Abstract

The invention discloses a reinforced toughened plant fiber composite film and a preparation method thereof. The composite film is prepared from the following raw materials in parts by weight: 20-45 parts of straw extract fiber, 15-35 parts of towel gourd fiber, 20-40 parts of ramee, 10-30 parts of corn starch, 12-25 parts of chitosan, 6-17 parts of molecular sieve, 5-20 parts of polyvinyl alcohol, 5-15 parts of polycaprolactone, 2-6 parts of potassium tripolyphosphate, 2-7 parts of diethyl phthalate 1-5 parts of triethanolamine stearate quaternary ammonium salt, 2-8 parts of reinforcer, 5-25 parts of clearing agent and 6-20 parts of adhesive. The invention also discloses a preparation method of the composite film. The tensile strength of the plant fiber composite film is 16-25 MPa, the tearing strength is 75-105 MPa, and the plant fiber composite film has favorable stretching resistance and tear resistance. Besides, the preparation method is simple, has the advantages of accessible and common raw materials and lower cost, and is suitable for wide popularization and further expanded application.

Description

technical field [0001] The invention relates to the field of composite materials, in particular to a reinforced and toughened plant fiber composite film and a preparation method thereof. Background technique [0002] Plant fiber film is a kind of film with good biodegradability prepared by using plant fiber such as wood, cotton, hemp and other natural raw materials, and crop waste such as straw, straw, bagasse, etc. as raw materials. Due to the wide source and low price of plant fiber, and its excellent degradability, it can improve the problem of film pollution in today's environment. Therefore, fiber film has attracted much attention. However, just because the traditional plant fiber film is mainly made of some natural raw materials or crop waste, its strength and tensile properties are poor, and it is easy to be torn and deformed under the action of external force. Moreover, the traditional plant fiber film has poor water resistance, and its mechanical properties are gre...
