Description
Technical field
The invention belongs to paint field, be specifically related to a kind of water-based mono-component extinction type clear finish and preparation method thereof.
Background technology
Present various coating types on the market are various, mainly are divided into organic coating and inorganic paint, and organic coating is divided into organic solvent type coating and organic water-borne coatings again according to the solvent difference of using.Organic solvent type coating is because VOC is high, can not satisfy people day by day enhanced to environmental protection requirement.
Organic water-borne coatings, i.e. water-borne coatings becomes the focus of research now day by day.Conventional water-miscible paint is poor to the timber wettability, and also usually bad with other water-baseds embodiment consistencies, emulsion is destroyed under high-speed stirring easily.
Summary of the invention
The technical problem that the present invention will solve is that water-miscible paint is poor to the timber wettability in the prior art, and also usually bad with other water-baseds embodiment consistencies, emulsion is destroyed under high-speed stirring easily.
The technical scheme that the present invention solves this technical problem is: water-based mono-component extinction type clear finish, and its prescription is: by weight, 40～50 parts of aqueous pu dispersions; 20～30 parts of polyacrylic acid modified urethane, 0.1～0.5 part of wetting agent, 1.0～2.0 parts of thickening materials; 0.1～0.5 part of skimmer, 2.0～8.0 parts of matting agents, 0.1～0.5 part of flow agent; 0.1～2.0 part of film coalescence aid, 1.0～5.0 parts in water.
Preferably, in the above-mentioned said prescription, 45 parts of aqueous pu dispersions, 25 parts of polyacrylic acid modified urethane, 0.3 part of wetting agent, 1.5 parts of thickening materials, 0.3 part of skimmer, 5 parts of matting agents, 0.3 part of flow agent, 1 part of film coalescence aid, 3 parts in water.
The present invention also provides a kind of preparation method of water-based mono-component extinction type clear finish; By weight; Low whipping speed is to add 40 ~ 50 parts of aqueous pu dispersions, 20 ~ 30 parts of polyacrylic acid modified urethane, 0.1 ~ 0.5 part of wetting agent, 1.0 ~ 2.0 parts of thickening materials, 0.1 ~ 0.5 part of skimmer successively to container under 600～800r/min condition, and the back that stirs slowly adds 2.0 ~ 8.0 parts of matting agents, and mixing speed is transferred to 1200～1500r/min; Be dispersed to fineness≤30um; Add 0.1 ~ 0.5 part of flow agent, 0.1 ~ 2.0 part of film coalescence aid then successively, again mixing speed is transferred to 600～800r/min, stir; 1.0 ~ 5.0 parts of cleaning equipments of water arrive 120KU～130KU with adjustment viscosity, filter and obtain finished product.
During use, the proportioning allotment of pressing this Chan Pin ︰ water=1 ︰ 0.3～0.5 is even, leaves standstill after bubble is eliminated, can construct in 10 minutes.
The present invention is to be the coating of solvent or dispersion medium with water, and it has important environment protection significance, asepsis environment-protecting, and hazardous solvent such as containing benezene does not contain free TDI.
The present invention adopts polyacrylic acid modified urethane, aqueous pu dispersions, ACRYLIC EMULSION process self chemically crosslinked to send out and answer, and generates a kind of high performance high molecular polymer.Solved the problem of conventional water-miscible paint to timber wettability difference, and the phenomenon bad with other water-based system consistencies; Solved the possibility of emulsion meeting breakdown of emulsion under high-speed stirring.
The present invention has excellent gloss and outward appearance, and stain resistance and chemical moral character are excellent, excellent mechanical property, can with other paint construction simultaneously such as rubber-emulsion paint, processing ease and variation.
