CN104449256A - Thin-film heat-reflection heat-insulation anticorrosive paint - Google Patents

Abstract

The invention discloses a thin-film heat-reflection heat-insulation anticorrosive paint which comprises the following components in percentage by weight: 33-35% of saturated polyester, 5-10% of solvent, 0.5-1.0% of wetting agent, 1-2% of dispersing agent, 0.2-0.3% of defoaming agent, 0-1% of pH regulator, 20-40% of filler and 5-10% of hollow microbead. The paint is prepared by the following steps: sequentially adding the solvent, dispersing agent, wetting agent, defoaming agent and other assistants into a high-speed dispersing agent at the rotation speed of 400-600 r/min, adding TiO2, increasing the rotation speed to 3000 r/min to perform high-speed dispersion for 30 minutes, testing the particle size of the pigment and filler by using a Hegman fineness gauge until the maximal particle of the pigment and filler reaches 60 mu m, lowering the rotation speed of the rotor to 400 r/min, adding the saturated polyester and hollow microbead, and regulating the viscosity with a diluter to obtain the paint. The thin-film heat-reflection heat-insulation anticorrosive paint has the advantages of favorable heat-insulation effect, favorable T-bend performance, favorable salt-fog resistance and favorable artificial weathering resistance.

Description

Thin layer heat-reflecting heat-insulating protective system

 

Technical field

The invention belongs to protective system, be specifically related to a kind of thin layer heat-reflecting heat-insulating protective system.

 

Background technology

Metallic substance occupies critical role with its excellent mechanical property and processing performance at Material Field, but metallic corrosion also causes massive losses to human society, and therefore developing efficient protective system, to carry out protection to it be the simplest method.And metal is in long-term use procedure, on the one hand because being damaged by corrosion by the chemistry of surrounding medium or electrochemical action for a long time, hidden danger can be brought because of intensification of absorbing heat summer on the other hand.Special in factory building and warehouse, because usable floor area is comparatively large, utilize air-conditioning or spraying cooling, increase enterprise cost on the one hand, too increase the consumption of resource on the other hand.Therefore develop and integrate heat insulating and corrosion function, the coating of easy construction, meet the development trend of coating, have a good application prospect.Traditional heat preserving and insulating material improves gas phase porosity, and reduction thermal conductivity and transmissibility factor are main.Fiber-like lagging material in order to make transmission of heat by convection and radiative transfer reduce, must have thicker coating in environment for use.

 

Summary of the invention

In order to overcome the above-mentioned defect that prior art field exists, the object of the invention is to, a kind of thin layer heat-reflecting heat-insulating protective system is provided, improve heat-proof quality.

Thin layer heat-reflecting heat-insulating protective system provided by the invention, formulation weight ratio is: saturated polyester 33-35%, solvent 5-10%, wetting agent 0.5-1.0%, dispersion agent 1-2%, defoamer 0.2-0.3%, PH conditioning agent 0-1%, filler 20-40%, cenosphere 5-10%.

Preparation technology is as follows:

High speed dispersion agent, under rotating speed 400-600r/min condition, adds the auxiliary agents such as solvent, dispersion agent, wetting agent, defoamer successively, at interpolation TiO ₂after, improve rotating speed and carry out high speed dispersion to 3000r/min, after dispersion 30min, use Hegman grind gage to test color stuffing particle diameter, record the maximum particle of color stuffing after 60 μm, reduce rotor speed to 400r/min, add saturated polyester and cenosphere, use thinner to regulate its viscosity.

Thin layer heat-reflecting heat-insulating protective system provided by the invention, its beneficial effect is, the thickness of film is thin, good heat-insulation effect, and after film reaches certain thickness, its heat insulation reflecting effect is basicly stable.T is curved, salt spray resistance, artificial weathering ageing resistance are good.
