Abstract
The invention relates to polyurethane matte white finish coat for non-benzene and odor-free furniture, which consists of a main agent, a curing agent and a diluent, wherein the main agent comprises hydroxyl acrylic resin, titanium white, solvent, a defoaming agent, a flatting agent, an anti-settling agent, a dispersing agent and a flatting agent; the curing agent comprises a toluene diisocynate tripolymer, toluene diisocynate-trimethylolpropane addition product and butyl acetate; and the diluent comprises the butyl acetate, cyclohexanone and propylene glycol monomethyl acetate. By adopting the technical scheme, the polyurethane matte white finish coat has the advantages that: an obtained paint film has less residual solvent and is tasteless after 12 hours; a formula does not contain chemical substances harmful to body health of human beings, such as benzene, methylbenzene, dimethylbenzene, other aromatic solvents and derivatives, methanol, glycol ether ester solvents, halogenated hydrocarbon and the like, and the excellent decorative and protective effects of the conventional polyurethane (PU) dual-component furniture paint are reserved in the formula; and the polyurethane matte white finish coat is easy to construct and is applicable to various construction modes such as spraying, electrostatic spraying and brush coating.
Description
Technical field
The present invention relates to a kind of polyurethane matte white finish paint, particularly a kind of without the benzene furniture polyurethane matte white finish paint of only distinguishing the flavor of.
Background technology
Current, along with the raising of people's material and cultural life, family product no longer is confined to general taste and decorative effect, and more pays close attention to the aspects such as health, comfortable, environmental protection.And wood furniture alcohol acid and polyurethane white finish paint on market though good decorative effect is arranged, contains the material of harmful HUMAN HEALTH such as benzene class, and solvent and a small amount of free TDI residence time long, not volatile, smell is difficult to eliminate.So exploitation without benzene, clean flavor, low-free TDI, particularly necessary to the harmless furniture lacquer product innovation of HUMAN HEALTH, has also become the focus of attention and the developing direction in market.Yet, the clean flavor product of many producers release now mostly adopts modes such as adding essence, mask agent, can only cover the irritating smell of benzene kind solvent in paint film and can not tackle the problem at its root, and essence, mask agent itself have very large smell, can not satisfy client's demand." the polyurethane matte white finish paint that a kind of woodenware is used; its invention is the dumb light white finish paint that proposes a kind of quick-dry type, anti-xanthochromia; do not mention " only distinguishing the flavor of without benzene " problem, so the present invention has certain difference with foregoing invention aspect function as disclosed in CN1557894A.
Summary of the invention
The objective of the invention is to solve the existing the problems referred to above of alcohol acid and polyurethane white finish paint of the prior art, provide a kind of without the benzene furniture polyurethane matte white finish paint of only distinguishing the flavor of, the defects that exists to overcome prior art.The present invention relates to it is characterized in that without the benzene furniture polyurethane matte white finish paint of only distinguishing the flavor of, formed by host, solidifying agent and benzene-free thinner;
Described host comprises the component of following weight percent:
Hydroxylated acrylic resin 45%～60%,
Titanium dioxide 20%～30%,
Viscosity adjustment thinner 16%～25%,
Defoamer 0.1%～0.3%,
Flow agent 0.1%～0.2%,
Anti-settling agent 0.1%～0.5%,
Dispersion agent 0.5%～1%,
Matting agent 3.2%～8%,
The per-cent sum of above each component is 100%;
Described curing agent component proportioning is:
Tolylene diisocyanate (TDI) tripolymer 40%～50%,
Tolylene diisocyanate (TDI)-TriMethylolPropane(TMP) affixture 20%～30%,
N-BUTYL ACETATE 20%～30%,
The weight percent component proportion of described benzene-free thinner is:
N-BUTYL ACETATE 60%～70%,
Pimelinketone 15%～20%,
1-Methoxy-2-propyl acetate 15%～25%.
It is characterized in that, described viscosity adjustment thinner is a kind of or its mixture in N-BUTYL ACETATE, pimelinketone or 1-Methoxy-2-propyl acetate, described defoamer is a kind of or its mixture in broken bubble polymkeric substance or polysiloxane solution, flow agent is polyether siloxane copolymer, described anti-settling agent is polyamide wax, described dispersion agent is the urethane that contains acid base material, and described matting agent is silicon-dioxide.It is characterized in that, the parts by weight proportioning of host and solidifying agent and thinner is: host: solidifying agent: thinner=100: 30～50: 50～80.Preparation method of the present invention is foolproof, and described host, solidifying agent and thinner are mixed respectively according to separately ratio, obtains above-mentioned host, solidifying agent and thinner, during use, mix according to aforementioned proportion, can construct, constructional method is the method for this area routine.The present invention sets about from formula, set about from the source of paint formulation, be conceived to people for the requirement of household without the clean flavor of benzene, take not add the materials that are harmful to health such as benzene class, the acrylic resin that the present invention adopts has the solvent release that obviously is better than traditional alkyd resins, and dissolvent residual is few, and has very good mechanical properties and the transparency of protecting light tint retention and Geng Jia, adopt the solidifying agent of low-free TDI and HDI, low-free TDI and HDI are residual few.This invention is difficult for delustring, the problem of color stuffing free settling by the characteristic of resin and the general acrylic resin of good collocation solution of auxiliary agent.
The beneficial effect that the present invention adopts above-mentioned technical solution to reach is: the matrix resin that 1, adopts is an easy delustring, extremely excellent solvent release acrylic resin, the paint film of gained after 12 hours residual solvent few, tasteless; 2, do not contain benzene,toluene,xylene and other aromatic solvents, aromatic derivant in the formula, the chemical substance of harmful HUMAN HEALTH such as methyl alcohol, glycol ether ester kind solvent and halohydrocarbon, the volatile substances such as selected solvent are all to reduce to greatest extent the human injury as principle; 3 formulas have kept good decoration and the protection effect of the two component furniture devices of conventional P U, and are easy to construction, the multiple forms of construction work such as applicable spraying, electrostatic spraying, brushing.
