Abstract
The invention discloses UV photocuring primer. The primer is prepared from, by weight, 60-65% of bisphenol A type epoxy resin E-35, 10-15% of TPGDA, 8-12% of TMPTA, 1-2% of benzophenone, 10-15% of acetic ester, 4-6% of modified vital gluten, 0.5-0.8% of antifoaming agents and 0.5-1% of thickening agents. The UV photocuring primer is low in volatility, low in smell, low in environmental pollution, high in hardness, transparency, brightness and leveling property, high in curing speed and high in production efficiency; the primer is cured at the normal temperature and is applicable to a variety of substrates; energy is saved, and energy consumption accounts for 1/5 that of a traditional coating; performance indexes of all aspects such as coating transparency, acid and alkali resistance, salt spray resistance and resistance to organic solvent such as gasoline are high, a paint film of the primer is particularly plumpy, and gloss of the primer is particularly outstanding.
Description
Technical field
The present invention relates to a kind of coating, be specifically related to a kind of UV photocuring clear bottom coating.
Technical background
UV-light (UV) solidifies application and application techniques is the new surface treatment technologies that the eighties is risen.This kind of coating utilizes ultraviolet radiation to cause resin solidification, compared with existing thermosetting coating, have quick solidifying, energy-conservation, ambient cure, pollution less, the advantage such as coating performance is superior, be new generation of green Chemicals.Coating with traditional technology solidification is compared, and ultraviolet-curing paint demonstrates the better transparency, so ultraviolet curing transparent base paint has become one of focus of UVCC area research.It can, in field application such as material of construction, sports goods, telecommunications, optics, wrapping material, trolley parts, be the novel material had wide application prospects.But for a long time, the technology of this product and produce market are external company and monopolize, and its price can be in any more always, therefore research and develop domestic UV photocuring clear bottom coating too impatient to wait.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, the UV photocuring clear bottom coating of good, the easy construction of a kind of feature of environmental protection, quick solidifying is provided.
The technical solution used in the present invention is as follows:
A kind of UV photocuring clear bottom coating, is made up of the raw material of following weight percents:
Preferably, a kind of UV photocuring clear bottom coating, is made up of the raw material of following weight percents:
According to above-mentioned formula, the raw material of each component is put in reactor, high-speed stirring 20-30 minute, filters and packages.
Described modified wheat gluten is obtained by following methods: get 4-6 part gluten powder, adding 15-20 part mass concentration is the NaOH solution of 10%, at 50-60 DEG C of stirred in water bath 2-3h, gluten powder is dissolved completely, 4-5 part mass concentration is the hydrochloric acid of 15% again, at 70-75 DEG C of stirred in water bath 1-2h, concentrated, vacuum-drying, grind into powder.
Described defoamer is one or more in polydimethylsiloxane, polyoxyethylene polyoxy propyl alcohol amidogen ether, the fatty acid ester compounded thing of higher alcohols, polypropylene glycerol aether, silicone emulsion.
Described thickening material is one or more in methylhydroxypropylcellulose, polyoxyethylene, polyvinylpyrrolidone, Polyacrylate Emulsion, polyvinyl alcohol.
In the present invention's formula, modified wheat gluten is except having excellent cohesiveness, mobility and levelling property, also improve the consistency with coating emulsion, solve the serious cracking of gluten powder virgin rubber in coating use procedure, make coating have more excellent levelling property and appearance of film.
UV photocuring clear bottom coating of the present invention comparatively traditional coating has following advantage:
(1) low volatilization, low smell, environmental pollution is little;
(2) there is high rigidity, high transparent, high brightness, levelling property;
(3) curing speed is fast, and production efficiency is high;
(4) ambient cure, is applicable to multiple base material;
(5) save energy, energy consumption is about 1/5 of traditional coating;
(6) performance index of the organic solvent each side such as coating transparent, acid and alkali-resistance, salt spray resistance, resistance to gasoline are all very high, and particularly its paint film is plentiful, gloss is particularly outstanding
(7) coating equipment fault is low, because UV coating is with solidified by ultraviolet ray radiation, thus can not block and etching apparatus, and conveniently, equipment failure rate is low for coated tool and pipeline-cleaning;
(8) solidification equipment is simple, and easy-maintaining, add that associated outfit of equipment is less than traditional coating equipment occupation space, facility investment is low.
Embodiment
Below in conjunction with specific embodiment, the present invention is further illustrated.
Embodiment
A kind of UV photocuring clear bottom coating, is made up of the raw material of following weight percents:
According to above-mentioned formula, be put in reactor by the raw material of each component, high-speed stirring 30 minutes, filters and packages.
Wherein, described modified wheat gluten is obtained by following methods: get 5 parts of gluten powders, adding 18 parts of mass concentrations is the NaOH solution of 10%, at 55 DEG C of stirred in water bath 3h, gluten powder is dissolved completely, then 5 parts of mass concentrations are the hydrochloric acid of 15%, at 72 DEG C of stirred in water bath 2h, concentrated, vacuum-drying, grind into powder.
The performance test results of the UV photocuring clear bottom coating that the present invention prepares is in table 1.
