Problems solved by technology

[0004] However, every electric pole, light pole, or guardrail painted with paint will be damaged by wind, rain and ultraviolet rays in the sun. After a period of time (about 6 months) after painting, the paint will disappear Gradually disappear, so that the poles; light poles or guardrails no longer have the function of warning safety

Abstract

A technology for preparing the safety warning material by multi-color extruding out features that the polyvinyl chloride (PVC), polyethylen (PE), refractory cross-linked polyethylene (PE), or polypropylene (PP), which can have different colors, are used as raw materials, and includes co-extruding out, shaping by co-extruding die, splitting, cooling, drawing and winding. Said co-extruding die is composed of external, central and internal dies and said central die can be turned to make a skewing between different colors, so improving its warning action.

Description

[0001] Technical field [0002] The present invention relates to a manufacturing method and mold for different-color co-extrusion safety equipment, especially a new manufacturing method and mold that can make two different-color materials through co-extrusion to make extremely conspicuous and warning color safety equipment, providing application Warning and buffering safety equipment for utility poles; light poles; guardrails, etc. Background technique [0003] At present, electric poles on both sides of the road; light poles or guardrails, etc., in order to provide a considerable reflective safety effect in the case of poor environmental vision, all will be painted with black / yellow cross paint on the electric poles; light poles; or guardrails, The function and purpose of this paint is to provide a safer warning effect to pedestrians and vehicle drivers on the road. [0004] However, every electric pole, light pole, or guardrail painted with paint will be damaged by wind, ra...
