Abstract
The de luxe polyurethane enamel paint contains two components: A and B. A contains polyester resin, alkyd resin, polyester ether and acrylic resin containing hydroxyl and B contains toluenediisocyanate, trimethanol propane adduct and biuret. When A is mixed with B, crosslinking reaction of isocyanato group on hydroxyl group occurs to form a film that contains great deal of amino acid ester bonds, double ester bonds, unsaturated oil ester double bonds, biuret bonds and allophanate bonds. It features good insulation and weatherability.
Description
The invention belongs to a kind of new coating, be widely used at aspects such as automobile, pressurized vessel, electronic product, aircraft, decoration building, food sanitation, furniture, boats and ships, submarines.
The polyurethane paint that China produces at present is the aromatic urethane lacquer and imitates enamel paint.The structure of this polyurethane paint is stable inadequately, is easy to decompose aging, and barrier propterty is low, and uvioresistant not is so be generally used for the furniture industry.
The objective of the invention is to develop the senior enamel paint of a kind of new Polyurethane, it has Stability Analysis of Structures, superior performance has good insulativity and better weather, can be widely used on the external coating of national defence, capital construction, chemical anticorrosion, mechanical electric apparatus, vehicle, boats and ships, pressurized vessel.
The present invention is achieved in that and adds a certain amount of vibrin that in urethane resin Synolac, polyester ether and hydroxy acryl acid resin are formed the A component of high-grade polyurethane enamel paint; In the A of high-grade polyurethane enamel paint component, also need add a certain amount of various pigment, as the dark green G of titanium dioxide, phthalocyanine blue B, phthalein, 3132 bright red, lithol red, diarylide yellow, medium chrome yellow medium yellow and ultramarine etc.Pigment is selected the material that must accomplish to select for use fast light, heat-resisting, sun-proof, acid and alkali-resistance chemistry steadiness for use.Therefore the granularity of pigment, needs correct grinding to these raw materials more than 320 orders.In addition, in the production process of high-grade polyurethane enamel paint, also to add a certain amount of to the anti-heavy effective auxiliary agent-titanate coupling agent of colo(u)rant dispersion.Also need add a certain amount of defoamer, make its de-bubble in process of production, in use can improve the enamel paint flow leveling.Precipitate, film be full of cracks and raising anti-uv-ray also need add a certain amount of subsidiary material, in case also need add certain amount of solvent, filler and other subsidiary material.
Meanwhile, the B component of forming high-grade polyurethane enamel paint with a certain amount of tolylene diisocyanate, three methanol-based propane affixtures and biuret.
During use, mix well the back and apply as long as A component and B component cooperated by a certain percentage, easy to use, operation easily.
The present invention-high-grade polyurethane enamel paint is a kind of two-pack new coating in the industry.In use, it is stood by polyisocyanic acid base component and hydroxy component reaction and is unified into film, contains a large amount of amino acid fat keys, dibasic acid esters key, ehter bond, unsaturated double-bond, biuret linkage and allophanic acid ester bond in filming, and makes its physicals, good mechanical property.Hard, the strong adhesion of paint film is difficult for staiing, and is wear-resisting.Light, bright in colour plentiful, enamel texture is strong.Ventilation property is low, ambient temperature curable.Chemical stability is good, water-fast, oil resistant, alkaline-resisting and other chemical substance, and better weather is arranged.Therefore, be widely used on the external coating of equipment such as national defence, capital construction, Chemical Preservation, mechanical electric apparatus, vehicle, boats and ships, pressurized vessel.
Accompanying drawing 1 is technological process of production figure of the present invention.
1, mixed processes
Mix with the various types of resins of outsourcing and the auxiliary agent of preparing through pigment, filler and the process of super-dry processing.
2, grinding step
Said mixture is sent into meticulous ball mill to be ground.Grinding element is ceramic material in the barrel of ball mill and the tube.Grinding step need guarantee that all material fineness reach more than 320 orders, thereby operation meticulously.
3, filtration, purification operation
Work in-process behind the above-mentioned correct grinding are poured out carry out filtration, purification, make to obtain purified product.
4, color matching operation
In the color matching operation, need at first determine the tone range desiring to mix colours, the essential tone of color is which kind of color is main, which kind of is auxilliary, and various ratios how much, then will deliver to the toning operation by the product of filtration, purification and mix colours, order is to dark, up to reaching requirement by light color.
5, preparation B component
With a certain amount of tolylene diisocyanate, three methanol-based propane affixtures and biuret preparation B component, after mixing, get final product barrelling as finished product.
6, packaging process
Will through the color matching the barrelling of A component as finished product, can pack and dispatch from the factory.Equally, the B component of barrelling is dispatched from the factory after also can packing.
The high-grade polyurethane enamel paint sampling send coating quality supervision and inspection center of country of Changzhou the Ministry of Chemical Industry to detect; Sampling send Huaihua product quality supervision and inspection station, Hunan Province to detect again; Sampling send Hunan Province chemistry painting industry quality supervision and test granting station complete detection again, and all physical and chemical indexs all meet the enterprise product quality standard.Following table is listed high-grade polyurethane enamel paint and several lacquer kind performance comparison situation.
High-grade polyurethane enamel paint and other lacquer kind of performance comparison table
High-grade polyurethane enamel paint is widely used in machinery, electronics, automobile industry.The Changsha medium-sized station wagon of millionaire board all uses high-grade polyurethane enamel paint.Wherein a collection of product is sold to Xinjiang province, has a Russian client of quilt to buy when selling, and causes the product sales volume of Changsha automobile factory to heighten.When the light car of HK6600 type that the Huaihua bus factory produces had used high-grade polyurethane enamel paint (selecting colors such as beautiful grey, dark brown, light brown, orange for use) participation Kunming automobile fair in 94 year spring, the product surface application was subjected to client's favor, and output, sales volume straight line rise.When south, Zhuzhou motor depot adopts 125 types, the 750 type motorcycles of high-grade polyurethane enamel paint application to participate in Guangzhou Export Commodities Fair exhibition, also be subjected to user's welcome.We can say that the high-grade polyurethane enamel paint product performance are stable, reliable, market outlook are wide, and competitive power is strong, has good social benefit and economic benefit.
