Abstract
The invention discloses a kind of powder solar heat reflection paint, it is characterized in that: calculate by mass percentage, this powder solar heat reflection paint is made up of vibrin, solidifying agent, promotor, nano silicon, pigment, filler, anti-yellowing change agent, st-yrax, flow agent, antioxidant, anti-hard caking agent and defoamer; First preparation method for adding in high-speed stirring mixer by polyester resin powder, solidifying agent, promotor, pigment, filler, anti-yellowing change agent, st-yrax, flow agent and antioxidant precise batching; Then pre-mixing material twin screw extruder is carried out melt extruding mixing and compressing tablet cooling fragmentation for twice; Again second time is melt extruded the broken and classification of mixing and the broken material of cooling and anti-hard caking agent, defoamer air classifying abrasive dust; Finally increase substreams with cyclonic separator to be separated and to get final product.The present invention not only film adhesion is good, and physical strength is high, and has solar heat reflection function.
Description
Technical field
The invention belongs to technical field of coatings, relate to a kind of powder solar heat reflection paint and preparation method thereof.
Background technology
The research of solar heat reflection paint is long-standing, however more common be in the market water-based or oil-based solvent type heat reflection coatings.Traditional low-solid content solvent based coating is in the manufacture of coating, construction, drying, film-forming process, VOC is given out in air, very serious pollution is caused to ecotope, and the film forming mechanism of coating is molecule crosslinked film forming after solvent evaporation, can cause film adhesion like this, physical strength is poor.
Powder coating be one containing organic solvent, by means of air as dispersion medium, the coating of application is carried out with powder morphology, the impact that the application of powder coating is not bullied gentle season, powder coating technique ratio is easier to grasp, not easily there is sagging, the disadvantages such as foaming, easily implement automatic assembly line application.And there is the high and low power consumption and other advantages of Reuse of materials rate, obtain global concern in recent years.
Summary of the invention
The object of the invention is to, provide a kind of film adhesion good, physical strength is high, and has the powder solar heat reflection paint of solar heat reflection function.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of powder solar heat reflection paint, calculate by mass percentage, be made up of polyester resin powder 55-65%, solidifying agent 5-7%, promotor 0-1%, nano silicon 0.2-1%, pigment 10-25%, filler 5-10%, anti-yellowing change agent 0.1-0.5%, st-yrax 0.3-0.5%, flow agent 1-2%, antioxidant 0.3-1%, anti-hard caking agent 0.3-0.8% and defoamer 1-1.5%.
Vibrin is made up of one or both in oh type vibrin, carboxyl-type polyester resin or silicone modified polyester resin.
Solidifying agent is polyester resin solidifying agent.
Polyester resin solidifying agent is made up of one or more in triglycidyl isocyanurate, hydroxyalkyl bisamide, dead front type aliphatic isocyanates or solidification aminoresin.
Pigment is Rutile type Titanium Dioxide.
Filler is barium sulfate.
First starting material pre-mixing is carried out headed by a kind of preparation method of powder solar heat reflection paint, to add in high-speed stirring mixer after vibrin, solidifying agent, promotor, pigment, filler, anti-yellowing change agent, st-yrax, flow agent and antioxidant precise, with 600 ~ 800 r/min high-speed stirring mixing 10 ~ 15min; Then pre-mixing material twin screw extruder is melt extruded mixing and compressing tablet cooling fragmentation, the rotating speed melt extruding mixing is 40 HZ, temperature is 100 ~ 120 DEG C, and first time melt extrudes mixing and the broken Recycle of material of compressing tablet cooling and carries out second time and melt extrude mixing and compressing tablet cools fragmentation; The material and anti-hard caking agent, defoamer air classifying mill (plektron pin) that second time are melt extruded mixing and cooling fragmentation are pulverized and classification again, the main mill rotating speed of air classifying mill is 40HZ, classifier rotating speed is 30HZ, classifier spacing is 60 ~ 80 μm, guarantees that the particle diameter of 55% powder is 20 ~ 40 μm of scopes; Finally increase substreams with cyclonic separator, blast is 0.3-0.7MPa, makes fine powder content less than 5% in powder, to obtain final product.
