Problems solved by technology

On the one hand, kaolin has a large output and low price, and its compounding with polymer matrix can greatly reduce the cost of plastics. On the other hand, the addition of kaolin can improve the thermal stability, hardness, rigidity and endow the material with certain properties. However, the raw ore kaolin directly mined at present has small particle size, high surface energy, and is easy to agglomerate. The surface contains hydrophilic hydroxyl groups and oxygen-containing groups, which are very different from the interface of polymer materials. dispersion

Embodiment Construction

[0014] A pvc plastic wood board and a preparation method thereof, prepared from the following raw materials in parts by weight (kg): polyvinyl chloride 100, kaolin 15, wood powder 30, carbonyl iron powder 5, copper sulfate pentahydrate 0.8, nitrile rubber 4. Titanate coupling agent NDZ2010.2, silane coupling agent YH620.4, petrolatum 4, octyl zinc maleate 3, light calcium carbonate 6, ceramic powder 4;

[0015] The pvc plastic wood board and its preparation method are prepared by the following specific steps:

[0016] (1) Prepare the titanate coupling agent NDZ201 and 90% isopropanol solution at a ratio of 1:2 to form a coupling agent solution, add it dropwise to high-speed stirring kaolin several times, stir it evenly, and dry it in vacuum at 100°C for 3 hours And put it at room temperature for 24 hours for later use;

[0017] (2) finely grind copper sulfate pentahydrate through a 100-mesh sieve on a ball mill for subsequent use, then thinly pass the nitrile rubber for 3 tim...

Abstract

The invention discloses a PVC (polyvinyl chloride) plastic wood board and a preparation method thereof. The PVC plastic wood board is prepared from the following raw materials in part by weight: 100-105 parts of polyvinyl chloride, 15-18 parts of kaolin, 30-35 parts of wood powder, 5-7 parts of iron carbonyl powder, 0.8-1.2 parts of copper sulfate pentahydrate, 4-6 parts of nitrile rubber, 0.2-0.4 part of titanate coupling agents NDZ201, 0.4-0.6 part of silane coupling agents YH62, 4-5 parts of vaseline, 3-4 parts of octyl zinc maleate, 6-7 parts of light calcium carbonate and 4-5 parts of ceramic powder. The prepared PVC plastic wood board is high in impact resistance and high in size stability, is wear-resistant, chemical-corrosion-resistant and moth-proof, has dual machinability of wood and plastics, and is high in practicability and worthy of being popularized.

Description

technical field [0001] The invention relates to the technical field of wood-plastic composite materials, in particular to a PVC plastic-wood board and a preparation method thereof. Background technique [0002] As early as the 1940s, it was discovered that nitrile rubber and PVC were used together for research. Nitrile rubber has a certain polarity, and the solubility parameters of PVC are very close. They are both amorphous polymers. Good compatibility, so they are usually blended, and the alloy material obtained has excellent weather resistance, solvent resistance, good mechanical strength and processing performance, and is widely used in seals, wire and cable sheathing, Oil pipeline and other fields. The alloy materials of nitrile rubber and polyvinyl chloride are divided into cross-linked type and non-cross-linked type. The cross-linked alloy is insoluble and infusible, which is difficult to recycle and causes serious pollution to the environment. Although the non-cross...
