Abstract
Alkali-resistanat coating without containing BPA is composed of, by weight, 50-70% of acrylic resin, 3-10% of saturated polyester resin, 5-10% of HMMM namely hexamethoxymethylmelamine resin, 5-10% of phenolic resin without containing BPA, 0.2-0.5% of PVB namely polyvinyl butyral, 1-3% of diacetone alcohol, 2-5% of DBE high-boiling-point solvents, 0-0.5% of flattening agents, 1-2% of adhesion promoters and 0-2% of diluents. According to the alkali-resistant coating without containing BPA, the saturated polyester resin is matched with the phenolic resin without containing BPA and acrylic resin, and therefore the coating, such as food, adhesion agents, hair dye, hair removal agents, chemicals, medicines, and toothpaste, which is good in alkali resistance, excellent in chemical corrosion resistance and good in acid resistance and is mainly used for inner surfaces of aluminum hose containers is prepared.
Description
Technical field
The present invention relates to technical field of coatings, especially relate to a kind of alkali resistance coating not containing BPA for aluminum flexible pipe internal surface.
Background technology
At present, there is BPA (dihydroxyphenyl propane) residue problem in the coating made due to epoxy resin, and BPA is one of time upper most popular industrial compound, mainly for the production of multiple macromolecular materials such as polycarbonate, epoxy resin, polyphenylene oxide resin, unsaturated polyesters.In the manufacturing processed of plastics, add BPA and can make it have the characteristic such as water white transparency, durable, light and handy and outstanding protecting against shock, especially acid vegetables and fruit can be prevented from internal corrosion metal vessel, be therefore widely used in the manufacturing processed of the packaging of tinned pre-and beverage, feeding bottle, water bottle, tooth filling seal gum used and other hundreds of daily necessities.But research shows that BPA is poisonous, and human body absorbs BPA powder for a long time and is harmful to liver function and renal function, especially severe be that it can reduce the content of protoheme in blood.
Put into effect the laws and regulations of much forbidding BPA both at home and abroad at present, as: European Union (EU) 10/2011 rules and regulations food contact material BPA content is no more than 0.6mg/kg; Denmark and Belgian rules and regulations forbid that less than 3 years old children's food contact material and article contain BPA; France's regulations forbid less than 3 years old children's food contact material and article, to forbid that all food contact materials and article contain BPA on January 1st, 2015, Nevada, USA is by forbidding BPA laws and regulations BillNO.354, rules and regulations: from 1 day January in 2014, anyone must not manufacture, sells or distribute bottle, the cup of any intentional interpolation BPA in Nevada, if this bottle or cup are designed to carrying liquid, food, have directly for the danger of less than 4 years old children; Separately rise on June 1st, 2014, anyone must not manufacture in Nevada, sells or distribute and anyly deliberately insert any infant food of splendid attire of BPA or the container of infant formula powder.Therefore, international and domestic food packaging industry is favored to have to the coating of BPA-free and is added.
Summary of the invention
For the problems referred to above that prior art exists, the applicant provides a kind of not containing alkali resistance coating and preparation method thereof of BPA.It is good that the present invention adopts saturated polyester resin to arrange in pairs or groups not make alkali resistance containing the resol of BPA and acrylic resin, chemicals-resistant corrosion is excellent, acid resistance is good, be mainly used in the internal surface coating of aluminum flexible pipe container, as food, tackiness agent, hair dye, trichogen, chemical, medicine and toothpaste etc.
Technical scheme of the present invention is as follows:
Not containing an alkali resistance coating of BPA, be made up of the component of following weight percents:
Described saturated polyester solid content is 100%wt, and hydroxy radical content is 10%, and acid number is less than 2mgKOH/g.
Described thinner is the acetone of mass ratio 1:1 and the mixing solutions of dimethylbenzene.
Not containing a preparation method for the alkali resistance coating of BPA, concrete steps are as follows:
(1) PVB and polyvinyl butyral acetal are placed in diacetone alcohol, stir, for subsequent use after impurity screening;
(2) above-mentioned DBE high boiling solvent, flow agent, adhesion promoter are placed in thinner and are pre-mixed evenly, for subsequent use after impurity screening;
(3) acrylic resin and saturated polyester resin are placed in container, use stirrer with 400-800rpm Rate Dispersion and add subsequent material successively to adhesion promoter with this stirring velocity, after using thinner to be adjusted to required viscosity after stirring with 800-1000rpm, continuing to be uniformly dispersed with 300-500rpm, after being filtered by uniform for dispersing and mixing mixture 240-360 mesh filter screen, gained is finished product.
The technique effect that the present invention is useful is:
The present invention abandons using the conventional epoxy resin of excellent properties still containing BPA that has to do raw material, but choice for use does not contain the acrylic resin of BPA as matrix resin, 100% saturated polyester resin admittedly contained of simultaneously arranging in pairs or groups thinks the snappiness that paint film provides enough, use multi-functional HMMM as linking agent, solidify the enough physical strengths of acquisition and snappiness under 240-260 DEG C of condition after 5-6 minute, the solids content of coating is high, and constructability operates; Heavy metal free raw material, not containing BPA; There is excellent acid resistance, alkali resistance, good chemical resistance and not containing BPA.Be applicable to the application of the internal surface coating of aluminum tubular substrate, the form of construction work construction that normal air can be adopted to spray.
