Magnesium cemented pressure plate and manufacturing method thereof

Abstract

The invention discloses a magnesium cemented pressure plate. The magnesium cemented pressure plate comprises the following raw materials in parts by weight: 42-56 parts of domestic waste, 8-16 parts of light-burned magnesium oxide, 5-12 parts of magnesium sulfate, 3-8 parts of magnesium chloride, 2-6 parts of magnesium hydroxide, 6-12 parts of aluminum hydroxide, 8-22 parts of nano silicon dioxide, 10-16 parts of sericite powder, 8-18 parts of glass fiber, 10-18 parts of epoxy resin, 12-32 parts of polyvinyl chloride resin, 1-3 parts of crosslinking agent and 0.3-0.8 part of stabilizer. A manufacturing method of the magnesium cemented pressure plate comprises the following steps: preparing the pressure plate materials; feeding the pressure plate materials into a mold; and performing pressurization, demolding, drying and edging to obtain the finished product. The pressure plate provided by the invention is environment-friendly and nontoxic, the fire-protection rating reaches Level A, and the pressure plate is favorable in wear resistance, heat resistance, water resistance and anti-freezing property and high in nail-holding power; and the manufacturing method is simple and low in production and use cost.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a magnesium gelled pressure plate and a manufacturing method thereof. Background technique [0002] The pressure board commonly used in the market is mainly cement pressure board, which is a new type of building board made of natural fiber and cement through pulping, molding, cutting, pressing and curing. It is widely used in civil and industrial buildings. . However, three wastes will be produced during the production process of cement pressure board, which is harmful to the environment around the manufacturing plant. Moreover, organic solvents, such as formaldehyde, are usually used in the manufacture of pressure boards, which brings hidden dangers to the safety of users. Traditional cement pressure boards use natural fibers as raw materials, so there is a large demand for natural fibers, and natural fibers exist and grow in nature, so the output is small and resour...

Problems solved by technology

However, there are still some places to be improved in the pressure plate made of the existing gel material, such as poor waterproof performance, easy to pulverize and mildew in wet conditions; the fire resistance level is not high, generally not up to A level; The strength is poor, it is not easy to fix when using, often need to use the support frame to fix
