Description
Technical field
The present invention relates to chemical powder paint fields, and in particular to a kind of water boiling resistance, resistance to for the spraying of vacuum cup surface
Soda acid, antibacterial and the powdery paints for being free of BPA.
Background technique
Terminal carboxyl polyester resin uses closing isocyanic acid using the solidification such as TGIC, T-105 and epoxy, hydroxyl telechelic polyester resin
Ester solidification.The polyester resin of two kinds of systems respectively has an advantage, after terminal carboxyl polyester resin and curing agent film-forming comprehensive performance compared with
For balance, price is lower, widely applicable；And hydroxyl telechelic polyester resin has splendid levelling after using cured with isocyanates
The outstanding properties such as property, solvent resistance and weatherability, but it is limited by the influence of the factors such as price, polyester tree currently used in the market
The main still terminal carboxyl polyester resin of rouge.However, as the improvement of people's living standards, requiring also to get over to the comprehensive performance of coating
Come higher, and individually terminal carboxyl polyester resin or hydroxyl telechelic polyester all more or less have partial properties defect.How to dash forward thus
Broken technical bottleneck, the polyester resin for developing excellent combination property are just particularly important.
Pure polyester powdery paints and are divided into polyester/TGIC (triglycidyl group isocyanuric acid according to the difference of curing system
Value) type and polyester/HAA (beta-hydroxy alkylamide) type, wherein polyester/TGIC type pure polyester powdery paints be applied to earliest it is weather-proof
Property field powdery paints, curing agent TGIC, it is a kind of isocyanuric acid ester three-glycidyl ester compounds, have it is following
Three features: (1) tool is there are three reactive active group, and when solidification can get higher crosslink density, due in structure
Rigid ring, the hardness of film after solidification are higher；(2) the molecular skeleton morning unsaturated double-bond after solidifying, therefore weatherability is very excellent
It is good；(3) nitrogen content is up to 14% in molecule, has certain self-extinguishment and anti-flammability.When solidification, by saturated carboxyl polyester
Epoxy group in carboxyl and TGIC crosslinks film forming, advantage it is clear that as good mechanical performance, chemical-resistant are good,
Yellowing is not likely to produce when high-temperature baking, outdoor weathe resistance is also very good, therefore 20th century were largely used.However, in recent years
The research discovery TGIC monomer come has virulent property to zooblast, can cause the heredity injury of animal, influence male insemination
And cause cytometaplasia and there is heredity, therefore its use is restricted in recent years, on the other hand, TGIC needs higher solid
Change temperature, therefore needs to consume more energy when coated solidified, the gradually attention with people to the problems such as environmentally friendly, energy saving,
The use of TGIC system is more increasingly restricted.By taking Europe as an example, Europe was once once weather-proof solid using TGIC as main body
Agent, it once occupied the market of entire European weather-resistant powder paint about 70%.But since mid-term European Community the 1990s
(existing European Union) is formally classified as toxic articles, and stipulated that any product using it must stamp danger signal since, now
It weather-resistant powder paint the market share less than 25%, in its also basic disappearance of Australia.
Beta-hydroxy alkylamide is a kind of novel carboxy resin curing agent, and toxicity in American-European application almost without presenting
The trend of liter, has the following characteristics that (1) curing rate is fast, can save the energy；(2) hardener dose is few, reduces material cost；(3)
There was only hydrone releasing when solidification, not can cause environmental pollution.There is excellent family with the cured film of beta-hydroxy alkylamide
Outer weather resistance, while the physical mechanical property of coating and chemical resistance are all than more prominent, it should say that the system is a kind of
Big promising New Curing System, with development potential.

Fruit and the quality not only health concerning the appearance property of product, more concerning user.It is different from the coating of other field, food
Industry proposes unprecedented challenge to powdery paints in safety.Various countries are even more relevant safe and healthy method of having worked out
Rule, product standard and detailed rules for the implementation, develop the food-grade coating to human health safety.There is " the People's Republic of China (PRC) in China
Food hygiene law ", GB 4805 " Food Can Lining epoxy-phenol resin paint sanitary standard ", " food containers cross chloroethene to GB 7105
Alkene inner-wall paint sanitary standard " etc. standards, develop food grade solvent type coating and water paint.U.S.'s food and drug surveilance
Management board (FDA) has formulated in relation to food and Package Ordinances.USA and EU executes FDA regulation, it is desirable that the family contacted with food
The migration of the surface covering of electrical appliance, food processing machinery, daily necessities etc. has to comply with the regulation of USFDA 21CFR 175.300
Technical indicator, use food-grade coating.And vacuum cup has its safety higher as the drinking-water articles in daily life
Requirement, also therefore powdery paints vacuum cup market application have big section blank, if this section of blank can be filled up, will bring through
Benefit of helping and technological revolution.
Due to using the particularity of object, the use of vacuum cup powdery paints has very harsh requirement, also facing

Coating on the inside of cup with sucking device, food and beverage (milk powder) tank.BPA is ubiquitous, from mineral water bottle, medical instrument to and food
The lining of packaging has its figure.Every year, 27,000,000 tons of plastics containing BPA of produced worldwide.But BPA can result in interior
Dyssecretosis threatens fetus and the health of children.Obesity caused by cancer and metabolic disturbance is recognized as related with this.
European Union thinks that feeding bottle containing bisphenol-A can induce sex premature, from March 2nd, 2011, forbids producing bisphenol-A containing chemical substance (BPA)
Baby bottles.Therefore the content for reducing bisphenol-A in product is the key that improve Product Safety.The material of this external cause vacuum cup
And characteristic is used, surface powder paint coatings easily cause poor poor adhesive force, temperature tolerance, water boiling resistance and wearability bad etc.
