Abstract
The invention discloses a water-boiling-resistant powder coating which comprises 65-75% of polyester resin, 5-8% of curing agent, 20-30% of kaolin, 1-1.5% of leveling agent, 1-1.5% of brightener, 0.5-1.0% of benzoin and 0.5-1.0% of carbon black. The powder coating produced according to the formula has the advantages that: 1, the water boiling resistance is improved to 25 hours at 95 DEG C from 10 hours at 60 DEG C of common powder coating, and the coating surface does not change after a long-time water boiling test; and 2. weather resistance test is improved to 1,200 hours from 500 hours of common powder and the coating still does not fade or age.
Description
Technical field
The present invention relates to a kind of powder coating, relate in particular to a kind of water boiling resistance powder coating.
Background technology
Powder coating with its economy, environmental protection, efficient and performance brilliance etc. a bit, substituting organic solvent type coating just gradually becomes the important development direction in the coating industry, is keeping rate of growth faster always.The also excellent together weather resistance of powder coating metal building material, ornamental and characteristics such as shape is widely used in all respects of buildings.Since early 1970s, powder coating came out, its application aspect metal building material increased rapidly.In the application of metal building material, representative powder coating kind has epoxy resin, vibrin, vinyl resin powder coating etc.As application, like the metal building material of high preservative property such as part metals framework, door and window, balcony, corridor, partition plate, great majority only adopt polyester, acrylic powder coating.Because be to be used for outdoor application and decoration, often expose to the sun and rain, also require paint film also will have the excellent water tolerance ability, rainwater soaks and flushing also will have good gloss retention ability, and coating is non-foaming, and is colour-fast basically.Cause the reason of water tolerance variation of powder coating mainly relevant with the state of cure of powder coating and the filler of selecting for use thereof, auxiliary agent.Vibrin is one of critical material wherein in the weatherable polyether powder coating, and the molecular structure of vibrin, active function groups and auxiliary agent directly have influence on the water resistance of powder coating coating to the state of cure important influence of powder coating.
Lot of documents has reported that polyvalent alcohol becomes the method for vibrin with polyprotonic acid direct polymerization under the condition of organotin catalysts, but the special vibrin patent report of using to the water boiling resistance performance of improving powder coating is few.U.S. Pat 5869567 has reported that a kind of acid number is the compound method of the polyester resin for powder coating of 10-40mg KOH/g, and this patent summary is referred to the water-proof factor of influence, and is unspecified.Chinese patent 1962717 discloses the preparation method of a kind of mixed polyester resin (60: 40), and this patent has compared the influence of different monomers to poach, mainly adopts the method for part hexanodioic acid, m-phthalic acid and trimellitic acid 1,2-anhydride synthesizing polyester resin.
Summary of the invention
The present invention provides technical problem to be solved to provide a kind of water boiling resistance powder coating, mainly is made up of vibrin, solidifying agent and kaolin, has higher water boiling resistance property and weathering resistance.
The present invention realizes through following technical scheme: a kind of water boiling resistance powder coating, the component and the mass percent of said water boiling resistance powder coating are following
Vibrin 65～75%
Solidifying agent 5～8%
Kaolin 20～30%.
Above-mentioned water boiling resistance powder coating also comprises in the said water boiling resistance powder coating:
Flow agent 1～1.5%.
Above-mentioned water boiling resistance powder coating, said flow agent are selected from organic silicon modified by polyether, polyester modification organosilicon, polyacrylic ester, propylene soda acid and hold resin, YSR 3286, PSI, in the organic radical modified polyorganosiloxane one or more.
Above-mentioned water boiling resistance powder coating also comprises in the said water boiling resistance powder coating:
Glossing agent 1～1.5%.
Above-mentioned water boiling resistance powder coating also comprises in the said water boiling resistance powder coating:
St-yrax 0.5～1.0%.
Above-mentioned water boiling resistance powder coating also comprises in the said water boiling resistance powder coating:
Carbon black 0.5～1.0%.
Above-mentioned water boiling resistance powder coating, said solidifying agent are one or more in vinyl triamine, aminoethyl piperazine, methylene-bis hexamethylene alkanamine, diethylenetriamine, the triethylene tetramine TEPA.
Because solidifying agent can better react with vibrin in this formulation for coating material; Reactive behavior is higher; Increased cross-linking density; And in this product, increased hard fillers such as kaolin again, thus improved the water boiling resistance performance, so having than traditional product, this product has better water boiling resistance and weathering resistance.
The powder coating that adopts above-mentioned prescription to produce has following advantage:
1. the water boiling resistance performance rose to 95 degree 25 hours in 10 hours from 60 degree of conventional powder coating, and long-term poach testing coating surface is no change still.
2. can 500 hours of conventional powder be promoted to 1200 hours aspect the weathering resistance test, coating does not still have the catabiosis of fading.
