Abstract
The invention relates to unsaturated polyester black backing varnish with high fillibility and a preparation method thereof. The black backing varnish is prepared from a main agent, a promoter, an initiator and a diluent according to a weight ratio of (90-110): (0.9-1.1): (1.1-1.3): (25-30), wherein the main agent is prepared from the following raw materials in parts by weight: 35-50 parts of unsaturated resin, 0.5-1 part of dispersant, 0.1-0.3 part of non-silicon flatting agent, 0.5-0.8 part of carbon black, 0.1-2 parts of zinc powder, 30-45 parts of talcum powder, 10-20 parts of styrene and 0.1-0.2 part of polymerization inhibitor; the promoter is cobalt naphthenate; the initiator is cyclohexanone peroxide; the diluent is styrene. The unsaturated polyester black backing varnish prepared by the preparation method disclosed by the invention not only has high fillibility and high hardness, but also is capable of improving the fullness of finishing coat, and no solvent is rest on the varnish films after the construction, so that the environmental tolerance of the construction is large.
Description
Technical field
The present invention relates to a kind of black backing varnish and preparation method thereof, particularly a kind of high fillibility unsaturated polyester black backing varnish and preparation method thereof.
Background technology
Existing PU painting is the problem of the complete rear dissolvent residual of ubiquity paint application not only, and fillibility is low, hardness is low, can not disposable film forming, construction environment is required high, and therefore reduced production efficiency, improved construction cost.
Summary of the invention
In order to solve the above-mentioned problems in the prior art, the invention provides a kind of high fillibility unsaturated polyester black backing varnish and preparation method thereof, the prepared unsaturated polyester black backing varnish of the present invention not only has high fillibility, high rigidity, can improve the finish paint fullness ratio, and paint film no solvent residue after construction, the construction environment tolerance is large.
Technical solution of the present invention consists of following two portions:
One) scheme one: a kind of high fillibility unsaturated polyester black backing varnish, and the weight proportion of being pressed 90-110:0.9-1.1:1.1-1.3:25-30 by host, promotor, initiator, thinner is formulated;
Wherein, host is formulated by following weight proportion by following raw material:
By Resorcinol and butyl ester, the weight proportion by 0.01-0.02:0.09-0.18 mixes stopper;
Promotor adopts cobalt naphthenate.
Initiator adopts cyclohexanone peroxide.
Thinner adopts vinylbenzene.
Wherein, host is main film forming substance, and thinner participates in the reaction film forming, and initiator and host are linked into active complex compound, and under promotor catalysis, complex compound reacts film forming with thinner.
In above-mentioned high fillibility unsaturated polyester black backing varnish,
The EFAK4010 dispersion agent that dispersion agent selects Dutch EFKA auxiliary agent company to produce.
Non-silicon flow agent is selected the fluorine-carbon modified polymkeric substance of EFAK.
The carbon black that the model that carbon black selects Mitsubishi chemical company to produce is MA100.
Zinc powder is selected coating level Zinic stearas TV-A.
Talcum powder is selected 800 order chemical grade talcum powder.
Vinylbenzene is selected common coating styrene monomer.
The chain macromolecule compound with ester bond and unsaturated double-bond that unsaturated polyester is formed by unsaturated dibasic acid dibasic alcohol or the unsaturated dibasic alcohol polycondensation of monounsaturated dicarboxylic acid.
The coventional type cobalt naphthenate product that promotor adopts Changfeng Chemical Plant, Shanghai to produce, be commonly called as Lan Shui.
The cyclohexanone peroxide product that initiator adopts Ao Bang auxiliary reagent factory, Guangzhou to produce, be commonly called as plain boiled water.
The above-mentioned weight proportion of the combination of these components and each component, by lot of experiments, determine, the coating that aforesaid combination and weight proportion make to form after the application of a kind of high fillibility unsaturated polyester black backing varnish of the present invention has the excellent balance of high fillibility, high rigidity and other technologies performance.
Scheme two) a kind of preparation method for the preparation of the described high fillibility unsaturated polyester black backing varnish of scheme one is characterized in that:
Prepared according to following preparation method by described host: after unsaturated polyester 35-50 part, dispersion agent 0.5-1 part and non-silicon flow agent 0.1-0.3 part are mixed, disperse 4-6 minute under 800-1000 rev/min of speed; Dispersion limit, limit adds carbon black 0.5-0.8 part, zinc powder 0.1-2 part and talcum powder 30-45 part, is dispersed to fineness and is less than 60 microns under 1200-1400 rev/min of speed; Continue to add vinylbenzene 10-20 part and stopper 0.1-0.2 part, then under 900-1000 rev/min of speed, disperse 4-6 minute to mixing.
Described host, promotor, initiator, thinner independent packaging respectively, allocate and get final product according to the described proportioning of scheme one before construction.
The invention has the advantages that, once brushing just can obtain thicker paint film, less demanding to painting environment, and the paint film decoration function is good.Because solvent benzol ethene can participate in reacting film forming fully, so paint film does not have dissolvent residual.In addition, solid content of the present invention is high, and during construction, viscosity is high, thereby can provide paint film high fillibility, solve the problem of PU product through the complete filling timber hole of repeatedly construction ability and conduit, unit surface is used the paint cost far below the PU product, has improved production efficiency simultaneously, and has had high rigidity after drying varniss, high fullness ratio, tough and hard wear resistant, be easy to maintenance, and can avoid the risk that adopts the PU black backing varnish later stage to subside.Formaldehyde of the present invention, benzene, VOC(volatile organic compounds) and free TDI (tolylene diisocyanate) quantity discharged low, health environment-friendly.
