Embodiment 1

[0031] Embodiment 1: a kind of production method of PET thermoplastic fiber non-burning brick supporting board, carry out according to the following steps:

[0032] (1), raw material crushing:

[0033] Raw materials: polyester staple fiber, polyethylene and glass fiber. The raw materials are crushed into flakes by a high-speed pulverizer to form flakes. After pulverization, the mesh size of the raw materials is 50 mm, and the speed of the high-speed pulverizer is 280 rpm;

[0034] (2), heating and drying:

[0035] Put the sheets into the drying room in batches for drying. The temperature of the drying room is 45°C and the time is 1 hour. During the drying process, the sheets are turned over from time to time;

[0036] (3), fully stir:

[0037] Put the dried flakes into the blender for stirring, add calcium carbonate and black masterbatch during the stirring process, and stir until uniform;

[0038] (4), extrusion preheating:

[0039] Put the uniformly stirred flakes into t...

Abstract

The invention relates to a supporting plate, in particular to a production method of a PET (Polyethylene Glycol Terephthalate) thermoplastic fiber baking-free brick supporting plate. The production method comprises the following steps: raw material crushing, heating and drying, sufficient mixing, extruding and preheating, tray preassembling, melting and heating, folding, molding in a hydraulic mold, trimming deflashing, cooling and sizing, and wearing layer spraying. The PET thermoplastic fiber baking-free brick supporting plate produced by the production method is good in quality, good in crushing resistance, and outstanding in surfacing performance.

Description

technical field [0001] The invention relates to a supporting board, in particular to a production method of a PET thermoplastic fiber non-burning brick supporting board. Background technique [0002] Supporting boards in the prior art mainly include bamboo plywood, wood plywood, PVC plastic board and foamed PVC plastic board, because bamboo plywood and wood plywood are easy to absorb water, expand and easily delaminate and crack, which affects the quality of unburned bricks; Boards and foamed PVC plastic boards have a high density, and at the same time are relatively heavy, and are easily deformed and brittle. Contents of the invention [0003] The present invention mainly solves the deficiencies in the prior art, and provides a kind of non-burning PET thermoplastic fiber brick that can solve the shortcomings of the existing pallet, has excellent compression resistance, long service life, and can withstand more harsh use environments. The method of production of pallets. ...
