Description
Technical field
The present invention relates to powder coating technology field, particularly relate to a kind of powdery paint for aluminum profile.
Background technology
Powder coating has solvent-free property, non-environmental-pollution, Powder Recovery and utilization ratio high, is utilized widely.Powder coating can be divided into the large class of thermoplasticity, thermoset two.Thermoplastic powder coating is using thermoplastic resin as filmogen, its feature is that synthetic resins raises and deliquescing with temperature, and after cooling, become hard, this process can be carried out repeatedly repeatedly, often changing once will be progressively aging, finally becomes the powder of non-plastic.Thermosetting powder coating(s) is using thermoset synthetic resin as filmogen.Its feature is with some prepolymer resin compared with low polymerization degree, in the presence of a curing agent through the baking-curing of certain temperature, and becomes and can not dissolve or the scleroid final product of melting.When temperature is when raising, product can only decompose and can not soften again, belongs to chemical transformation.Because molecular resin amount is low, so have good levelling property, wettability, firmly can adhere to surface of workpiece, and have ornamental and non-corrosibility preferably after solidification.But be that to be used as decorative coating in the majority all the time at China's powder coating.
The patent No. is point out along with the demand of various countries to the energy is increasing in CN201510396989.7 " a kind of new type low temperature cured epoxy powder coating " patent, reduce energy consumption, protection of the environment becomes the main body of enterprise development, exploitation cold curing paint is that the universal powder coating solidification temperature of solution is higher, narrow application range, the important method that energy consumption is large, it utilizes bisphenol A type epoxy resin and the good compatible feature of modified crosslinking agent, coating is made to have excellent sticking power, shock-resistant, the advantages such as wet-heat resisting, filler adopts process white and active micro silicon powder to make coating have good acid resistance and alkali resistance, but the powder coating inventing preparation thus can not meet corrosion, antibacterial and protection field demand.The present invention has low solidification value by the powder coating that rational formulating of recipe obtains, expand application prospect, and study on the modification is carried out to resin matrix, the corrosion-resistant, weather-proof, antibacterial of powder coating and physical strength etc. are improved, meet the requirement for decoration and protection field each side on market.
Summary of the invention
The object of the invention is exactly the defect in order to make up prior art, provides a kind of powdery paint for aluminum profile.
The present invention is achieved by the following technical solutions:
A kind of powdery paint for aluminum profile, is made up of the raw material of following weight part: ammonium polyphosphate 3-4, dibutyitin maleate 1-2, tetramethoxymethylglycoluril 1-3, PTMG 3-4, magnetic iron powder 7-8, light calcium carbonate 14-16, ferric oxide 2-3, sorbitan monooleate 0.6-0.8, carboxymethyl cellulose 2-3, adipic dihydrazide 4-5, urethane resin 10-12, polyxyethylated alkylphenol 0.3-0.4, epoxy resin 84-95, resol 6-8, Vaseline 1-2, rare earth chloride 0.1-0.2, chitosan 15-18, polyvinyl alcohol 4-5.
Described a kind of powdery paint for aluminum profile, be made up of following concrete steps:
(1) dissolved with whose of 10-12 times amount by carboxymethyl cellulose, then it is even to add sorbitan monooleate and ferric oxide ultrasonic disperse, low-grade fever is stirred to that to form dope for subsequent use;
(2) product prepared by step (1) is coated on the surface of magnetic iron powder, add heat extraction solvent, crushed after being dried becomes micro mist for subsequent use;
(3) chitosan is dissolved in the acetic acid solution of 85%, it is 6-10% chitosan solution that magnetic agitation evenly makes concentration, polyvinyl alcohol water dissolution being made concentration is 8-10% solution, be heated to 80-85 DEG C, then chitosan solution is added in polyvinyl alcohol water solution, add product ultrasonic disperse prepared by step (2) more even, standing and defoaming obtains spinning solution;
(4) by resol and rare earth chloride mixing, heated and stirred reaction 10-15min, when temperature of reaction is at 80-85 DEG C, constant temperature keeps 10-15min, then boiling is heated to, under boiling state, keep 3-4h, naturally cool to room temperature, then make with the alcohol dilution of 75% novolac solution that concentration is 10-12%, be added to mixing and stirring in product prepared by step (3) again, obtain conjugated fibre through electrostatic spinning process for subsequent use;
(5) product epoxy resin, urethane resin, adipic dihydrazide and step (4) prepared drops in high mixer and stirs, by all the other surplus stock mixing flour to 100 orders, continue to drop in high speed machine and stir, finally by mixing material after 70-80 DEG C of preheating melting mixing 20-30min, be cooled to room temperature, be ground into the powder that particle diameter is 20-35 μm again, finally carry out metering packing, discharging.
Advantage of the present invention is: the present invention utilizes rare earth chloride volatile de-electronation reactive behavior high, generates extremely strong chemical bond, make it heat-resisting with reactive modified phenolic resin, the performances such as wear-resisting and erosion resistance are improved, and utilize chitosan itself nontoxic, the features such as broad-spectrum antimicrobial and modified phenolic resins, filler is blended prepares conjugated fibre, utilizes conjugated fibre and substrate ring epoxy resins generation copolymerzation with cross-linking to react, adds the cross-linking density of system, improve film media-resistant penetrating power, its water-intake rate is reduced, and resistance to cracking is improved, and also improves the corrosion-resistant of powder coating simultaneously, the performances such as antibacterial and toughness, improve the shortcoming that the easy crisp period of storage easy to crack of epoxy resin itself is not grown, the ferric oxide of interpolation, magnetic iron powder and light calcium carbonate etc. significantly improve the wear-resisting of powder coating, super corrosion-resistant, acidproof, weatherproof performance, the solvent-free environmental protection of the product that the present invention obtains, coating surface flat smooth, also has intensity high, thermal insulation is good, glossiness is high, the feature that sticking power is good, has a good application prospect for aluminium section bar.
