AI Technical Summary

Problems solved by technology

However, the above-mentioned various products have obvious disadvantages in use, such as: heavy stone, poor thermal insulation effect, increasingly scarce resources, and obvious safety hazards after installation (there have been many accidents in my country where stone hanging panels on external walls fell and killed people); The plastic board has poor aging resistance and is fragile; the ceramsite board is heavy and has potential safety hazards. Due to poor processability, the pattern and color are single; PVC board has poor aging resistance, is fragile, is not resistant to color change, and has a short service life; The oxidation resistance time of the external hanging board is short, and the on-site processability is relatively poor. Generally, it will be ugly after two or three years.
At the same time, the existing products have different degrees of pollution discharge and high energy consumption during production.

Abstract

The invention discloses a plant fiber plate for exterior walls. The plant fiber plate comprises, by weight, magnesium oxide, plant fibers, magnesium sulfate, OP-10, EVA (ethylene / vinyl acetate copolymers), antioxidants, curing agents, carboxymethyl celluloses and water. A method for preparing the plant fiber plate includes preparing materials; stirring the materials; mixing the materials with one another; manufacturing plant blanks; manufacturing the plant fiber plate. The plant fiber plate for the exterior walls and the method have the advantages that the raw materials for the plant fiber plate for the exterior walls are common raw materials on the market, the plant fiber plate is low in cost, large quantities of abandoned crops such as straw and sawdust are utilized, accordingly, waste can be turned into wealth, and resources can be comprehensively utilized; the plant fiber plate for the exterior walls is good in weather resistance and fire resistance, free of emission of waste gas, waste water and solid waste and high in heat preservation coefficient and is safe and environmentally friendly; the method for preparing the plant fiber plate for the exterior walls is easy to implement, high in productivity and suitable for industrial large-scale production, the plant fiber plate can be conveniently prepared by the aid of the method, and the like.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to a plant fiber board used for exterior walls and a preparation method thereof. Background technique [0002] Nowadays, in the construction of exterior walls of buildings, in order to ensure that the exterior walls have aesthetics and thermal insulation effects, exterior wall decoration hanging panels are often used. The traditional ones include stone, aluminum-plastic panels, ceramsite panels, PVC panels, and metal printing panels. Material. However, the above-mentioned various products have obvious disadvantages in use, such as: heavy stone, poor thermal insulation effect, increasingly scarce resources, and obvious safety hazards after installation (there have been many accidents in my country where stone hanging panels on external walls fell and killed people); Plastic panels have poor aging resistance and are fragile; ceramsite panels are heavy and have potential safety haz...
