Example Embodiment
[0011] Example 1
[0012] A UV-water-based adhesive according to the present invention, the components of the adhesive and its weight ratio are: 30%-50% UV resin 85%, water 7.3%, defoamer 0.5%, increase Thickener 0.4%, wetting agent 0.3%, initiator 1.5%, solvent 5%.
[0013] Among the above components: UV-water-based resin uses CYTEC, BAYER or their mixture. The solvent is: ethers, alcohols or their mixtures. The defoaming agent is polysiloxane, silicon oxide polyether or their mixture, such as BYK025, BYK028 or their mixture produced by BYK. The thickener is ammonia, alcohol ammonia or their mixture, such as BYK425, Deqian DMEA or their mixture produced by BYK. The initiator is aromatic ketones, benzoin and its derivatives or their mixtures, such as BP, 184, 1173 or their mixtures produced by CIBA. The wetting agent can be nonionic organic surfactants or acrylics or their mixtures, such as TEGO WET series produced by TEGO.

Abstract
The invention discloses a UV-water-based adhesive. The adhesive comprises the following components based on a weight ratio: 60%-85% of UV-water-based resin with the concentration of 40%, 0.1%-0.5% of antifoaming agent, 0.3%-1% of thickening agent, 0.3%-1.0% of wetting agent, 1%-1.5% of initiator, 3%-5% of solvent and the balance of water, wherein, the UV-water-based resin with the concentration of 40% is polyurethane acrylic resins; the wetting agent consists of a nonionic organic surfactant, acrylic acid or a mixture of the nonionic organic surfactant and acrylic acid; and the solvent consists of ethers, alcohols or a mixture of ethers and alcohols. The UV-water-based adhesive has the advantages of simple production process and low production cost, and the formed paint film has the advantages of excellent adhesive force and good flexibility; and when the paint film is applied to the conventional wood floors and other wooden products, the adhesive force between a paint and a substrate can be greatly improved and the service life of the floors or wooden products can be prolonged.
Description
technical field [0001] The invention relates to a UV-water-based adhesive, in particular to a UV-water-based adhesive with strong flexibility and high adhesion. Background technique [0002] Since wood products such as wooden floors, wooden furniture, and wooden doors have wood grains, they are all porous surface structures, and oily UV light-curing coatings are directly coated on them, and it is difficult for the paint to penetrate into the substrate. The adhesion of the wood is not good, and the paint is easy to peel off, which affects the appearance and affects the service life of the floor and so on. Contents of the invention [0003] In order to solve the problem of adhesion between paint and substrate in wooden products such as wooden floors, wooden furniture, and wooden doors, the purpose of the present invention is to provide a UV-water-based adhesive, which has good film flexibility and has high Adhesion. [0004] The purpose of the present invention is achieved...
