field of water-based materials, and in particular relates to a water-based dipping cement material and a preparation method thereof. Background technique [0002] With the continuous advancement of science and technology, people pay more and more attention to environmental protection, and furniture coating is gradually transitioning from traditional oil-based coating to water-based coating, that is, "oil to water". [0003] The original "oil-based" dip-coating materials have serious problems such as strong odor, large VOV emission, short service life, poor adhesion, and easy cracking; in this field, it is urgent to develop a water-based dip-coating adhesive material to solve the above problems, so as to broaden the construction Tolerance, to achieve the purpose of reducing environmental pollution. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the invention provides a water-based dip-coat...
