Abstract

PURPOSE: Nano cellulose fiber-reinforced plastic is provided to enable various applications due to inexpensive costs, light weight, excellent strength, and no harmfulness. CONSTITUTION: Nano cellulose fiber-reinforced plastic is prepared by the steps of: obtaining nano cellulose extracted from plants and timbers in a high pressure extractor in several times; compressing the nano cellulose to obtain a nano cellulose sheet; dipping an epoxy resin, polyester resin, and thermoplastic resin to whole side of the nano cellulose sheet; and curing the dipped cellulose sheet paper to obtain reinforced plastics.

Description

Nano cellulose fiber reinforced plastic

The present invention is in the field of fiber reinforced plastics. Fiber-reinforced plastics are plastics made by impregnating carbon fibers, glass fibers, and aramid fibers with epoxy resins, polyester resins, and thermoplastic resins.

Carbon fiber and aramid fiber used in fiber-reinforced plastics are very expensive and are too expensive to be used in daily life.In fact, they are limited in use and are mainly used in the aviation industry. Glass fiber is relatively inexpensive but heavy in weight and glass. The controversy over the hazards of fiber also makes it inadequate for everyday use. Therefore, there is a need for a fiber that can be used for fiber-reinforced plastic that is easy to make, inexpensive, and not harmful.

The present invention is to make a fiber-reinforced plastic using inexpensive fibers such as carbon fibers, aramid fibers, and fibers that are not harmful to harmful glass fibers.

In order to solve the above disadvantages, in the present invention, by compressing and drying the nano cellulose extracted from the high pressure extractor of cellulose, which is a main material of plants, especially wood, impregnating the sheet paper with epoxy, polyester resin, thermoplastic resin, etc., it is cheap and not harmful. Strong nano cellulose reinforced plastics were made.

As discussed above, nano cellulose-reinforced plastics are inexpensive, not harmful to the human body, and their weight is light and strong, so they can be used in tight places for daily life, which is a great help for the industrial economy.

When cellulose extracted from plants, especially wood, is extracted several times in a high pressure extractor, nano cellulose is extracted, and the nano cellulose is compressed and thinly formed into a sheet shape and dried to form nano cellulose sheet paper having a tensile strength as strong as metal. It is also known as a super paper. If nanocellulose is impregnated with epoxy, polyester resin or thermoplastic resin to harden to form the reinforcement plastic of the desired shape, the nano cellulose sheet can make light and strong plastic. In addition, it is possible to achieve the object by forming a desired shape by mixing the nano cellulose not molded into sheet paper to epoxy or polyester resin, thermoplastic resin and the like. Alternatively, the fiber-reinforced plastic can be made by cutting nano cellulose sheet paper into a certain width to make a thin tape means, and weaving the tape means to cross each other to make cross woven sheet paper, and also impregnating with epoxy, polyester resin, and thermoplastic resin to cure it. have.
