Description
Technical field
The present invention relates to belong to Wooden furniture paint, be mainly used in wooden furniture and manufacture field, especially relate to a kind of high
PU light woodcare paint that hardness quickly can polish and preparation method thereof.
Background technology
At present, wooden furniture industry all can use this kind of PU gloss varnish, and this kind is the product of double-component, by leading
Paint and firming agent form, and main paint is usually the alkyd resin of synthctic fat acids, and firming agent is the trimer of TDI or TDI, product
Feature is that richness is good, and gloss is high, but typically compares slow curing, dress of could packing for 48 hours, if to polish, it is also desirable to 48 is little
More than time can be only achieved the hardness that can polish；As adjusted firming agent, strengthen the amount of trimer, can obtain the most dry fast, but meeting
Sacrifice the performance that richness is good and gloss is high.Therefore in terms of the dryness in existing PU gloss varnish technology of preparing and hardness,
Never obtain a good balance.
Summary of the invention
The present invention provides PU light woodcare paint that a kind of high rigidity quickly can polish and preparation method thereof.
In this programme, the raising degree of hardness is far beyond the requirement that can polish, and richness, glossiness are high, namely
Say while remain light product height richness and gloss, the performance of hardness can be greatly improved, breach existing product
The bottleneck of product；The relatively common light of the hardness of the next day clear product hardness of four or five days after construction, after the most direct effect is construction,
Paint film second day (16 hours) can be packed and be filled or polishing, breaches the bottleneck just can packed and polish conventional 48 hours,
Play a significant role improving wooden furniture manufacturing enterprise production efficiency, decrease stock.
The technical solution adopted for the present invention to solve the technical problems is:
The PU light woodcare paint that high rigidity quickly can polish, is characterized in that, including component A, B component, dilution component, A group
Part, B component, dilution component press the percentage by weight mixing of 1:1:0.8, wherein；
Described component A includes the raw material of following percentage by weight: 55% oil-free polyester resin I, 16% oil-free polyester resin II,
0.3% siloxane polymer, 0.5% acrylate polymer, 10% dimethylbenzene, 17.7% butyl ester；
Described B component includes the raw material of following percentage by weight: 66%TDI addition product, 33.5% butyl ester, 0.5% methyl ethyl ketoxime
Described dilution component includes the raw material of following percentage by weight: 60% dimethylbenzene and 40% butyl ester；
The chemical formula of described oil-free polyester resin I is:
HO(CH2)nC(CH3)2CH2COOC6H10COOCH2CC2H5CH2OHCH2COOC6H10COO(CH2)nOH
The chemical formula of described oil-free polyester resin II is:
HO(CH2)nC(CH3)2CH2COOC6H4COOCH2CC2H5CH2OHCH2COOC6H4COO(CH2)nOH
The chemical formula of described TDI addition product is:
C2H5C(CH2COONHC6H3(NCO)CH3)2CH2OCONHC6H3(NCO)CH3。
As another object of the present invention；
The preparation method of the PU light woodcare paint that high rigidity quickly can polish, comprises the steps:
(1) component A is prepared
Weigh each component according to the percentage by weight of claim 1, in the dispersion cylinder of general carbon steel material, first put into nothing
Oil polyester resin I and oil-free polyester resin II mix, then put into dimethylbenzene and butyl ester, stir 10min extremely with the speed of 600rpm
Uniformly, then dispersion limit in limit puts into siloxane polymer and acrylic polymer, and after finishing, speed with 1000rpm is divided again
Dissipate 15min, obtain component A；
(2) B component is prepared
Weigh each component according to the percentage by weight of claim 1, use the closed type of general carbon steel material band osculum to divide
Dissipate cylinder, first throw TDI addition product, then throw butyl ester and methyl ethyl ketoxime, with the Rate Dispersion 5min of 500rpm after finishing, obtain B component；
(3) mixing
The percentage by weight that preparation component A, B component, dilution component press 1:1:0.8 mixes, with pallette knife hand operated mixing 1
Minute uniformly prepare described PU light woodcare paint.
The invention has the beneficial effects as follows:
(1) the PU light woodcare paint that the high rigidity of the present invention quickly can polish, the PU light woodcare paint of contrast prior art,
Maximum improvement have employed this novel resin, current technology exactly, and PU light woodcare paint is all to use synthetic fatty acid
Alkyd resin realize, general is all uses the synthetic fatty acid of C8 and C9, and C8 is the most general, but richness is not
Enough, C9 richness is permissible, but dryness is very slow, difference of hardness, thus always total in terms of dryness hardness and between richness on market
It is to can not find a good equilibrium point；And technical scheme breaks through conventional thought, do not use the synthctic fat of routine
Acid, and have employed oil-free polyester resin (including oil-free polyester resin I and oil-free polyester resin II), due to oil-free polyester resin I
With the chemical constitution of oil-free polyester resin II linearly, not having unnecessary oils side chain, therefore resin has possessed the property that hardness is high
Energy；He is in the raw materials such as the alcohols synthesized select simultaneously, and the kind that have employed light (refers to that oil-free polyester resin I and oil-free are gathered
Ester resin II), therefore this resin can keep the performance of Gao Guang, supporting TDI addition product firming agent, is also to maintain the important of high glaze
Means.
(2) the PU light woodcare paint that the high rigidity of the present invention quickly can polish, the richness that accomplished, it is preferably selected pure
TDI addition product, if having arranged in pairs or groups trimer, it is likely that the defect that richness declines occur, in prior art, manufacturer is
It is to think the stiffening effect in order to reach, trimer curing agent will be added, but this scheme of the present invention has also broken this
Plant Traditional Thinking；By using this polyester resin, then TDI addition product firming agent of arranging in pairs or groups, good light mirror effect can be obtained.
