Embodiment 1

[0071] Embodiment 1: Fiber-plastic composite material and preparation method thereof

[0072] This embodiment provides a fiber-plastic composite material, the preparation method of which includes:

[0073] (1) Breaking the woven fabric, then breaking the fabric into a fluffy state and repeating 3 times, using airflow separation to remove metal fragments and particles in the fabric, and finally combing 2 times to obtain the treated textile fiber, The volume of the treated textile fiber is three times that of the textile, and it is a uniform and completely separated single fiber or a fiber in a yarn structure;

[0074] (2) Extrude the processed textile fibers, plastics and auxiliary materials under the conditions of 200°C and 100r / min for mixing and volume reduction to obtain a bulk fiber-plastic mixture with a density of 1200kg / m 3 , and then cool the fiber-plastic mixture to 140°C; wherein the weight ratio of textile fibers, plastics, and auxiliary materials is 1:0.5:0.2.

Abstract

The invention discloses a fiber-plastic profile container bottom plate and a preparation method thereof, and belongs to the technical field of composite materials. The bottom plate body of the fiber-plastic profile container bottom plate provided by the invention takes the fiber-plastic composite material prepared from the waste textile fabric and the waste plastic as a raw material, so that the cost is low, the fiber-plastic profile container bottom plate is green and environment-friendly, and meanwhile, the waste textile fabric and the waste plastic are recycled, and therefore, the container bottom plate has an extremely high application prospect in the field of containers; the fiber-plastic composite material used by the fiber-plastic profile container bottom plate provided by the invention has more excellent mechanical properties than a single component in the fiber-plastic composite material, so that article loss caused by damage of the container bottom plate can be reduced to a certain extent by using the container bottom plate; the fiber-plastic profile container bottom plate further comprises the hard wear-resistant layer, the hard wear-resistant layer has the advantage of being high in wear resistance, and the risk that the container bottom plate is damaged can be further reduced.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and in particular relates to a fiber-plastic profile container bottom plate and a preparation method thereof. Background technique [0002] As a mature product, containers are not only used in cargo transportation, but also widely used in more fields, such as special equipment boxes, storage boxes, temporary residences, offices, showrooms, etc. The floors used in containers are also becoming more and more diversified. According to the different materials, they can be divided into wooden floor, bamboo floor, plastic floor, steel floor, fiber cement pressure plate, etc. [0003] Compared with other container floors, the plastic bottom plate is light in weight and simple to prepare. Therefore, the most commonly used container bottom plate is the plastic bottom plate at present. However, plastics are not easy to degrade, and long-term use of plastic bottom plates will aggravate environme...
