Example Embodiment

[0009] The present invention will be further illustrated by specific examples below, but the present invention is not limited by the following examples.

[0010] Polychloride

[0011] Polychloride

[0012] Lead salt

[0013] Titanium Dioxide

[0014] Example 1

[0015] The production methods of the above embodiments are the same, and the specific operation steps are as follows:

[0016] First, the components of the foam layer and the co-extruded hard layer are run in the mixer at a high speed for 30-50 minutes at a certain weight percentage, and then the components of the mixed foam layer are put into the twin-screw extruder At the same time, put the mixed components of the co-extruded hard layer into the barrel of the single-screw extruder, and then move the single-screw extruder to the side of the twin-screw extruder to make the single-screw extruder. The discharge port of the screw extruder is aligned with the co-extru...

Abstract

The invention relates to an environment-friend extrusion corn foaming section bar and relative production, wherein the inner layer is foaming layer, the outer layer is extrusion rigid layer; said foaming layer contains: polyvinyl chloride resin at 63-67%; calcium carbonate at 11-15%; chlorinated polyvinyl chloride at 3-7%; and chemical agent at 12-19%; the extrusion rigid layer contains: polyvinyl chloride resin at 42-46%; calcium carbonate at 42-46%; chlorinated polyvinyl chloride at 3.5-5%; and chemical agent at 7-9%. The invention can avoid deformation and color fade, with high rigidity and lower cost, while its smoothness can reach 95%.

Description

technical field [0001] The invention discloses a green and environment-friendly co-extrusion core layer foaming profile and a production method thereof, belonging to the technical field of building profiles and the production method thereof. Background technique [0002] At present, the existing building profiles on the market are made of wood and plastic. The former is not conducive to the protection of forest resources, and is easy to be damp, moldy, and has no fireproof performance. The latter is not conducive to environmental protection and has heavy texture. , Not easy for secondary processing. Contents of the invention [0003] In order to solve the problems in the prior art, the invention provides a green and environment-friendly co-extrusion core layer foaming profile with good performance, environmental protection, non-toxicity and convenience for secondary processing and a production method thereof. [0004] In order...
