Problems solved by technology

However, oil-based coatings have inherent defects, such as dangerous storage, non-volatile, and harmful to the environment and human body. Water-based coatings are gradually being developed, but aluminum powder coatings are different from other existing water-based coatings, and their application fields require different properties to meet It is required for film projection, but after the existing aluminum powder water-based screen coating dries, the aluminum powder on the coating is easy to be touched off, and blackening occurs. When dust is occupied, it cannot be cleaned with water or other detergents, and the floating aluminum Powder is the easiest to oxidize, and the polarization contrast is easily weakened, which greatly reduces the use time of the screen

Embodiment

[0021] The preparation method of PVC composite material based on self-drying water-based aluminum powder coating is as follows: adding water-based additives into water, adding water-based aluminum powder after stirring, adding water-based resin under stirring, and stirring to obtain self-drying water-based aluminum powder coating; The self-drying water-based aluminum powder coating is routinely coated on the surface of the PVC material to obtain a PVC composite material based on the self-drying water-based aluminum powder coating; after conventional natural drying or heating drying, a screen is obtained. Specifically, the above-mentioned water-based leveling agent, water-based anti-settling agent, and water-based wax slurry were added to water at a stirring rate of 1000 rpm, stirred for 15 minutes, and then added with a water-based defoamer and water-based dispersant, and stirred at a stirring speed of 1200 rpm for 5 minutes, Then add water-based aluminum powder, stir at 800 rp...

Abstract

The invention discloses a PVC composite material based on a self-drying water-based aluminum powder coating as well as a preparation method and application thereof. The PVC composite material comprises a PVC material and the self-drying water-based aluminum powder coating, and the coating comprises the following components in percentage by mass: 50-60% of water-based resin, 20-25% of water-based aluminum powder and 5-15% of a water-based additive. The water-based coating is used for replacing oil-based coating, water is used as a solvent, the cost is reduced, safety and environmental protection are achieved, and environmental protection and physical health of constructors are greatly reduced; and a dry film has good transparency, water resistance, weather resistance and yellowing resistance, the coating can be cleaned with water or a cleaning agent after being used for a long time, the corrosion of water to the dry film is avoided, and the influence of humidity in air on the weather resistance and yellowing resistance of the dry film is also avoided.

Description

technical field [0001] The invention belongs to composite material technology, and particularly relates to a PVC composite material based on self-drying water-based aluminum powder coating, a preparation method and application thereof. Background technique [0002] PVC material is currently widely used in cinemas showing 3D movie effects. Its initial form is soft white PVC with holes. The surface is sprayed with a silver coating to protect the PVC substrate and enhance the 3D effect. The coating must have 3 An important performance index: gain brightness, scattering angle, polarization contrast; the gain brightness is the ratio of the screen reflection brightness in the 5° angle direction under the same lighting strip to the brightness of the ideal diffuse screen under the same conditions, which is reflected in the viewing angle. The degree of visual stimulation to the eyes during filming, according to national standards and industry standards, the general gain brightness is...
