Problems solved by technology

[0004] The purpose of the present invention is to provide a straw fiber composite material and its preparation method to solve the problem that when the traditional preparation method prepares the composite material through the plant fiber, the roughness of the plant fiber forms voids and defects on the interface, and the mechanical properties of the composite material are very poor. Strong, so when the plant fiber content is high, the composite material shows obvious brittleness, and it is difficult to obtain a composite material with excellent performance. The present invention is easy to use, simple to operate, highly systematic, and strong in practicability

Embodiment 1

[0042] The present invention provides a technical solution: a method for preparing a straw fiber composite material, which specifically includes the following steps:

[0043] S1: First, the straw waste is crushed by the coarse mill, and then the fine material is screened through the screen, and then the coarse material is left on the screen. The screen size of the screen is 1mm, and the standard mesh number is 18;

[0044] S2: collect the coarse material, and then continue to process and grind the coarse material through the refiner, and then sieve it through the screen in step S1;

[0045] S3: Pour the screened fine material into the extraction tank, then add water, and then stir to allow it to settle into the extraction tank;

[0046] S3: Then take out the bottom 10% of the sedimentation liquid in the extraction tank;

[0047] S4: filter out the remaining part in the extraction tank in step S3, and then put it into a steamer at 100°C for cooking for 60 minutes;

[0048] S5...

Abstract

The invention relates to a straw fiber composite material and a preparation method thereof.The preparation method includes the steps of straw waste smashing, coarse material collecting, extracting, cooking and adhesive adding, and therefore the adhesive is added in the preparation process, so that fibers have higher affinity, the mechanical structure is more flexible, and the straw fiber composite material is more environmentally friendly. The composite material does not show obvious brittleness, the composite material with excellent performance can be obtained, the preparation is simple, extracted impurities can be poured into an original extraction tank again and can be repeatedly poured for multiple times until precipitates are reduced to the minimum, resources are fully utilized, filtered water can be repeatedly used for multiple times, and the cost is low. Waste water does not need to be discharged, so that the processing cost is reduced, and water resources are saved.

Description

technical field [0001] The invention relates to the technical field of fiber preparation technology, in particular to a straw fiber composite material and a preparation method thereof. Background technique [0002] Because plant fiber is low cost, easy to obtain and easy to process, has strong plasticity and compatibility, and has good stability with other colloids and weak acid-base solutions, plant fiber has strong compatibility with composite materials. In the traditional preparation method, when the composite material is prepared from plant fiber, the roughness of the plant fiber forms voids and defects on the interface. Due to the strong mechanical properties of the composite material, when the content of the plant fiber is high, the composite material shows obvious brittleness. , it is difficult to obtain composite materials with excellent performance. [0003] To sum up, the present application proposes a straw fiber composite material and a preparation method thereo...
