Production process of super strong glass fiber plastic tray

Abstract

The present invention discloses production process of super strong GRP tray, and the super strong GRP tray is made with super strong GRP rod and super strong GRP plate and through ultrasonic, heating or pressurized welding. The super strong GRP tray may be made with only super strong GRP plate and the corresponding production process includes the steps of cutting material, forming, combining, welding or adhering. Or, super strong GRP tray may be made with super strong GRP plate and super strong GRP to form skeleton, and the corresponding production process includes the steps of cutting material, forming plate, locating the facing sheet, pressurizing the rods, welding, etc. The super strong GRP tray product has the advantages of high mechanical performance, powerful bearing capacity and low cost.

Description

technical field [0001] The invention relates to a production process of a super-strong glass fiber plastic tray. Its products have the characteristics of super strong mechanical properties and bearing capacity, and low processing cost. Its cost performance is much better than conventional plastic pallets, and can be widely used in construction, transportation and civil life and other fields. Background technique [0002] Among the five general-purpose plastics of polymers, polypropylene (PP) is the fastest-growing variety. PP modification, like PE, can be divided into two methods: chemical modification and physical modification. Chemical modification is mainly copolymerization, grafting, crosslinking, etc., and the purpose of modification is achieved by changing the molecular structure of polypropylene (PP). Physical modification is mainly to add additives such as blending, reinforcement, filling, etc. to endow polypropylene (PP) with new properties. The purpose of modify...
