Abstract
The invention discloses an environment-friendly wood paint consisting of the following compositions in parts by weight: 75-80 parts of TPGDA modified waterborne polyurethane, 0.2-0.8 parts of a wetting agent, 0.01-0.05 parts of a defoaming agent, 2-5 parts of a film-forming additive, 0.1-0.5 parts of a dispersing agent, 1-5 parts of a cosolvent, 0.1-0.5 parts of a flatting agent, 0.05-0.3 parts of a preservative and 0.1-0.6 parts of a thickening agent. The compositions are evenly mixed so that the environment-friendly wood paint is obtained. In the invention, a little organic solvent is adopted in the TPGDA modified waterborne polyurethane emulsion, so that the usage amount of the film-forming additive is greatly reduced and the obtained floor nursing agent has good water resistance and strong environmental protection property.
Description
Technical field
The present invention relates to a kind of environment-friendly type wood lacquer, belong to chemical field.
Technical background
Traditional wood lacquer has good physical and mechanical properties, but film formation at low temp, levelling property and snappiness are poor, needs to add a large amount of film coalescence aid, can affect water tolerance, the resistance to bond of floor nursing agent, reduces it to the sticking power of ground.In addition, contain a large amount of solvents in the tradition wood lacquer, increased cost, environment friendly is poor, affected the range of application of wood lacquer, and aqueous polyurethane only contains a small amount of organic solvent take water as dispersion medium, be a kind of pollution-free, economize the energy, ep-type material, the wood lacquer feature of environmental protection for preparing take it as base-material is good.
The emulsion that this patent employing tri (propylene glycol) diacrylate (TPGDA) modified aqueous polyurethane obtains is as the main component of wood lacquer, the high-wearing feature of urethane and good mechanical property and vinylformic acid good weathering resistance and water tolerance are organically combined, learn from other's strong points to offset one's weaknesses, make aqueous polyurethane performance be improved significantly, more meet the requirement of preparation environment-friendly type wood lacquer.Simultaneously, the film forming properties of the emulsion that employing tri (propylene glycol) diacrylate (TPGDA) modified aqueous polyurethane obtains improves, therefore in the process of preparation environment-friendly type wood lacquer, can greatly reduce the consumption of film coalescence aid, reduce the impact of film coalescence aid on the floor nursing agent water tolerance.
Summary of the invention
The purpose of this invention is to provide a kind of wood lacquer with excellent film-forming properties, levelling property, snappiness, feature of environmental protection.
For realizing above purpose, the prescription of wood lacquer of the present invention is: in 100 parts of weight parts, and tri (propylene glycol) diacrylate (TPGDA) modified aqueous polyurethane emulsion 75-80 part, wetting agent 0.2-0.8 part, defoamer 0.01-0.05 part, film coalescence aid 2-5 part, dispersion agent 0.1-0.5 part, solubility promoter 1-5 part, flow agent 0.1-0.5 part, sanitas 0.05-0.3 part, thickening material 0.1-0.6 part, the water of surplus.
Wherein the preparation process of acrylic ester modified water-soluble polyurethane emulsion is: at first with 2,6 tolylene diisocyanates (TDI), polyoxyethylene glycol (PEG3000), BDO (BDO), dimethylol propionic acid (DMPA) prepare performed polymer for raw material.In reaction process, add N-Methyl pyrrolidone to reduce viscosity.Then after end-blocking and neutralization reaction, add tri (propylene glycol) diacrylate (TPGDA) and water and carry out emulsification, add an amount of initiator, obtain the emulsion of acrylate and aqueous polyurethane modification by copolymerization.
Wherein the proportioning of performed polymer is: the mol ratio of TDI and PEG3000, DMPA, BDO is 1.3:1-1.4:1, and BDO accounts for the 2%-3% of performed polymer quality, and DMPA accounts for the 5%-6% of performed polymer quality.
The preparation technology of wood lacquer of the present invention is: the water, wetting agent, defoamer, film coalescence aid, dispersion agent, solubility promoter, flow agent, sanitas, the thickening material that add successively proportioning in container, fully stir, add again the acrylic ester modified water-soluble polyurethane emulsion, after stirring, leave standstill, obtain wood lacquer after the filtration.
The beneficial effect that the present invention produces is, the emulsion that this patent employing tri (propylene glycol) diacrylate (TPGDA) modified aqueous polyurethane obtains is as the main component of wood lacquer, this emulsion itself has been gathered the high-wearing feature of aqueous polyurethane and good mechanical property and good weathering resistance and the water tolerance of vinylformic acid on the one hand, enlarged the range of application of wood lacquer, on the other hand because this emulsion has good film-forming properties, in the process of preparation floor nursing agent, can greatly reduce the consumption of film coalescence aid, reduced film coalescence aid to water tolerance, the impact of resistance to bond has reduced cost.In addition, because the organic solvent content that polyaminoester emulsion contains is few, so the wood lacquer feature of environmental protection that makes is good.
