Abstract
The invention provides a kind of aluminium section for buildings hydrophobic and the formula of the microstructure powder coating product of waterproof spot, including saturated polyester resin 50 60%, TGIC curing agent 3 5%, polyflon 25 35%, sand streak agent 0.1 0.5%, organobentonite 1 2%, pigment 5 10%.The present invention is a kind of powdery paints of hydrophobic.In aluminium section for buildings industry, use ordinary powder paint spraying, when using out of doors (such as exterior window), because the dust of exterior wall attachment is under rain drop erosion, aluminum alloy external window is easy to leave the dirty vestige of water, this is due to sewage spread and is trapped in the spot formed after aluminium section bar film coated surface, water evaporation.The powdery paints that the present invention is made, the coating after it solidifies is not hydrophilic, and water can be only formed water droplet in coating surface, can not be in flakes, so water droplet is flowed away rapidly under gravity, then water can not form water stain or spot in film coated surface, and the effect of water resistant spot is served to a certain extent.
Description
Technical field
The present invention relates to powder coating technology field, and in particular to a kind of aluminium section for buildings hydrophobic and waterproof spot
Microstructure powder coating product formula.
Background technology
According to water in the infiltration degree of the surface of solids, solid can be divided into hydrophily and hydrophobicity, so-called super-hydrophobic (to hate
Water) surface generally refers to be more than with the contact angle of water 150 degree of surface.For a hydrophobic surface of solids, work as table
When there is microspike in face, there are some air between water and the surface of solids, globule major part and air can be caused by " pass is arrived "
Contact, is greatly reduced on the contrary with solid direct contact surface product.Because the surface tension effects of water make water droplet in this rough surface
Shape close to spherical, its contact angle is up to more than 150 degree, and the globule can be very freely in surface scrolls.One true
Super hydrophobic surface in positive meaning should have larger static contact angle, while should more have less slide angle.It is so-called to connect
Feeler, is exactly liquid
Drop in the angle held during surface of solids formation thermodynamical equilibrium.Pass through the globule in liquid-solid-gas abutment
The terminal of curve and the contact point of the surface of solids, which are determined, to be come.Roll angle can refer to as another index for evaluating surface wettability
Be certain mass drop start in inclined plane roll critical angle.Roll angle is smaller, and what the surface of solids was shown dredges
It is aqueous better.Because the Action of Gravity Field of the earth, water droplet has the trend of downslide in the inclined surface of solids.With solid inclination angle
Become big, downslide component of the water droplet along bevel direction is also constantly increasing, when inclination angle increases to a certain critical angle, water droplet meeting
Slid from the surface of solids, critical angle at this moment is exactly roll angle of the water in such a surface of solids.Roll angle is smaller, solid table
The ultra-hydrophobicity in face is better.
In aluminium section for buildings industry, using ordinary powder paint spraying, when using out of doors (such as exterior window), due to exterior wall
The dust of attachment under rain drop erosion, aluminum alloy external window be easy to leave water it is dirty-vestige, this is due to sewage spread and delay
The spot formed after aluminium section bar film coated surface, water evaporation.
The content of the invention
For the deficiencies in the prior art, it is an object of the invention to provide one kind is rational in infrastructure, easy to use one
The formula of kind of aluminium section for buildings hydrophobic and the microstructure powder coating product of waterproof spot, it solves above-mentioned these
Problem.
The technical solution adopted in the present invention is as follows：A kind of microstructure of aluminium section for buildings hydrophobic and waterproof spot
The formula of powder coating product, including saturated polyester resin 50-60%, TGIC curing agent 3-5%, polyflon 25-
35%, sand streak agent 0.1-0.5%, organobentonite 1-2%, pigment 5-10%.
Preferably, this product surface forms hydrophobic microstructure, and the hydrophobic microstructure is several 5-20 microns
The projection of diameter, this to project through reduction surface tension, it is improved and the contact angle of water is limited, can about be improved to 1200, its
Surface contact angle can reach 170-175 degree.
Preferably, all material is put into high speed material-compound tank and mixed 5~7 minutes, double spiral shells will be transferred to mixed material
Bar extruder hopper, hot milling is extruded under the conditions of 110~120 DEG C, and making various materials, further engagement is uniform, then through broken pressure
The cooling of piece machine, coarse crushing, are transferred to the powder that average grain diameter is crushed in impact type grading mill for 30um or so, through high speed rotary screen
Sieving packaging.
Preferably, the hydrophobic raised structures of some nanoscales, the hydrophobic raised structures of nanoscale are distributed with the projection
It is a diameter of 100-200 nanometers.
Preferably, decorative pattern diffusant 0.1-0,3%, nano level metal powder filler 0.1-0.3%, gold are also included in formula
Belong to powder binding auxiliary agent 0.1-0.6%, the nano level metal powder filler particles are a diameter of 50-100 nanometers.
Beneficial effects of the present invention include：
The present invention is a kind of powdery paints of hydrophobic.In aluminium section for buildings industry, using ordinary powder paint spraying,
When open air is used (such as exterior window), because the dust of exterior wall attachment is under rain drop erosion, aluminum alloy external window is easy to leave water dirt
Vestige, this is due to sewage spread and is trapped in the spot formed after aluminium section bar film coated surface, water evaporation.The powder that the present invention is made
Last coating, the coating after it solidifies is not hydrophilic, and water can be only formed water droplet in coating surface, it is impossible in flakes, then in gravity
In the presence of water droplet flow away rapidly, then water can not form water stain or spot in film coated surface, and water resistant is served to a certain extent
The effect of spot.This powdery paints is applied on aluminium section for buildings prospect very much.
For it is modern high increase building for, the cleaning of exterior window is relatively difficult, and this hydrophobic with self-cleaning performance and
The aluminium section bar of the powder coating and their application of waterproof spot, which is used for external window of building, will substantially reduce the cleaning amount of exterior window.
