Abstract

The invention provides a fireproof insulation board and a manufacturing method thereof. The fireproof insulation board comprises a component A and a component B, wherein the component A comprises the following materials in parts by weight: 60-80 parts of magnesium oxide, 2-14 parts of talcum powder, 0.1-0.5 part of retarder, 0.01-0.05 part of cellulose ether, 0.02-0.1 part of hydrophobic rubber powder or 0.1-2 parts of organic silicon emulsion, 0.1-0.5 part of inorganic pigment, 16-26 parts of magnesium chloride, 5-10 parts of water glass and 70-90 parts of water; the component B comprises the following materials in parts by weight: 4-8 parts of first polystyrene particles, 2-4 parts of second polystyrene particles and 1-2 parts of third polystyrene particles. The fireproof insulation board has the advantages that the manufacturing open time in the board production process can be prolonged, the waterproofness and the tensile strength of the board can be improved, the fire resistance of the fireproof insulation board can be excellent and the problem of unachievable A fireproof grade is thoroughly solved; the fireproof insulation board is better in thermal insulation effect.

Description

technical field [0001] The invention relates to thermal insulation materials for buildings, more specifically, to a fireproof thermal insulation board and a manufacturing method thereof. Background technique [0002] At present, the existing thermal insulation boards on the market mainly include organic boards such as EPS boards and XPS boards. The fire performance of these boards is B2 or B1, which cannot reach the A-class standard. It can burn in the event of a fire, and will produce a large amount of harmful smoke, which will have a great impact on personal safety and environmental safety; while inorganic thermal insulation mortar, although its fire performance can reach Class A, has a high thermal conductivity and difficult construction. long. For this reason, rubber powder polystyrene particle insulation mortar and glass magnesium board have appeared in the market. Rubber powder polystyrene particle insulation mortar is composed of mortar and insulation particles. It i...

AI Technical Summary

Problems solved by technology

[0003] 1. Although the organic thermal insulation materials in the prior art have good thermal insulation effect, their fireproof performance is poor. Due to the limitations of their materials, the best fireproof performance can only reach B1 level;

[0004] 2. Existing inorganic thermal insulation materials, such as rock wool thermal insulation materials, although their fireproof performance can reach Class A, and their thermal insulation effect is also good, but because their main components are mineral fibers, they are extremely harmful to human health, especially in construction. On-site construction workers, due to inadequate protective measures, caused mineral fibers to penetrate into the skin, causing symptoms such as skin itching, redness, blisters, ulceration, etc., and in severe cases, they could be inhaled into the lungs by the human body, causing respiratory diseases, and even life-threatening;

[0005] 3. Existing thermal insulation materials such as inorganic thermal insulation mortar need to be prepared on the construction site and then applied to the wall surface of the building by workers. Although the fire prevention effect can reach A level, the insulation effect is not good, and because The quality of on-site preparation and batch application cannot be controlled, and since the thickness of each application is generally not more than 2cm, it is labor-intensive and time-consuming. For areas with high energy-saving requirements in the north, multiple batches of application are required, resulting in poor construction efficiency and long construction period;

[0006] 4. The existing thermal insulation mortar with rubber powder and polystyrene particles is made of a mixture of inorganic and organic materials. Although its thermal insulation effect is good, its fireproof performance can only reach B1 level, and because of its low strength, after it is made into a board, Extremely fragile and unable to meet the basic requirements of multiple handling from factory to construction site applications

Therefore, the insulation material is also constructed through multiple batches on site, which is also labor-intensive and time-consuming;

[0007] 5. Existing thermal insulation materials such as rock wool, inorganic thermal insulation mortar, rubber powder polystyrene particle thermal insulation mortar also have disadvantages such as poor waterproofness and easy water absorption, which will easily cause the thermal insulation effect to be greatly reduced after water absorption, and the strength and other indicators will also be seriously affected. influences
