Wherein, described water-based fluorocarbon resin is according to the ratio system that weight ratio is 3:4 by CTFE and tetrafluoroethylene monomer ?.
In technique scheme, more specifically scheme is it may also is that the percentage by weight of described constituent is: water-based fluorocarbon Resin 75%, aminopropyl trimethoxysilane 0.1%, tetramethyl piperidine 0.4%, levelling agent 0.1%, dispersant 0.2%, wetting agent 0.1%, defoamer 0.2%, light stabilizer 0.2%, coalescents 6%, surplus is water.
Further, the percentage by weight of described constituent is: the percentage by weight of described constituent is: water-based fluorocarbon Resin 86%, aminopropyl trimethoxysilane 0.3%, tetramethyl piperidine 0.2%, levelling agent 0.3%, dispersant 0.4%, wetting agent 0.3%, defoamer 0.4%, light stabilizer 0.1%, coalescents 8%, surplus is water.
The two of the technical problem to be solved are to provide the preparation of the water-thinned antirust primer of a kind of good combination property Method.
In order to solve the problems referred to above, the technical solution adopted in the present invention is:
Use the raw material of following percentage by weight:
Water-based fluorocarbon resin 75%～86%, aminopropyl trimethoxysilane 0.1%～0.3%, tetramethyl piperidine 0.2%～0.4%, stream Flat agent 0.1%～0.3%, dispersant 0.2%～0.4%, wetting agent 0.1%～0.3%, defoamer 0.2%～0.4%, light stabilizer 0.1%～0.2%, coalescents 6%～8%, surplus is water；
Wherein, described water-based fluorocarbon resin is according to the ratio system that weight ratio is 3:4 by CTFE and tetrafluoroethylene monomer ?；
Its manufacture method comprises the steps:
A, first by water, dispersant, wetting agent, defoamer weigh put in reactor, start blender at 400 revs/min～600 Rev/min mixing speed under stir more than 15 minutes so that it is stir；
B, stir after, under the mixing speed of 400 revs/min～600 revs/min add water-based fluorocarbon resin, continue stirring 10 More than minute；
C, keep adding under the mixing speed of 400 revs/min～600 revs/min coalescents, continue stirring 10 minutes～15 minutes, Rear addition aminopropyl trimethoxysilane, tetramethyl piperidine, levelling agent, light stabilizer, continue to be stirred until homogeneous.
In technique scheme, used by CTFE and tetrafluoroethylene monomer according to the ratio that weight ratio is 3:4 The water-based fluorocarbon resin that example prepares has raising stain resistance, weatherability, the effect of chemical-resistant；Aminopropyl trimethoxy silicon Alkane has holding film non yellowing, the effect of nondiscoloration；The nanoscale that tetramethyl piperidine has absorption UV-A and UV-B simultaneously is wide Spectrum ultraviolet, thus improve weather-proof, the effect of ageing-resistant performance of product.
Owing to using technique scheme, there is advantages that
