Coated polyurea material and coated polyurea material plate and preparation method

Abstract

The invention belongs to the technical field of building materials and discloses a coated polyurea material and a coated polyurea material plate and a preparation method. The coated polyurea materialconsists of components of a polyurea coating and a polyether material, wherein the mass ratio of the polyurea coating to the polyether material is 1:1. The preparation method of the coated polyurea material comprises the following steps: heating the polyurea coating and the polyether material to 60 DEG C, and carrying out high-temperature high-pressure coating molding by using special polyurea equipment; placing a foamed sculptured plastic bottom plate on a coated polyurea material plate, and coating the foamed sculptured plastic bottom plate by a waterproof polyurea coating layer, a repairinglayer, a modified polyurea coating, a colored drawing layer and an anti-ultraviolet vanish layer from top to bottom in sequence. By adopting the coated polyurea material, the shapes of EPS (ExpandedPolystyrene), EVA (Ethylene Vinyl Acetate) and a soft body are not easily damaged, ultraviolet rays can be prevented when the coated polyurea material is used outdoor, the structure of a product can be changed, the service life of the product can be prolonged, and the attractiveness of the product can be improved.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a sprayed polyurea material, a sprayed polyurea material board and a preparation method. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] The domestic related technology is foam sculpture substrate-water-based putty repair-polishing-color paint-overall varnish. [0004] The existing defects are: the elastic modulus is low, and the rigidity is often felt insufficient in the product structure, and it is easy to deform. The long-term temperature resistance is poor, and it cannot be used at high temperature for a long time, and the strength will decrease obviously when the temperature is above 40°C; [0005] Aging phenomenon: It is easy to cause performance degradation under the action of ultraviolet rays, wind, sand, rain and snow, chemical media, mechanical stress, etc. Cracks easily...

AI Technical Summary

Problems solved by technology

[0007] (1) FRP products in the prior art are used outdoors for about one year, and the surface will have defects such as cracking, powdering, and discoloration

[0008] (2) Existing coatings have slow curing and low production efficiency

Can't save a lot of money

Poor toughness, poor low temperature impact resistance, can not withstand cycle heat
