Abstract
The invention relates to a fiber mesh plastic board, which is characterized by containing 0.5 to 60 percent of fiber by weight in a form of continuous fiber meshes, and the balance of thermoplastics; and at least one layer of the fiber meshes are arranged in the plastics. The fiber mesh plastic board adopts extrusion technology; a reinforced plastic board produced by the continuous fiber meshes significantly improves the performance of composite materials; boards can be produced continuously by extrusion molding technology and have far lower cost than that of compression molding technology; and products are easy to control and save processing energy consumption. The fiber meshes adopted by the invention have low price; the fiber exists in the boards in a tension state and can play the maximum supporting role; the extrusion molding technology results in high production efficiency and low investment of equipment; and the fiber mesh plastic board can adopt waste plastics, so the renewable utilization of materials is high. The plastic board product has wide range of application, and can be used for producing cabinets, package cabinets, filing cabinets, furniture, architectural templates, floors, wall panels, earthquake-resistant movable houses and the like; after the boards are reinforced by the fiber meshes, the strength and the rigidity can be greatly increased, so the board thickness can be reduced, and materials can be saved under the same usage request.
Description
Technical field: [0001] The invention belongs to the technical field of composite materials, and in particular relates to a fiber grid plastic board and a preparation method thereof. Background technique: [0002] With the development of the economy, fiber-reinforced plastics, as an environmentally friendly recyclable composite material, have made great progress and are widely used in various fields of the national economy. [0003] Fiber-reinforced plastics consist of two broad categories of materials: fibers and plastics. They play different roles on the properties of composite materials. The fiber as the skeleton material mainly plays the role of bearing external force, while the plastic acts as a bond and protects the skeleton material. An obvious fact is: under other conditions being the same, the longer the length of the skeleton material, the higher the strength of the composite material. [0004] Extrusion process is an important process of plastic product process...
