Abstract
The invention discloses a kind of elastic stoving varnish composition, said composition comprises following component composition by weight percentage: the saturated polyester resin 90 ~ 94% of masked isocyanate 6% ~ 10% softness have employed and add masked isocyanate resin inside the saturated polyester resin of softness, polyisocyanates close by the material containing reactive hydrogen atom of Diacetylmonoxime or other simple function group, therefore two portions can attach together and chemistry reflection not occur, and have fabulous package stability.In use, just can be cross-linked both when the temperature of baking vanish is at 120 ~ 170 degrees Celsius.
Description
Technical field
The present invention relates to a kind of elastic stoving varnish composition.
Background technology
Baking vanish used in the market, when constructing, needs proportioning solidifying agent, thinner according to a certain percentage, obtains dry coating through high bake.Above-mentioned baking vanish also has following problems in use: 1, baking vanish and solidifying agent, thinner proportioning complexity, need to use electronic scales and just can complete proportioning, and proportioning is wanted accurately just can get a desired effect, and requires great effort consuming time; 2, after baking vanish adds solidifying agent, pot life is short, easily solidifies, and brings inconvenience to client's construction; 3, paint needs baking time long, and efficiency is low, generally needs baking 60-80 DEG C of more than * 45-60min ability dry, greatly wastes the energy.
Summary of the invention
The object of this invention is to provide a kind of elastic stoving varnish composition, to solve the above-mentioned problems in the prior art.
In order to achieve the above object, the present invention is realized by following technical scheme.
A kind of elastic stoving varnish composition, said composition comprises following component composition:
Masked isocyanate
Soft saturated polyester resin
A kind of elastic stoving varnish composition, said composition comprises following component composition by weight percentage:
Masked isocyanate 6% ~ 10%
Soft saturated polyester resin 90 ~ 94%
Present invention employs and add masked isocyanate resin inside the saturated polyester resin of softness, polyisocyanates close by the material containing reactive hydrogen atom of Diacetylmonoxime or other simple function group, therefore two portions can attach together and chemistry reflection not occur, and have fabulous package stability.In use, just can be cross-linked both when the temperature of baking vanish is at 120 ~ 170 DEG C.
The invention solves traditional baking vanish and execute man-hour requirement and to complete by electronic scales a difficult problem for component proportioning, solve traditional baking vanish after component mixing by the restriction using the active phase, to be finished in 4 hours after tradition proportioning and not so can solidify, and the paint that elastic stoving varnish of the present invention has diluted cannotd be used up the same day, place after sealing and within second day, can continue to use, it just can be cross-linked both only when baking vanish.Elastic stoving varnish composition of the present invention also solves traditional baking vanish needs to be equipped with the difficult problem that base paint special could adhere to, and it can adapt to various hardware of having painted and the high-temperature resistance plastice of having painted, and does not limit by priming paint.Elastic stoving varnish composition of the present invention improves the time of drying of paint, shortens to 20-30 minute, improve production efficiency by original 40 minutes.
Embodiment
The present invention is further illustrated below by embodiment.
Embodiment 1
A kind of elastic stoving varnish composition provided by the invention, have employed to add masked isocyanate resin inside the saturated polyester resin of softness, masked isocyanate resin and soft saturated polyester resin are all known substances, can buy from the market, soft saturated polyester resin is commonly called as elastic stoving varnish.Elastic stoving varnish composition of the present invention by weight percentage said composition comprises following component composition:
Masked isocyanate 6% ~ 10%
Soft saturated polyester resin 90 ~ 94%
Embodiment 2
The present embodiment 2 by the saturated polyester resin of its softness by weight percentage said composition comprise following component composition:
Bayer 165240%, silicon-dioxide 6.5%, dibutyl tin laurate 0.3%, polyether modified siloxane flow agent 0.5%, toluene 11%, methyl iso-butyl ketone (MIBK) 10%, ethyl ester 14.7%, diacetone alcohol 10%
Masked isocyanate 7% is added in above-mentioned composition.
