Wood-plastic material prepared from papermaking waste and preparation method thereof

Abstract

The invention discloses a wood-plastic material prepared from papermaking waste. The wood-plastic material comprises the following components in percentages by mass: 30% to 35% of papermaking waste, 30% to 40% of wood flour, 15% to 20% of ceramic powder, 1% to 5% of sorbitol, 1% to 3% of a silane coupling agent, 3% to 6% of maleic anhydride grafted polyethylene, 1% to 2% of aluminum chloride, 3% to 5% of poly ethylene glycol monomethyl ether and 1% to 2% of blocking isocyanate. Firstly, the silane coupling agent, maleic anhydride grafted polyethylene and aluminum chloride are added and mixed,the aluminum chloride is beneficial for uniform mixing of the raw materials, and in combination with the adding sequence of the raw materials, the modification effect of each accessory ingredient on plastic, wood flour and ceramic powder can be strengthened; the sorbitol is further added as an activation modifier, and is matched with the blocking isocyanate and poly ethylene glycol monomethyl ether, so that modification on the wood four and ceramic powder can be realized sufficiently, the interfacial compatibility among the wood flour, ceramic powder and plastic is improved, and the performance of the wood-plastic material is strengthened.

Description

technical field [0001] The invention belongs to the technical field of wood-plastic materials, and in particular relates to a wood-plastic material prepared from papermaking waste and a preparation method thereof. Background technique [0002] The paper industry is an important basic raw material industry that is closely related to the development of the national economy and social undertakings. The consumption level of paper and cardboard is a symbol of a country's modernization level and civilization. my country has become a major country in the production, consumption and trade of the world's paper industry. In addition to the large amount of wastewater generated during the papermaking process, there is also a large amount of solid waste generated. With the gradual expansion of the industrial scale, the environmental impact of these solid wastes has become increasingly prominent, and various ecological and social problems have also gradually emerged. The traditional trea...

Problems solved by technology

However, due to the large polarity difference between the wood powder and the plastic, the two have poor dispersion and surface adhesion. Therefore, it is necessary to modify the wood powder to improve the interfacial phase between the wood powder and the plastic matrix. capacity

However, the currently commonly used modifiers and coupling agents are not effective in modifying wood powder, and side reactions are prone to occur under high temperature conditions, which affect the performance of wood-plastic materials.

Moreover, the impact resistance and wear resistance of the current wood-plastic materials are poor, especially when used for outdoor park decoration, because they will often be impacted and rubbed during use, their impact resistance and wear resistance must be improved
