Problems solved by technology
[0003] In addition, bagasse is a kind of agricultural waste product. If the resources can be reused, good economic and social benefits can be obtained. Therefore, the composite board made of bagasse is prone to mildew, browning and insects, which affects the appearance and service life of the composite board.
Traditional anti-corrosion methods usually use bleaching, but since bleaching mostly uses oxidation methods, the anti-corrosion performance of composite panels will deteriorate after a period of use

Embodiment Construction
[0021] The proportion of raw materials in this embodiment is as follows: bagasse: 58 parts, graphite powder: 12 parts, graphite powder particle size is 40-60 mesh, flame retardant: 4 parts, urea-formaldehyde resin binder: 1 part, talcum powder: 3 parts parts, water: 22 parts.
[0022] Graphite powder has a small particle size, the highest specific surface area and structure, and is a good conductive filler. The amount of graphite used is determined according to the test results. When the amount of graphite added is less than 4 parts, the surface resistance drops slowly, and when it is more than 3 parts, the surface resistance drops sharply. When the graphite added amount is more than 12 parts, the surface resistance drops slowly. From the analysis of the conductive mechanism of the composite material, it can be known that when the addition amount is less than 4 parts, the conductive network of graphite is not formed, and the surface resistance decreases slowly; with the incre...

Abstract
The invention discloses a building template used for a mine. The building template is characterized by being manufactured from the following raw materials: 58 parts of bagasse, 12 parts of graphite powder with a particle size of 40-60 mesh, 4 parts of a flame retardant, 1 part of a urea-formaldehyde resin adhesive, 3 parts of talc powder and 22 parts of water. The building template is manufactured through the following steps: (1) purifying the bagasse; (2) crushing the purified bagasse and screening out bagasse particles; (3) carbonizing the bagasse particles; (4) accurately metering the graphite powder, the bagasse particles, the flame retardant, the urea-formaldehyde resin adhesive, the talc powder and the water in proportion, thermally mixing to 115-125 DEG C by virtue of a high-speed mixer, and cold-mixing to 40-60 DEG C; (5) extruding; and (6) shaping to obtain the building template. The obtained building template has the characteristics of good static resistance, flame retardancy and mechanical performance.
Description
technical field [0001] The invention relates to the field of building materials, in particular to a building formwork for mines. Background technique [0002] When the mine is mined, the suspended dust and the template rub against each other, and the positive and negative charges are redistributed between them, and the positive and negative charges are accumulated on the template and the dust respectively. When the static charge accumulates to a certain extent (it is generally believed that the surface resistance of 108Q is the lowest limit to prevent static accumulation), it will discharge sparks, which may cause fire or gas explosion. There are two ways to prevent electrostatic hazards: one is to reduce the generation of static charge by reducing or preventing friction; the other is to leak the generated static charge as soon as possible to avoid a large accumulation of static electricity. In most cases, it is difficult to reduce the generation of static charge, and the p...
