Abstract
The invention relates to a preparation method of a novel environment-friendly fire-proof plate, which comprises a fire-proof material 1, wherein a grid flax 2 and a steel wire 3 are arranged inside the fire-proof material 1, the specification of the grid flax 2 is 23 x25 and 4.2 x5.2, and the steel wire is of a steel wire with 7 to 10 meshes and 37 to 39 wires, the grid flax 2 is provided with two layers, the steel wire is arranged between the two layers of the grid flax 2, and the fire-proof material 1 comprises the following raw materials by weight: 75 to 90 parts of magnesium chloride, 80 to 100 parts of magnesia, 8 to 12 parts of sawdust, 5 to 10 parts of coal ash and 6 to 8 parts of perlite powder. The 75 to 90 parts of magnesium chloride is added with water to be configured to a magnesium chloride solution of 20 to 28 degrees, and the magnesia, the sawdust, the coal ash and the perlite powder are added into the magnesium chloride solution to be uniformly mixed according to the formula. The novel environment-friendly fire-proof plate has the advantages of high strength, good flame-retardant performance and the like, the flame-retardant time can reach the highest standard A1 of the national flame-retardant material, and the product is qualified after being inspected by relevant department of the Ministry of Public Security.
Description
Technical field
The present invention relates to the preparation method of a kind of PLASTIC LAMINATED, particularly a kind of novel environment-friendly fire-proof plate.
Background technology
At present, materials such as glass fibre, rock wool and aluminium silicate wool are arranged all generally in the PLASTIC LAMINATED, this different materials is the essential material that China produces fireproof door for these years.The weak point of its existence is: this different materials all can produce toxic and harmful when burning.For this reason, State Council's indication is abideed by by China Ministry of Public Security, is defined in the steel fireproof door and fire-proof wooden door of China, bans use of the material that can produce any toxic and harmful.
Summary of the invention
The objective of the invention is to overcome the above-mentioned deficiency of prior art, and a kind of preparation method of novel environment-friendly fire-proof plate is provided, it does not contain the material that can produce any toxic gas.
Technical scheme of the present invention is: a kind of preparation method of novel environment-friendly fire-proof plate, it includes the fire prevention material, in the fire prevention material grid burlap and steel wire is arranged.
The further technical scheme of the present invention is: the grid burlap has two-layer, and steel wire is between the two-grid burlap.
The present invention further technical scheme is: the raw material weight prescription of fire prevention material is: magnesium chloride: 75-90 part, magnesia 80-100 part, wooden clouds: 8-12 part, coal ash: 5-10 part, crushed crude pearlite: 6-8 part, 75-90 part magnesium chloride is added the magnesium chloride brine that water is mixed with the 20-28 degree, get final product stirring in magnesia, wooden clouds, coal ash, the crushed crude pearlite adding magnesium chloride brine by prescription again.
The present invention is owing to adopt as above technical scheme, compared with prior art, has characteristics such as intensity height, fire resistance are good, and duration of fire resistance can reach national fire proofing highest standard A1, and product is up to the standards by relevant department of the Ministry of Public Security.
Below in conjunction with the drawings and specific embodiments detailed content of the present invention is further described.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
As shown in Figure 1: a kind of preparation method of novel environment-friendly fire-proof plate, it includes fire prevention material 1, in fire prevention material 1, grid burlap 2 and steel wire 3 are arranged, grid burlap 2 specifications are 23 * 25,4.2 * 5.2, steel wire 3 is the 7-10 order, specification is the steel wire of 37-39 silk, grid burlap 2 has two-layer, steel wire 3 is between two-grid burlap 2, the raw material weight prescription of fire prevention material 1 is: magnesium chloride: 75-90 part, magnesia 80-100 part, wood clouds: 8-12 part, coal ash: 5-10 part, crushed crude pearlite: 6-8 part, 75-90 part magnesium chloride is added the magnesium chloride brine that water is mixed with the 20-28 degree, again by filling a prescription with magnesia, the wood clouds, coal ash, stir in the crushed crude pearlite adding magnesium chloride brine and get final product.
The present invention is not limited to above-mentioned concrete structure, so long as add grid burlap and steel wire at PLASTIC LAMINATED, just drops within protection scope of the present invention.
