Description
Technical field
The invention belongs to applied chemistry field, relate to a kind of insullac, particularly relate to a kind of acid modified alcoholic amino insullac and system thereof
Preparation Method.
Background technology
Coating has the history of thousand of years, and it is a kind of multifunctional material, is coated in object surface and plays protection, decorates, indicates
And give the effects such as specific function.From the point of view of the history of coating, before more than 4,000 years, China just uses the sky such as Oleum Verniciae fordii and Resina Toxicodendri verniciflui
So material be raw material to make coating products, coating products kind in early days is single, and range of application has certain limitation, along with
Industrial expansion, the mankind start according to self needs, use various synthetic to make coating, and coating products there occurs huge
Big change, not only classification is various, and Various Functions, coating is widely used and develops.At present, coating products is
Through applying the various aspects in productive life, relate to multiple industries such as automobile anticorrosion, electric insulation, house decoration, military science and technology
And field, the research and development of coating increasingly come into one's own, it may be said that coating with the development of national economy, national science and technology
Prosperity, the raising of living standards of the people has close contact, and it is existing that the level of coatings industry even has become as one country of measurement
One of mark of generationization.
Coating in early days, mainly with natural materials as raw material, prepares paint by relatively simple process, and modern coatings raw material
Complexity, is mainly made up of film forming matter, pigment and three components of solvent, and adds a small amount of auxiliary agent according to actual needs, as dry in urged
Agent, defoamer, levelling agent, antisettling agent, corrosion inhibiter etc..
In coating, film forming matter divides mineral-type and organic, and mineral-type film forming matter uses less, and conventional has silicate, and organic becomes
Film thing uses widely, is mostly some low polymers, such as drying oil, lacquer, synthetic polymer etc., these polymer
All possess a feature: be low polymer before film forming, after film forming, then form polymeric film by certain chemical reaction, poly-
Adduct molecule chain is changed into build by line style.Some coating can also thermoplastic polymer be film forming matter, and solvent volatilization gets final product film forming,
There is not chemical change in polymer, such as chlorinated rubber paint.Film forming matter is the most important composition of coating, and its character directly determines to be coated with
The effect of material.Coating by film forming species can be divided into natural resin paint, alkyd resin coating, amino resin coatings, acrylic resin paint,
Epoxy resin coating, polyurethane, elementary organic paint and rubberbase paint etc., wherein alkyd resin be develop the earliest, synthesis that yield is maximum
Lacquer type organic coating, was once up to 90% in Coating Market occupation rate, and according to statistics, within 1997, national coating total output is 135 × 104T, its
Middle alkyd resin accounts for 52.9%, occupies first of synthetic resin.Alkyd resin, since exploitation, has occupied weight in coatings industry always
The status wanted, because of its abundant raw material source, product variety is many, facilitate chemical modification, is still a kind of important coating tree at present
Fat.
In solvent-borne type insullac, volatile organic content is high, and serious environment pollution, along with enhancing and the environmental protection of environmental protection consciousness
Being gradually improved of regulation, the mankind are more and more higher to the performance requirement of insullac, and low volatile organic or non-volatility Organic substance are exhausted
The research and development of edge paint receive significant attention.The dipping that alkyd resin is widely used to middle-size and small-size low voltage motor electrical equipment as insullac is exhausted
Edge processes, and wherein, aqueous alkide resin is lower than the relative molecular mass of corresponding solvent type resin, and dried coating film is slow, hardness
Low, poor water resistance, corrosion-resistant, weatherability are the best.
Summary of the invention
Present invention solves the technical problem that: in order to overcome defect of the prior art, it is thus achieved that a kind of dried coating film is fast, hardness is high,
