Method for reinforcing surface of foaming decoration and foaming decoration external wall prepared from same

Abstract

A method for reinforcing a surface of a foaming decoration comprises the following steps: providing a pigment, a PU protection material, a PU support material and a mold comprising at least a mold cavity; spraying the pigment on the surface of the mold cavity; according to a set certain weight ratio to enable the PU protection material to be sprayed on and completely cover one surface of the pigment; in a first set time, according to a set weight ratio to pour the PU support material into the mold cavity; and finally, standing for a second set time to fully dry the PU protection material and the PU support material, so as to prepare the foaming decoration. By employing the PU protection material, the foaming decoration has the efficacy of resisting ultraviolet irradiation, increasing surface strength, resisting flame and the like, and is improved in service life, aesthetic property and surface qualitative sense.

Description

technical field [0001] The invention belongs to the technical field of foam manufacture, and in particular relates to a method for strengthening the surface of a foam ornament and the foamed decorative exterior wall made of it, so that the finished product can resist UV, impact and flame, and greatly improve its practicality. performance. Background technique [0002] Press, foam ornaments are often used for building decoration and garden landscaping, etc. Such foam ornaments are commonly used to decorate exterior walls, heat insulation boards, decorative covers or simulated rocks, etc., to replace wood, Anti-corrosion wood, real rock, etc., which have the advantages of corrosion resistance, low maintenance rate, low deformation rate, waterproof, mildew proof, pest control and heat insulation. Moreover, the waste materials of the foam jewelry can be recycled and remanufactured 100%, which fully meets the low-carbon, environmental protection, and recyclable requirements of t...

Problems solved by technology

[0005] However, after the coating layer and / or reinforcing layer are used for a long time, after exposure to wind, rain, and hot sun, they may be peeled off from the surface of the foam, which not only greatly reduces the aesthetics, but also affects the appearance of the foam. loss of protection

Although the foam material itself does not absorb water and has the effect of waterproofing, it is a porous material and may accumulate moisture in the pores, which will eventually lead to problems such as mold, fouling or moss, so it is necessary to improve
