Problems solved by technology

At present, the processing technology adopted by the light storage type self-luminous profiles on the market generally sprays, pastes or calenders the light storage type self-luminous materials on the surface of the profiles, or inlays them in the middle of the profiles. Although the light storage type self-luminous profiles produced by these processing methods have light storage However, due to the poor adhesion between the profile and the luminescent material, the poor stability of the profile, etc., the luminous layer is easy to peel off and fall off and cannot maintain its luminous efficacy for a long time.

Abstract

The coextruded light storage type luminous irregular PVC / PVC or PMMA / PVC plastic profile is produced through co-extrusion of base resin material and luminous resin material. The production process includes extruding PVC base material in the main extruder, extruding the light storage type luminous PVC or PMMA material in the auxiliary extruder, adhering of the extruded base material and luminous PVC or PMMA material, forming, cooling and settling. The profile is used in making door, window, fencing in building, can emit light continuously after absorbing visible light, and has beautifying and indication function.

Description

technical field [0001] The invention relates to the field of plastic profiles for making doors, windows, fences, etc., in particular to the co-extrusion method to make plastic profiles with luminescent properties and its production technology. Background technique [0002] The successful development of light-storage self-luminous materials has opened up many new application paths for polymer materials. The light-storage self-luminous materials are used as a functional filler and added to the plastic profile formula in a certain proportion. Through extrusion, injection molding, Calendering, coating and molding to prepare plastic products with light storage type self-luminous function. Such as various luminous films and boards (ZL96238019, ZL00268636); various signs, warnings, escape route signs, etc. (ZL01233873, ZL03201954); plastic masterbatches (ZL99127572, application number 02123551); ZL 200420150086) and so on. Most of the plastics used are commonly used varieties suc...
