Wet paper molding method and paper plastic finished product

Abstract

The invention provides a wet paper molding method and a paper plastic finished product, which are used for molding the paper slurry into a dried paper plastic finished good. The method comprises steps of a slurry taking step, a pre-pressing step, a second pre-pressing step, a thermal-pressing step, a thermal pressing molding step and a cutting step; the paper slutty is taken from the slurry tank of the mold to form a wet green by the first lower mold; the first lower mold and the first upper mold perform press fitting to perform the first pre-pressing step; the second upper mold and the second lower mold perform press fitting to perform second pre-pressing step; the third upper mold and the third lower mold perform hot press molding. The invention increases the drying degree of the wet green, and shortens the time spent on drying and molding of the paper plastic finished good. The paper plastic finished good are smooth on the inner surface and the outer surface, and the inner surface and the outer surface have the surface smoothness degree value which is greater or equal to 3Bekk second.

Description

technical field [0001] The invention relates to a wet paper molding technology, in particular to a wet paper molding method for accelerating the drying and molding efficiency of a wet paper embryo body to shorten the wet paper molding process time and its paper molding product. Background technique [0002] Pulp molded products (or paper-plastic products) are made of pulp fibers as the main raw material, and are obtained by hot-pressing pulp fibers with molding dies. It can be divided into two technologies: dry paper molding and wet paper molding. Paper-plastic products can be made into packaging containers for commodities or packaging materials or isolation materials for isolating commodities inside packaging containers, gradually replacing sponges or foams that are traditionally used for protection and shockproof on inner or outer packaging of products. Therefore, the packaging containers and interlayer materials used by electronic products on the market are gradually repl...

Problems solved by technology

[0006] In order to solve the problem that the hot pressing step in the existing wet paper plastic molding process is too time-consuming and lengthens the overall process time so that the mass production speed is too slow and the production yield is too low, a main purpose of the present invention is to provide a wet paper plastic Forming method for automatically forming a pulp material body into a dried paper-plastic product
