除甲醛室内装饰膜
摘要：
本发明涉及一种除甲醛室内装饰膜，所述装饰膜由下述重量份的原料制备而得：聚氯乙烯树脂粉100份、增塑剂40～60份、钙锌稳定剂1～5份、甲醛吸收剂2～8份、色料1～4份、钛白粉5～11份、耐寒剂2～8份。本发明通过优选环保原料和改进生产工艺，使其具备常规装饰膜所不具备的甲醛吸收功能，具有除室内甲醛污染的功效；另外，其拉伸强度、撕裂强度，各项指标均符合国家标准；本发明克服了甲醛吸收剂高温不稳定的缺点，通过控制压延温度、添加钙锌稳定剂等手段，降低产品加工难度。本发明具有环保性好、稳定性高、甲醛吸收性好等优点。
摘要（英）：

The invention relates to a formaldehyde-removal indoor decorative film which is prepared from the following raw materials in parts by weight: 100 parts of polyvinyl chloride resin powder, 40-60 parts of plasticizer, 1-5 parts of calcium-zinc stabilizer, 2-8 parts of formaldehyde absorbent, 1-4 parts of pigment, 5-11 parts of titanium white and 2-8 parts of anti-freezing agent. By selecting the environment-friendly raw materials and improving the production technique, the formaldehyde-removal indoor decorative film has the formaldehyde absorption function which is not possessed by the conventional decorative film, and has the effect of removing indoor formaldehyde pollution. Besides, the tensile strength, tear strength and various indexes of the formaldehyde-removal indoor decorative film satisfy the Chinese standard. The formaldehyde-removal indoor decorative film overcomes the defect of low high-temperature stability in the formaldehyde absorbent; and calendering temperature control, calcium zinc stabilizer addition and other means are adopted to lower the processing difficulty of the product. The formaldehyde-removal indoor decorative film has the advantages of favorable environment friendliness, high stability, favorable formaldehyde absorptivity and the like.
