Problems solved by technology

[0003] Due to the high barrier requirements of the STP sheet itself, the packaging film itself is thick, the production process is difficult, and the surface flatness is not high, wrinkles and other phenomena are prone to occur.
If the surface is uneven and wrinkled, it will not only affect the appearance of the packaged STP board, but also affect the heat insulation and thermal insulation effect of the finished STP building exterior wall board

Abstract

The invention discloses a protective film for an STP building exterior wall thermal-insulation fire-retardant material. The protective film comprises an aluminum-coated glass-fiber gridding cloth layer, an aluminum layer, a polyester (PET) layer, a two-way stretch nylon layer, an aluminum layer, a two-way stretch nylon layer and a compound polyethylene layer which are respectively arranged from outside to inside. Compared with the prior art, the protective film for the STP building exterior wall thermal-insulation fire-retardant material comprises the following characteristics that a flexible packaging material is good in smoothness effect and excellent in barrier effect and ageing resistance. The protective film disclosed by the invention is packaged outside a panel, and thus, not only is a protection function performed but also the barrier effect is performed on cement and adhesives, and the barrier effect is performed on temperature and noise.

Description

technical field [0001] The invention belongs to a flame-retardant material protective film, in particular to an STP building exterior wall thermal insulation flame-retardant material protective film. Background technique [0002] STP board is an emerging fire-retardant material for external wall insulation in the construction industry. The material has excellent thermal insulation effect, the thermal conductivity is lower than 0.008w / (m·K), and the thickness is only 1 cm. This is a major breakthrough in the thermal insulation industry. In the past, EPS boards were usually used, with a thickness of about 6 cm to 8 cm, and the existing conventional thermal insulation materials can be burned. The thickness of the STP board is only one-eighth of that of ordinary thermal insulation materials, and the thermal insulation and flame retardant effect is better. The unit weight of the product is light, and the weight per square meter after being placed on the wall is about 12 kilogra...
