Problems solved by technology

[0003] PVC foam board is light and strong, and it is also the most commonly used material in building materials. However, most of the ceilings in the prior art are hollow and dense structures without foaming. Due to visual fatigue and other reasons, it is impossible to enter the high-end market of building materials. At the same time, it is often caused by problems such as sagging deformation when exposed to heat, cracking and yellowing, a large amount of black smoke or even burning after encountering fire, which leads to its short service life and seriously affects its products.

The PVC foamed ceiling prepared by the invention has the advantages of heat resistance, no droop, matte property, smoke suppression, flame retardance, environment friendliness, light weight, thinness, safety, long action, long service life, wide application range and the like, so that the material can be applied to building ceilings of residences, offices, exhibition halls, meeting places and the like,various decorations and the like; the invention further provides a preparation method of the material, wherein the preparation method is low in cost, high in cost performance, scientific, reasonable,simple and easy to operate.

Description

technical field [0001] The invention belongs to the technical field of polyvinyl chloride ceiling, and in particular relates to a PVC ceiling and a preparation method thereof. Background technique [0002] The ceiling is a kind of ceiling decoration material, which has the functions of heat preservation, heat insulation, sound insulation, and sound absorption. It is also a hidden layer for electrical, ventilation and air conditioning, communication and fire protection, and alarm pipeline equipment. At present, the commonly used ceilings include mineral wool boards, silicon-calcium boards, aluminum gusset boards and PVC boards. [0003] PVC foam board is light and strong, and it is also the most commonly used material in building materials. However, most of the ceilings in the prior art are hollow and dense structures without foaming. Due to visual fatigue and other reasons, it is impossible to enter the high-end market of building materials. At the same time, it is often ca...
