Description
Technical field
The present invention relates to powder surface coating material, particularly relate to a kind of thermosetting powder coating(s) of low-temperature curing.
Background technology
Production three stages of historical developments of the natural use of filmogen coating of the development experience of coating, the formation of coatings industry and synthetic resin coating.Production three stages of historical developments of the natural use of filmogen coating of the development experience of coating, the formation of coatings industry and synthetic resin coating.
First developmental stage of coating is the use of natural filmogen coating.China is the country using natural filmogen coating-lacquer in the world.Lacquer is exactly the raw lacquer often said, is the paint liquid extracting it on a kind of lacquer tree, preserves use with oilpaper sealing.First developmental stage of coating is the use of natural filmogen coating.China is the country using natural filmogen coating-lacquer in the world.Lacquer is exactly the raw lacquer often said, is the paint liquid extracting it on a kind of lacquer tree, preserves use with oilpaper sealing.
Lacquer belongs to lacquer, but have a lot of people to touch lacquer can be allergic, the taste that even somebody smells lacquer also can play measles.And lacquer is also very high to brushing technical requirements, so use lacquer uncommon in construction now.Lacquer belongs to lacquer, but have a lot of people to touch lacquer can be allergic, the taste that even somebody smells lacquer also can play measles.And lacquer is also very high to brushing technical requirements, so use lacquer uncommon in construction now.
Second stage is the formation stages of coatings industry.This in period oleum lini, a large amount of production of stand oil and application, impel the Cultivar development of varnish and colored paint rapid.The colored paint of coatings industry initial production is generally called in siccative oil by pigment.To, through allocating and being diluted to proper viscosity, use very inconvenient during construction.Afterwards, the coating of applicable construction requirement was directly prepared by coating material production factory, i.e. ready-mixed paint.Second stage is the formation stages of coatings industry.This in period oleum lini, a large amount of production of stand oil and application, impel the Cultivar development of varnish and colored paint rapid.The colored paint of coatings industry initial production is generally called in siccative oil by pigment.To, through allocating and being diluted to proper viscosity, use very inconvenient during construction.Afterwards, the coating of applicable construction requirement was directly prepared by coating material production factory, i.e. ready-mixed paint.
Before the nineties, most paint is all ready-mixed paint, and shortcoming is irritant smell, and dry slow; Advantage is good weatherability, and construction easily.The pollution of ready-mixed paint mainly owing to using solvent, and contains volatile organic matter (VOC), toluene, dimethylbenzene, the pollutents such as heavy metal in solvent.Before the nineties, most paint is all ready-mixed paint, and shortcoming is irritant smell, and dry slow; Advantage is good weatherability, and construction easily.The pollution of ready-mixed paint mainly owing to using solvent, and contains volatile organic matter (VOC), toluene, dimethylbenzene, the pollutents such as heavy metal in solvent.
Afterwards, create powder coating gradually, powder coating is little owing to polluting, therefore obtain the extensive favor of people, but existing powder coating can only be coated on conductor mostly, non-conductive material is then difficult to adapt to, what is more important, existing powder coating cost is high, is difficult to meet market demand.
Simultaneously, the condition of cure of existing thermosetting powder coating(s) accustomed to using is 200 DEG C × 10min or 180 DEG C × 20min, it requires that the curing oven in-furnace temperature of spraying equipment must reach more than 200 DEG C, thus allow the workpiece of spraying entered in stove progressively be warming up to 200 DEG C (or 180 DEG C), and this temperature is kept 10min(or 20min), to guarantee that workpiece surface is completed its program curing by dusty spray.
At protection environment for human survival, advocating the society of energy-saving and emission-reduction energetically, reduce curing oven temperature, save energy, reduce enterprise's production cost, is that the universal value that all enterprises are pursued is seen.We are necessary that developing a kind of solidification furnace temperature of working as only needs to reach 130 DEG C, can realize the powder coating of paint solidification for this reason.
Summary of the invention
In order to solve the problems of the prior art, the object of this invention is to provide that a kind of use range is wide, the temperature of thermofixation is low, energy-conserving and environment-protective, production cost be low, the low temperature heating-curing powder coating of market competitiveness of enterprises can be strengthened.
For achieving the above object, the present invention by the following technical solutions: a kind of thermosetting powder coating(s) of low-temperature curing, the content of its each component contained is respectively by weight:
Epoxy resin 30-40 weight part
Vibrin 30-40 weight part
Flow agent 1-3 weight part
Barium sulfate 20-30 weight part
Promotor 1-3 weight part
Catalyst aid 1-3 weight part
St-yrax 0.5-1 weight part.
Further, described flow agent is flow agent 388.
Preferred version, described vibrin is vibrin P-0583.
Further preferred version, described epoxy resin is epoxy resin E-12.
The content of each component that the thermosetting powder coating(s) of described low-temperature curing contains is respectively by weight:
Epoxy resin E-1235 weight part
Vibrin P-058335 weight part
Flow agent 3881 weight part
Barium sulfate 25 weight part
Promotor 2 weight part
Catalyst aid 1.5 weight part
St-yrax 0.5 weight part.
Promotor in low temperature thermosetting powder coating(s) of the present invention and catalyst aid interact, the epoxy resin and the vibrin that make originally could mutually must to carry out 180 DEG C time chemical reaction can also can react at a lower temperature, solve the low-temperature curing problem of thermosetting powder coating(s).The solidification value of powder coating of the present invention reduces 70 DEG C ~ 50 DEG C than the solidification value of existing powder coating, for energy-saving and emission-reduction and expansion product use range start Liao Yitiaoxin road.
Its detailed beneficial effect is as follows:
1, energy efficient:
The average indoor temperature of the whole year calculates with 20 DEG C by roughly, so, the heat (calorie) taken away by spraying workpiece should be workpiece " quality × specific heat × temperature rise ".Roughly " temperature rise " is exactly the difference of furnace temperature and room temperature.As can be seen here, whether energy-conservation, just see the ratio of " temperature rise ", the solidification value of powder coating of the present invention is 130 DEG C × 20min, its " temperature rise " is 130 DEG C-20 DEG C=110 DEG C, the solidification value of existing powder is 180 DEG C × 20min, and its " temperature rise " is 180 DEG C-20 DEG C=160 DEG C, and the ratio of its " temperature rise " should be 110 DEG C of ÷ 160 DEG C=0.6875.That is the energy-saving effect of this powder coating is about 32%, energy-conservation is exactly reduce production cost, and this is one of target of all enterprises pursuit.
2, can be lowered 50 DEG C to the curing oven furnace temperature that this powder coating carries out thermofixation, it is again to bringing a series of following beneficial effect;
<1> is because equipment use temperature is lowered to about 130 DEG C, so facility investment expense also can suitably reduce.The possibility that <2> equipment damages because being heated diminishes, and reduces the repair expense of equipment and repairs blowing out loss.The heat lost by radiation of <3> equipment greatly reduces, and improves the thermo-efficiency of equipment.The heat that the workpiece that <4> stove scatters and disappears is taken out of has completely diminished, and the room temperature in workshop can reduce greatly, improves the Working environment (especially in the day of high temperature and heating summer) of workman.<5> has expanded the scope of powder surface application: the product of the basic materials such as plastics, timber, fiber board all can adopt, and this patent powder carries out external coating to it.
