Spun-bonded polypropylene board and manufacturing method thereof

Abstract

A spun-bonded polypropylene board comprises PP plastic boards and a chemical fiber grid layer and is structurally characterized in that the chemical fiber grid layer is of a net-shaped fiber structure, the PP plastic boards comprise two layers, the chemical fiber grid layer is located between the two layers of PP plastic boards, and the chemical fiber grid layer is in hot fusion connection with the PP plastic boards. The spun-bonded polypropylene board has the beneficial effects that the impact-resisting degree is high, and the board is not prone to being damaged. A manufacturing method of the spun-bonded polypropylene board is characterized by comprising following steps: a, an extrusion device A is arranged in the direction of a whole main device, and in the extrusion device A, polypropylene particles, polypropylene particle raw materials, modified materials and auxiliary materials are sufficiently mixed to form a formula raw material to be poured into a stirring structure to be stirred; and the beneficial effects of being high in rate of finished products and high in assembly line production degree are achieved.

Description

technical field [0001] The invention relates to a board and a manufacturing method thereof, in particular to a spun-bonded polypropylene board and a manufacturing method thereof. It belongs to the technical field of synthetic boards. Background technique [0002] In the prior art, due to the weak ductility and rigidity of the material itself, the physical properties of ordinary plastic plates are easy to break, poor impact resistance, weak tensile strength, and low burst resistance. Furthermore, after long-term use, the flatness of ordinary plastic sheets is easily affected, and the surface of plastic sheets is prone to swelling, waves, and warping. On the one hand, it affects the appearance, and on the other hand, it affects its performance, especially in the use of furniture. cause trouble in use. Ordinary plastic plates have a low service life, and will generally oxidize and deform in about three years, requiring regular replacement and high economic costs. Ordinary pl...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problems that ordinary plastic plates in the prior art are easily broken, have poor impact strength, weak tensile strength, and low burst resistance; provide a spunbonded polypropylene plate and its manufacturing method, The polypropylene board has a three-layer structure, and the chemical fiber grid layer is located between two layers of PP plastic boards. The three-layer structure is thermally fused and connected to each other, which is not easy to break, has strong impact strength, strong tensile strength, and high burst resistance; The manufacturing method of the polypropylene board passes through the stages of hot melting and bonding, and then heat-presses the roller to form a spun-bonded polypropylene board, which has the characteristics of simple manufacturing and convenient assembly line production
