One is coated with section bar entirely, effectively solves existing section bar relatively costly, the problems such as the quality of production is bad, and production efficiency is low；Its technical scheme solved is that the present invention includes sandwich layer and top layer, it is characterised in that, core material consists of: PVC:25kg, reclaimed materials powder: 100kg, CPE:6kg, rutile titanium white lead: 2kg, ACR:0.5kg, PE wax: 0.1kg, calcium zinc stabilizer: 2.5kg, fire retardant: 6kg, brightening agent: 10g, ultramarine: 3g；Skin-material consists of: PVC:100kg, nanometer calcium: 12.5kg, CPE:12.5kg, rutile titanium white lead: 4.5kg, ACR:1.5kg, stearic acid: 0.1kg, PE wax: 0.1kg, calcium zinc stabilizer: 5kg, antioxidant: 0.5kg, fire retardant: 5.5kg, brightening agent: 30g, ultramarine: 8g；The present invention uses the formula that sandwich layer is different with top layer, both ensure that the property needed for top layer, and had reduced again the cost requirement of sandwich layer, it is achieved that reduces cost and ensures the unification of quality, and can reduce certain wasting of resources by reclaiming old material. |
