Abstract
The present invention relates to thermosetting coating, its component and weight percent as follows: Synolac 40-50%, aminoresin 18-20%, auxiliary agent 3-5%, surplus are solvent.Described solvent be with dimethylbenzene, aromatic hydrocarbons, trimethylbenzene, durene by weight ratio 1.5:0.5:1:1 mix.Described auxiliary agent comprises one or more of siccative, toughner, defoamer, flow agent, dispersion agent, anti-settling agent etc.Thermosetting coating of the present invention has carried out effective adjustment to coating internal chemical structure, molecular structure, and the molecule content of coating, between 15000-30000, makes paint coatings sticking power improve, has stronger bonding strength.
Description
Technical field
The present invention relates to a kind of coating, be specially a kind of Synolac and aminoresin is the thermosetting coating of main body, be suitable for bike external ornament sprays.
Background technology
Thermosetting coating is not because it is containing organic solvent, and the feature of environmental protection is good, and utilization ratio is high, and the advantages such as storage, convenient transportation are widely used in each field.On bike external ornament, usually need to spray thermosetting coating, expose to prevent bike and produce the problem such as depainting, crackle in the sun.In prior art, thermosetting coating usually there will be the problems referred to above because of adhesion problem.
Summary of the invention
Technical problem to be solved by this invention is to provide the high thermosetting coating of a kind of sticking power.
For solving the problems of the technologies described above, the invention provides a kind of thermosetting coating, its component and weight percent as follows: Synolac 40-50%, aminoresin 18-20%, auxiliary agent 3-5%, surplus are solvent.
Described solvent be with dimethylbenzene, aromatic hydrocarbons, trimethylbenzene, durene by weight ratio 1.5:0.5:1:1 mix.
Described auxiliary agent comprises one or more of siccative, toughner, defoamer, flow agent, dispersion agent, anti-settling agent etc.
The preparation method of above-mentioned thermosetting coating is as follows:
(1) by dimethylbenzene, aromatic hydrocarbons, trimethylbenzene, durene by weight ratio 1.5:0.5:1:1 be mixed into solvent;
(2) Synolac, aminoresin and solvent are stirred, and adopt spray method to add each analog assistant; When temperature reaches 10 DEG C, without the need to heating, stirring 10-15 minute is configurablely form this thermosetting coating, when temperature is below 10 DEG C, and can heated and stirred.
Technique effect of the present invention: thermosetting coating of the present invention has carried out effective adjustment to coating internal chemical structure, molecular structure, the molecule content of coating, between 15000-30000, makes paint coatings sticking power improve, has stronger bonding strength.
Embodiment
Embodiment 1

(2) Synolac, aminoresin and solvent are stirred, and adopt spray method to add each analog assistant; When temperature reaches 10 DEG C, without the need to heating, stirring 15 minutes is configurablely form this thermosetting coating, when temperature is below 10 DEG C, and can heated and stirred.
On the basis of above-described embodiment, can mix colours according to one or more mill bases of the color selecting of colored paint, the pigment of red, yellow, and green, orchid, purple, the different colours such as black can be selected.
Sticking power detects: sticking power, by hot and cold facture, after first paintings test plate (panel) being boiled 15 minutes in 100 DEG C of boiling water, then will to be coated with in refrigerated tank that test plate (panel) puts into-20 DEG C maintenance 15 minutes, finally etc. painting test plate (panel) separate at normal temperatures cold after carry out cross cut test; Cross cut test refers to the measuring method that standard GB/T/T9286-1998 " cross cut test of paint and varnish paint film " specify.This standard adopting by equivalent international standard ISO2409:1992.The standard specifies when penetrating into ground with cartesian mesh pattern cut coating, evaluate a kind of experimental technique of the resistance that coating departs from from ground.Test-results is divided into 0 ~ 5 grade, and 0 grade stands intact, and after testing, the paint adhesion of the application is 1 grade, is therefore better than 3 to 4 grades of prior art.
Moire detects: will be coated with test plate (panel) and pass through after cold-heat treatment, and put 2-3 hour at normal temperature, and after testing, painting test plate (panel) is flawless, without moire.
