Abstract

The invention provides a shading material and a production process thereof. By the shading material, the technical problems that existing shading composite materials have simple components and low practicability and do not have flame and ultraviolet resistance characteristics, no production process is provided and the like are solved. The shading material comprises a base cloth layer. PVC (polyvinyl chloride) film layers are arranged on the upper side and the lower side of the base cloth layer respectively. Each PVC film layer comprises, by weight, 55-75 parts of PVC resin, 24-36 parts of plasticizers, 0.5-1 part of lubricant, 3-5 parts of stabilizers, 3-4 parts of shading powder, 1-3 parts of liquid fire retardants and 0.6-1.2 parts of ultraviolet absorbents. The shading material and the production process thereof have the advantage of high practicability.

Description

technical field [0001] The invention relates to a light-shielding material, in particular to a light-shielding material and a manufacturing process thereof. Background technique [0002] At present, the mainstream thinking in the world is environmental protection, energy saving and safety. In the construction industry, the manufacture and application of windows in today's buildings will bring a lot of energy consumption and light pollution. [0003] After searching, for example, Chinese patent literature discloses a light-shielding composite material [application number: 201410145818.2; publication number: CN 104972716A]. This light-shielding composite material is characterized in that it includes a first transparent film layer, a first vacuum aluminized layer, a composite adhesive layer, a second transparent film layer, a polyethylene coating composite layer and A non-woven fabric layer; the thickness of the first vacuum aluminized layer is 400-700 angstroms. [0004] Al...
