Embodiment 1

[0017] Embodiment 1: the preparation of PVC substrate

[0018] Raw materials (by weight, the same below): 40 parts of PVC, 75 parts of calcium carbonate, 0.5 part of internal lubricant (G60), 0.1 part of external lubricant (PE wax), 3.0 parts of calcium-zinc composite stabilizer (LY21) and CPVC 10 parts.

[0019] Among them, PVC was purchased from Anhui Huasu, calcium carbonate was purchased from Zhenjiang Xingchen, G60 was purchased from Shandong Dinghao, PE wax was purchased from BASF in Germany, LY21 was purchased from Honeywell in the United States, and CPVC was purchased from Shandong Gaoxin Plastics.

[0020] Preparation method: mix the raw materials to 120°C according to the above formula, and then discharge them into the silo when they are cold-mixed to 40°C; the materials in the silo enter the extruder to extrude and plasticize, and are formed by a mold; after three rolls, they are naturally Cool and cut the base material; attach a wear-resistant layer and a color fi...

Embodiment 2

[0021] Embodiment 2: the preparation of PVC substrate

[0022] Raw materials: 50 parts of PVC, 150 parts of calcium carbonate, 0.7 parts of internal lubricant (3316A), 0.3 parts of external lubricant (1801), 5.0 parts of calcium zinc composite stabilizer (YQ102), 20 parts of CPVC and 10 parts of ABS.

[0023] Among them, YQ102 was purchased from Honeywell in the United States, ABS was purchased from Taiwan Chimei, and the sources of other raw materials were the same as in Example 1.

[0024] Preparation method: mix the raw materials to 125°C according to the above formula, and then discharge the material to the silo after cold mixing to 45°C; the material in the silo enters the extruder to extrude and plasticize, and is formed by a mold; after three rolls, it is naturally Cool and cut the base material; attach a wear-resistant layer and a color film to the surface of the base material in turn, and press it with a hot press to obtain a hard PVC base material; the surface of the...

Embodiment 3

[0025] Embodiment 3: the preparation of PVC substrate

[0026] Raw materials: 45 parts of PVC, 90 parts of calcium carbonate, 0.6 parts of internal lubricant (G60), 0.2 parts of external lubricant (PE wax), 4.0 parts of calcium zinc composite stabilizer (CZ96), 15 parts of CPVC, 5 parts of ABS and OPE 0.2 parts.

[0027] Among them, CZ96 was purchased from Honeywell in the United States, OPE was purchased from BASF, and the sources of other raw materials were the same as in Example 1.

[0028] Preparation method: According to the above formula, mix the raw materials at high temperature to 122°C, and then discharge them into the silo when they are cold-mixed to 42°C; the materials in the silo enter the extruder to be extruded and plasticized, and are formed by a mold; after three rolls, they are naturally Cool and cut the base material; attach a wear-resistant layer and a color film to the surface of the base material in turn, and press it with a hot press to obtain a hard PVC...

Abstract

The invention discloses a PVC hard substrate and a preparation method thereof, and a PVC rigid composite board, wherein the PVC rigid substrate comprises the following raw materials in parts by weight: 40-50 parts of PVC, 75-150 parts of calcium carbonate , Balance lubricant 0.6-1.0 parts, stabilizer 3.0-5.0 parts and CPVC 10-20 parts. The PVC base material of the present invention has high hardness, and the heating dimensional change rate is very small, which can be less than or equal to 0.05%. The impact resistance and toughness of the product are greatly improved, which is convenient for subsequent processing; The composite board has higher mechanical strength and longer service life; at the same time, the PVC hard base material of the present invention is prepared by an extrusion method, which is simple and easy to implement.

Description

technical field [0001] The invention relates to a board and a preparation method thereof, in particular to a PVC base material, a preparation method thereof and a PVC composite board. Background technique [0002] Plates are widely used in household manufacturing, construction and processing industries due to their excellent characteristics such as wide sources, various types, and easy processing. According to the molding structure, the panels can be roughly divided into solid wood panels, plywood, wood-plastic panels, plywood and decorative panels. Among them, most of the existing PVC boards are added with o-benzene or p-benzene plasticizers, the texture is soft, the heating dimensional change rate is high (up to 0.167%), and the impact resistance and toughness of the product are poor, which is not conducive to subsequent processing. [0003] Therefore, urgently need to solve above-mentioned technical problem. Contents of the invention [0004] Purpose of the invention:...
