Abstract
The invention relates to a ceiling sheet, in particular to an environmental-friendly lead-free PVC ceiling sheet and a manufacturing method and applications thereof. The environmental-friendly lead-free PVC ceiling sheet is obtained by blending the following components according to parts by weight and then extruding to mould: 50-100 parts of PVC resin SG-5, 15-50 parts of nano calciumcarbonate, 3-10 parts of calciumzinc stabilizer, 1-3 parts of rutiletitanium dioxide, 1-3 parts of CPE impact modifier, 1.5-5 parts of ACR enhancer, 0.2-0.8 part of stearic acid, 0.3-1.0 part of calciumstearate, and 0.2-0.4 part of PE wax. The PVC ceiling sheet is used as a novel environmental-friendly lead-free material of which the lead content is less than or equal to 200PPM, and is applicable to non-toxic places with high environmental requirements such as hospitals, operating rooms, baby rooms, food plants, and the like. The invention also discloses the manufacturing method of the ceiling sheet and ceiling gusset plates manufactured by the sheet.
Description
technical field [0001] The invention relates to a ceiling board, in particular to an environment-friendly lead-free PVC ceiling board and its manufacturing method and application. Background technique [0002] At present, thousands of PVC ceiling manufacturers in China use composite lead stabilizers as stabilizers when producing PVC gussets. Lead stabilizers (including basic lead salts and metal soaps) are cheap and have good stabilizing effects. traditional stabilizer. Such stabilizers mainly include: tribasic lead sulfate, dibasic lead phosphite, dibasic lead stearate, lead stearate, calcium stearate, zinc stearate, etc. The process has good stability, small color difference and simple process in the production process, but the finished product contains lead which is harmful to human body. At present, the lead content of most PVC gussets on the market is generally above 5000ppm, which is harmful to the human body. Today, people are increasingly strict with environmental ...
