Water-soluble temporary camouflage coating and preparation method thereof

Abstract

The invention discloses a water-soluble temporary camouflage coating and a preparation method thereof, and belongs to the technical field of camouflage coatings. A system in which water-soluble resinis compounded with acrylic emulsion serves as a base stock, multiple optical camouflage pigments and various assistants are added, mechanical dispersing, grinding and paint mixing are carried out, andthe water-soluble temporary camouflage coating is obtained. The water-soluble resin provides film forming performance for a coating, further has hydrophilic performance and swells after encounteringwater, the coating swells when the coating is cleaned by a high-pressure water gun in the later period, adhesive force is lost under high-speed currents, and disengagement happens. The adhesive performance of the film-formed acrylic emulsion is good, short-time rainwater can be resisted, balance is achieved after the water-soluble resin and the acrylic emulsion are mixed according to a certain ratio, the problems about coating adhesion in the earlier period and coating removability in the later period are solved, and the requirements of temporary coating are met. By changing the pigments in the formula, the water-soluble temporary camouflage coating can be prepared into a dark green coating, a yellow green coating, a sandy soil coating, a lime earth coating and other coatings with different colors, and can meet the requirements of camouflage coating with various geographical characteristics.

Description

technical field [0001] The invention relates to the technical field of camouflage paint, in particular to a water-soluble temporary camouflage paint and a preparation method thereof. Background technique [0002] Camouflage paint is mainly coated on the outer surface of ground military targets to reduce or reduce the characteristic difference between the target and the background in the optical, mid-far infrared or radar bands, and improve the fusion of the target and the background. According to the working band of reconnaissance and detection equipment, camouflage coatings are generally divided into three types: optical camouflage coatings, mid-far infrared camouflage coatings and radar wave absorbing coatings. [0003] The active areas of ground military targets include woodlands, deserts, grasslands, and snow fields. The camouflage coatings must consider the degree of matching and fusion of target and background features, and the compatibility of multi-band performance, ...

AI Technical Summary

Problems solved by technology

[0014] (1) Environmental protection is poor. Most temporary camouflage paints are mainly removed by organic thinners such as gasoline and paint remover, and it is difficult to recycle the cleaning waste liquid;

[0015] (2) Our army's 79-type water-based camouflage paint is produced by ball milling process. The pigment and binder are mixed together and then ball milled. Due to the large difference between pigment batches, it is difficult to control the color of the paint, and the color difference from the standard color is large; the powder fineness Large, can only be brushed and cannot be sprayed on a large area

[0016] (3) The production capacity of a single ball mill for Type 79 water-based camouflage paint is only 10kg, and the production speed is low, which is difficult to meet large-scale large-scale production; the paint is packed in plastic bags, which is prone to deliquescence, discoloration, and mildew during storage, and the storage period is short.

[0017] (4) The 79-type water-based camouflage paint has a complicated process and cannot be mass-produced, so the overall cost is high, which is not conducive to the promotion and application of paint
