Specific embodiment
In order to illustrate more clearly of the present invention, below with reference to preferred embodiment, the present invention is described further.Ability
Field technique personnel should be appreciated that following specifically described content is illustrative and be not restrictive, this should not be limited with this
The protection scope of invention.
In the case of being clear from, explaining to the purpose of the present invention by following embodiment, the component of the coating is equal
It is released using parts by weight as the universal standard bright.In the absence of special instructions, for simplicity, described in the embodiment of the present invention
" part " and parts by weight meaning having the same.
Appliance finishes are made of resin, pigments and fillers, auxiliary agent and four part of solvent, for this characteristic of high temperature resistant, the present invention
Mainly optimized from the temperature tolerance of resin, pigments and fillers, auxiliary agent.
Resin: modified organic silicone resin and polyester resin, pigments and fillers: heat-resistance type inorganic color stuffing, as titanium dioxide, carbon black,
Metallic pigments, blanc fixe etc..
Modified organic silicone resin temperature tolerance explanation: the basic framework of organic siliconresin is the main chain of Si-O, and bond energy is compared with C-C
The bond energy of key is high, and simple warm-up movement is difficult to be broken Si-O key, thus its to heat, the stability of oxygen than general polyester resin
It is much higher, there is preferable high temperature resistance.The resin also has excellent weatherability, cold resistance and the property such as resistant to chemical etching
Energy.With following advantage and disadvantage: after the coating film forming of modified organic silicone resin, with temperature tolerance is strong, hardness is high, corrosion resistance is strong
The advantages that, at the same its there is also following disadvantages: with the ply adhesion of priming paint is poor, poor in processability (T curved > 2T), paint film ductility
Difference is unfavorable for deep processing.
The shortcomings that for modified organic silicone resin, is optimized by following measure:
The parts by weight or weight percent ratio of modified organic silicone resin and polyester resin are adjusted, i.e. addition gamma transition temperature
The polyester resin that Tg is low, molecular weight is big is spent to promote the processability after film forming；It is attached with priming paint to increase to add silane coupling agent
Put forth effort.
Influence of the different proportion of modified organic silicone resin and polyester resin to performance is as follows:
Polyester resin and modified organic silicone resin different proportion are 100%, 75%, 55%, 35%, and adhesive force increases, is resistance to
Solvent borne increase, heat-resisting xanthochromia reduce, red hardness increase, it is contemplated that the harmony of coating comprehensive performance, polyester resin with change
Property organic siliconresin ratio control 55%.
Amino resins selects full methyl-etherified class amino resins as crosslinking agent, and advantage is that flexibility is good after forming a film, and paint film causes
Close property is strong.
The case type acid catalyst of catalyst choice, on the one hand can promote storage stability, on the other hand be also beneficial to apply
The temperature tolerance of material.
The selection of dispersing agent: dispersant adsorption generates charge repulsion or steric hindrance on the surface of pigment, prevents pigment
Flocculation is generated, dispersion is made to be in stable state.In view of the wetting and dispersing effect and heat-resisting quantity to pigments and fillers, selection
Polymeric polycarboxylic acid dipersant with active function groups, it has both wetting and peptizaiton, and absorption on the surface of the pigment, is inhaled
Membrane is thicker, improves the stability of pigment dispersion, prevents pigment from returning the requirement for slightly having reached storage stability.
The selection of defoaming agent: coating can generate a large amount of foam in the whipping process before use, it is necessary to defoam.Consider to apply
Expect needs resistant to high temperature, selects modified silicone to make defoaming agent, work well.
The selection of levelling agent: due to containing modified group and organosilicon radical, the surface of the two in modified organic silicone resin
Tension is different, and the surface tension of organosilicon is smaller than modified group, and this surface tension unevenness is easy to produce shrinkage cavity, in order to disappear
Except shrinkage cavity, improve the levelability of coating, on the one hand such as mixes dibasic ester, adjustment solvent evaporation speed using higher boiling mixed solvent
Degree reduces viscosity, extends flow time；On the other hand, consider from compatibility and heat-resisting quantity, determine to use organic silicon levelling
Agent.
The selection of adhesion promoter: in view of adhesion between layers and with the compatibility of coating system, select silane
Coupling agent promotes adhesive force.
Nylon acid dimethyl ester DBE is purchased from E.I.Du Pont Company；Propylene glycol methyl ether acetate is purchased from along training Chemical Co., Ltd..
