Abstract

The invention belongs to the field of plant fiber material, and provides a degradable reinforced plant fiber material and a preparation method thereof. The degradable reinforced plant fiber material comprises 50 to 52% of rice husk powder, 14% of a degradable adhesive, 12.5 to 13% of a reinforcing agent, 1 to 3% of a release agent and 18 to 20% of water. The degradable adhesive comprised 10% of polyvinyl alcohol and 4% of urea-formaldehyde resin; the reinforcing agent comprises 12% of heavy calcium carbonate and 0.5 to 1% of nano silicon dioxide, and the release agent is stearic acid or zine stearate. The degradable reinforced plant fiber material helps to solve problems of existing plant fiber material that: the existing plant fiber material is non-degradable, production cost is relatively high, strength is insufficient, and production period is long. The degradable reinforced plant fiber material is degradable, and possesses high mechanical strength and toughness, and is capable of widening applications of plant fiber material.

Description

technical field [0001] The invention relates to the field of plant fiber materials, in particular to a degradable reinforced plant fiber material and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, the demand for natural resources is also increasing, exacerbating the shortage of various resources, and the cost is also rising. In life, plastic products, wood-plastic products and paper products are widely used. However, due to the shortage of petroleum resources and the fact that they are not easy to degrade, the development of plastic products is limited. Wood-plastic products and paper products need to cut down trees, which not only damages the natural resources of the ecological environment, but also produces a large amount of sewage in papermaking, which brings great harm to the environment. Here comes secondary pollution. Furthermore, although wood-plastic products have high mechanical strength, they are dif...
