Description
Technical Field
The invention belongs to the technical field of coatings, and particularly relates to a low-VOC high-fullness environment-friendly PU (polyurethane) bright clear finish.
Background
The paint is a continuous solid film which is coated on the surface of an object to be protected or decorated and can form firm adhesion with the object to be coated, also called paint film or coating, and is a viscous liquid which is usually prepared by taking resin or oil or emulsion as a main material, selectively adding pigment, filler and corresponding auxiliary agents and using organic solvent or water. The coatings can be classified into different categories according to different classification methods, wherein the coatings can be classified into: solvent-based coatings, water-based coatings, powder-based coatings, high-solids coatings, metallic coatings, pearlescent coatings, and solventless coatings; the coating can be classified into a matt coating, a flat coating, a matte coating and a high gloss coating (also called a bright coating) according to the brightness of the appearance of the coating film.
Nowadays, the requirement for environmental protection is getting higher, and the requirement for environmental protection is becoming more and more trend to realize low VOC of oil paint. Meanwhile, for the full-bright furniture products, the Chinese people still love the products with high fullness.
The existing oil paint still has various problems during construction under low VOC and high solid content, such as construction viscosity problem, construction compatibility, balance of leveling property and defoaming property after construction, and the like. One of the obvious differences in GB18581-2020 over GB18581-2009 is also the reduction in the use of triphenyl.
Therefore, how to provide a coating which has good workability under the conditions of high fullness and low VOC and does not contain benzene solvents is a technical problem to be solved at present.
Disclosure of Invention
The invention aims to provide a low-VOC high-fullness environment-friendly PU (polyurethane) bright clear finish. Especially, the effects of high fullness and good construction performance are realized under the conditions of no benzene solvent and low VOC.
The technical scheme adopted by the invention for solving the problems is as follows:
the low-VOC high-fullness environment-friendly PU (polyurethane) bright clear finish is characterized by comprising a component A and a component B;
the component A comprises the following components in parts by weight: 75-90 parts of high-solid content synthetic fatty acid resin, 5-18 parts of cyclohexanone, 4-6 parts of butyl ester, 0.1-0.9 part of flatting agent and 0.5-1 part of defoaming agent;
the component B comprises the following components in parts by weight: 25-40 parts of butyl ester, 50-56 parts of toluene diisocyanate and 10-20 parts of hexamethylene diisocyanate based polyisocyanate.
Further, the solid content of the high-solid content synthetic fatty acid resin is 85-99%, and the viscosity is lower than 18000MPa s/25 ℃. Compared with the conventional resin, the high-solid-content synthetic fatty acid resin and the hexamethylene diisocyanate based polyisocyanate have high solid content but low viscosity, can reduce the addition of organic solvent during construction, reduce the discharge amount of VOC (volatile organic compounds), realize high-solid-content construction, and finally achieve the effect of high fullness, wherein the film thickness of a paint film can reach more than 40 mu m.
Preferably, the toluene diisocyanate is at least one of a toluene diisocyanate trimer and a toluene diisocyanate adduct. Toluene diisocyanate with a solids content of more than 50% is preferred.
Further, the mass ratio of the component A to the component B is 1 (0.9-1.1), and the component A and the component B are mixed according to the mass ratio during construction.
Further, the defoaming agent is a polysiloxane defoaming agent. The polysiloxane antifoaming agent has strong foam breaking capability, and can well solve the foaming problem during high-viscosity spraying. Thereby generating the paint film effect of no prickly heat and dark bubbles.
Further, the leveling agent is at least one of an acrylate leveling agent, a fluorine modified acrylate leveling agent and a polyether modified organic silicon leveling agent.
Preferably, the leveling agent is 0.1-0.5 part of acrylate leveling agent, 0.1-0.3 part of fluorine modified acrylate leveling agent and 0.05-0.1 part of polyether modified organic silicon leveling agent.
Further, the mass ratio of the component A to the component B is 1 (0.9-1.1). When in construction, the components are mixed and used according to a proportion, other organic solvents are not needed to be used as diluents, and the construction solid content can reach more than 58 percent.
The invention has the beneficial effects that:
the invention provides a low-VOC high-fullness environment-friendly PU (polyurethane) bright clear finish, which is characterized in that the selected high-solid-content low-viscosity synthetic fatty acid resin and hexamethylene diisocyanate based polyisocyanate can reduce the use of organic solvents and reduce the discharge amount of VOC, the high-solid-content low-viscosity synthetic fatty acid resin has high hydroxyl content, the hexamethylene diisocyanate based polyisocyanate has high isocyanate group content, the cross-linking density of the two is high after the two react, and the chemical resistance is improved. Three leveling agents are used in a matched manner, so that the flatness of the surface of the whole paint film is improved.
The invention also uses cyclohexanone and butyl ester as solvents, reduces the addition of triphenyl, and is more environment-friendly.
The invention also uses the acrylate flatting agent, the fluorine modified acrylate flatting agent and the polyether modified organic silicon flatting agent in a matching way, and can solve the problem of the flatting property of high-viscosity spraying. The polyether modified organic silicon leveling agent can lower the surface tension strongly, realize rapid short wave leveling, float to the surface and improve the hand feeling and scratch resistance; the acrylate leveling agent and the fluorine modified acrylate leveling agent are long-wave leveling agents, and the late-stage slow leveling effect of the coating can be realized. In the PU gloss clear finish paint provided by the invention, the dryness is slower than that of the conventional PU gloss clear finish paint, and enough time is provided for the acrylate flatting agent and the fluorine modified acrylate flatting agent to play a role, so that the flat paint film effect of the product is achieved.
The polysiloxane antifoaming agent used in the invention has strong foam breaking capability, and can well solve the foaming problem in high-viscosity spraying. Thereby generating the paint film effect of no prickly heat and dark bubbles.
