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...

Examples

Embodiment

[0057] The foam sculpture itself is a fragile and fragile structure, which is attached to the base of the foam sculpture through an external coating structure to achieve the protection of the outer surface of impact resistance, wear resistance, rain resistance and weather resistance. No cracking, no delamination, impact resistance, aging resistance, UV resistance and other functions after being impacted by external forces.
