Abstract
The coloured non-toxic nitrolacquer for toys is prepared from nitrocotton, glyptal resin, rosin modified malic resin, non-toxic pigment, phthalate, non-drying plant oil, acetate, and ketone in one step through dispersing, dissolving, stirring and filtering in a special dispersing container, and features simple process, very low contents of 8 harmful heavy metal elements such as Pb, Cr, Ba, etc. and less environmental pollution.
Description
The present invention relates to proportioning and " single stage method " manufacturing process thereof of the nitrocellulose non-toxic toy lacquer of all kinds of toy surface decoration and protection.
At present, the common nitro toy lacquer that China's toy industry generally uses, eight heavy metal species constituent contents such as lead, chromium, barium, selenium, arsenic, antimony, mercury, cadmium are very high in the paint film, well beyond the EN71 of European Community toy safety standard, and all adopt traditional technology manufacturing, technological process to be divided into slurry and mix, pigment grind disperses, the dissolving of nitro-cotton, multiple working procedures such as paint color matching exist complex process, facility investment is big, spillage of material is many, and is seriously polluted, the shortcoming that production cost is high.Countries in the world attach great importance to all that contents of heavy metal elements exceeds standard to the harm of human body in the toy coating, have worked out safety standards separately one after another: as the ASTMT963 of the U.S.; 5665 of Britain; The K5681 of Japan; The EN71 of the European Community; The GB6675 of China etc. clearly stipulate the upper limit (UL) of contents of heavy metal elements in the toy coating, and are wherein the tightest with European Community's EN71 standard-required.According to European Community various countries regulation, the toy of transporting to this area from now on must meet the EN71 of European Community toy safety standard.Toy lacquer is defective to be the biggest obstacle of the current toys export of China, for satisfying pressing for that toy industry squeezes into the international market, encourage R﹠D institution to work out the nontoxic toy lacquer that can meet the EN71 of European Community standard, China National Light Industrial Products Department has listed nitrocellulose non-toxic toy lacquer of all kinds in one nine nine two annual light industry science and technology expansion funds and has subsidized project.
The purpose of this invention is to provide and a kind ofly can meet the EN71 of European Community toy safety standard, the paint film of having again is plentiful, strong covering power, hard height, nitrocellulose non-toxic toy lacquer of all kinds and " single stage method " manufacturing process thereof of bright-colored characteristics such as pure.
Raw material of the present invention is: organic solvents such as nitro-cotton, benzene diformazan acid anhydride glycerine alkyd resin, maleficent acid resin, non-toxic pigment, phthalic ester and non-drying vegetables oil, acetic ester, ketone, alcohol.Technical recipe of the present invention ratio by weight percentage is: nitro-cotton is 10～18%; Benzene diformazan acid anhydride glyptal is 15～20%; The maleficent acid resin liquid is 10～20%; Non-toxic pigment is 1.5～10%; Phthalic ester and non-drying vegetables oil are 3～7%; Organic solvents 40～50% such as acetic ester, ketone, alcohol.Said single stage method manufacturing process: earlier nitro-cotton is dropped into special-purpose Scattered Kettle, adding is pure, toluene organic solvent is wetting, add non-toxic pigment, high speed dispersion 46～60 minutes adds ester, ketone organic solvent, be stirred to the nitro-cotton dissolving fully, add benzene diformazan acid anhydride glycerine alkyd resin then, maleficent acid resin liquid, phthalic ester and non-drying vegetables oil, stir, after filtration packing.The feature of this manufacturing process is: replace the basin of preparing burden in the traditional technology with a special-purpose Scattered Kettle, grout mixer, triple-roller mill, the nitro-cotton dissolving vessel, equipment such as paint mixing tank, slurry in the traditional technology is mixed, and pigment grind disperses, the dissolving of nitro-cotton, paint, multiple working procedures such as color matching concentrate in same the special-purpose Scattered Kettle " step " and finish.Not only reduce equipment, save facility investment, and simplify technology, improved product performance.
Adopt advantage of the present invention, effect as follows:
One, solved eight kinds of key issues that harmful contents of heavy metal elements exceeds standard such as lead, chromium, barium, selenium, arsenic, antimony, mercury, cadmium in the toy lacquer, made it well below state-of-the-art toy safety standard---the EN71 of European Community standard (seeing Table 1) in the world.Of the present invention succeeding in developing is for the toys export of China has from now on been cleared away biggest obstacle.For squeezing into the international market, made major contribution.(attached: Hong Kong commodity inspection company limited trial report).
Two, technology is simple, low equipment investment.The major equipment of whole process of production of the present invention is exactly a special-purpose Scattered Kettle, and comparable traditional technology is saved 60% facility investment, and has simplified production technique greatly.Quality product improves a class.
Three, can reduce production costs greatly.Whole process of production of the present invention is all carried out at air-tight state, and product returns the rate height, and is low in the pollution of the environment, power consumption is about 1/3rd of traditional technology, and the production efficiency height, and the color of nontoxic toy lacquer can be by user's requirement, by adding different non-toxic pigments, can obtain nitrocellulose non-toxic toy lacquer of all kinds.
Technical process of the present invention:
Nitro-cotton is wetting-→ colo(u)rant dispersion-→ the nitro-cotton dissolving-→ paint-→ filter-→ the finished product can.
Embodiment 1:
As make a kind of yellow nitrocellulose non-toxic toy lacquer.
At first the 140kg nitro-cotton is dropped into special-purpose Scattered Kettle, add 210kg alcohol, toluene organic solvent is wetting, yellow non-toxic pigment 75kg in the adding, high speed dispersion 60 minutes adds 230kg ester, ketone organic solvent, stirring until the nitro-cotton dissolving fully, add 160kg benzene diformazan acid anhydride glycerine alkyd resin then, 140kg maleficent acid resin liquid, 45kg phthalic ester and non-drying vegetables oil, stir, after filtration packing.
Embodiment 2:
And for example make a kind of green nitrocellulose non-toxic toy lacquer.
At first specially and Scattered Kettle with 128kg nitro-cotton input, add 220kg alcohol, toluene organic solvent is wetting, add medium green non-toxic pigment 70kg, high speed dispersion 50 minutes adds 210kg ester, ketone organic solvent, stirring until the nitro-cotton dissolving fully, add 170kg benzene diformazan acid anhydride glyptal then, 160kg maleficent acid resin liquid, 42kg phthalic ester and non-drying vegetables oil, stir, after filtration packing.
Claims (1)
