Embodiment Construction

[0013] like figure 1 The nano-calcium-plastic fiber felt composite automotive interior lining board shown is composed of four layers of materials. The surface layer is nano-calcium plastic 1, the second layer is thermoplastic fiber felt 2, the third layer is nano-calcium plastic 3, and the bottom layer is Non-woven fabric4. The nano-calcium plastic on the surface layer and the nano-calcium-plastic component on the third layer, in parts by weight, are: 100 parts of waste plastics, 5-30 parts of nano-calcium carbonate, an appropriate amount of plastic modifiers, stabilizers and flame retardants; The components of the thermoplastic fiber mat are, by weight percentage: 55-70% of hemp fiber or brown fiber or glass fiber or polyester fiber, 30-45% of polypropylene fiber or polyethylene fiber. The calcium plastic content per unit area of ​​nano-calcium-plastic layers 1 and 3 is 300-500g / m 2 , the mass per unit area of ​​thermoplastic fiber mat 2 is 500-800g / m 2 , the weight per un...

Abstract

A composite lining sheet for the internal decoration of car is composed of surficial nano-Ca/plasticl ayer, thermoplastic fibre felt, nano-Ca/plastic layer and non-woven cloth as substrate. It is prepared through proportionally mixing the waste plastics with nano-calcium carbonate, plastic modifier and stabilizer to obtain the nono-Ca/plastic powder, thermal fusing, applying it to the thermoplastic fibre felt, cold rolling, and attaching non-woven cloth to its one surface.

Description

technical field [0001] The invention relates to a nano-calcium-plastic fiber felt composite automobile interior lining board and a manufacturing method thereof. Background technique [0002] A large number of various plastics are used in various fields of the national economy and people's daily life, so there is a large amount of waste plastics, and the proportion of waste plastics in urban waste is almost 20%. Due to the degradation and aging of waste plastics in long-term use, its strength is greatly reduced, and its application range is limited. If a new process is adopted, the cost is not higher than that of waste plastics, or even lower. The strength is greatly improved, so that it can be applied to products with high technical requirements, which undoubtedly has great economic significance. [0003] In addition, as far as automotive interior linings are concerned, polymer material foam boards and various fiberboards are mostly used at home and abroad. These materials ...
