Plant fiber environmental protection material and its manufacturing method and application

Abstract

The invention discloses a plant fiber environment-friendly material and a preparation method thereof as well as application of the material in tableware, toys, furniture, decoration or wall. The preparation method comprises the following steps of: pretreating, grinding and screening the plant fiber; mixing the screened plant fiber powder with an adhesive and a modification aid, and stirring at high temperature, wherein the adhesive mainly adopts hydroxypropyl methyl cellulose; filtering with a riddler, and dehydrating and preheating the screened organic synthesis plant fiber raw material; and performing high-temperature die pressing. According to the plant fiber environment-friendly material as well as the preparation method and application thereof, the product has good performance and additional functionality, can be applied to wider fields, conforms to relatively high requirements on using safety, and facilitates environmental protection so as to overcome the shortcomings of the existing plant fiber environment-friendly material and a preparation method and application thereof.

Description

technical field [0001] The invention relates to the field of environment-friendly materials and their manufacture, in particular to a plant fiber environment-friendly material and its manufacturing method and application. Background technique [0002] So far, the materials commonly used in people's lives include: plastics derived from petroleum extracts; ceramic materials fired from clay; wood and bamboo materials obtained by cutting wood and bamboo plants; chemical raw material mixture melamine; and various metal materials. The raw materials of the above-mentioned materials are all taken from non-renewable resources. Since the 21st century, the protection of the environment and the rational and efficient development and utilization of resources have become the focus of the world's attention. How to develop new environmental protection materials, which can effectively reduce the waste of resources without affecting people's life and health, has become a global topic. . ...

Problems solved by technology

[0007] In addition, plant fiber is a natural linear polymer, and the cellulose in it belongs to the structure where the crystalline region and the non-crystalline region coexist. Due to the structure and the influence of intramolecular and intermolecular hydrogen bonds, cellulose is difficult to dissolve in common solvents. Therefore, the plant fiber has a strong polarity, which makes its dispersion in the resin matrix extremely poor, and it is difficult to achieve uniform dispersion.

In addition, the matrix resin is usually a non-polar and non-hydrophilic material. The compatibility between the plant fiber and the resin matrix is ​​poor, and the interface bonding strength is low. It is necessary to fully tap the value of the plant fiber and carry out in-depth processing Utilization, pretreatment and modification of plant fiber is the key to limit the use of plant fiber, otherwise the mechanical properties, water resistance and durability of its products will be affected

[0008] This shows that the above-mentioned existing plant fiber environmental protection materials obviously still have inconvenience and defects in products, manufacturing methods and use, and need to be further improved urgently.
