Problems solved by technology

[0004] But these two kinds of methods all have certain shortcoming, the shortcoming of chemical foaming is: the bubble that forms is changed by the change of temperature, needs to have constant temperature device in practice, otherwise will not be able to control
When a fire breaks out and the temperature rises, the hydration products in ordinary cement will lose water and crack, which may cause the cement base to expand, deform and be damaged.
[0006] To sum up, although these heat insulation and fireproof materials have a certain effect of heat insulation and fireproof, the effect is still not good.

Embodiment Construction

[0010] This heat insulation and fireproof material is mainly composed of cement base, foaming agent and additives. Each cubic meter of finished product contains:

[0011] Cement base 350~600kg

[0012] Foaming agent 0.1~20kg

[0013] The additive is 50-250kg and the cement base is high alumina cement. The foam agent is composed of a foam initiator and a foam stabilizer. The additive is mainly composed of refractory powder, expanded perlite and vermiculite. Among them, the foam starter is a condensation product of fatty acid and ethylene oxide, and its chemical molecular formula is:

[0014] R-O-(C 2 h 4 O) n H wherein n≥5 foam stabilizers are polyoxyethylene and polyoxypropylene block polymers, and the chemical formula is:

[0015] H(C 2 h 4 O) a -(C 3 h 6 O) b -(C 2 h 4 O) c -OH wherein a≥5, b≥4, c≥1 The ratio of foam initiator and foam stabilizer is (10~15):1.

[0016] The following are preferred embodiments of the present invention:

[0017] The content of e...

Abstract

The invention refers to an adiabatic fireproof material prepared by high-aluminium cement and foaming agent and the preparing method. Its components: cement base 350-600 kg / m, foaming agent, 0.1-20 kg / m to the power 3, additive 50-250 kg / m to the power 3, the cement base being high-aluminium cement, the foaming agent composed of foam initiating agent and foam stabilizing agent. The method: before or after stirring the mixture of high-aluminium cement and additive by water, inject the foamed solution into the water, mix evenly, and make hardening reaction to prepare the material.

Description

Technical field: [0001] The invention relates to the technical field of heat-insulating and fireproofing materials and manufacturing methods thereof, in particular to a heat-insulating and fireproofing material mainly made of high-alumina cement and a foam agent and a manufacturing method thereof. Background technique: [0002] Now, whether it is an enterprise or a family, there are many documents that need to be collected, such as the company's account books, contracts, cash, family members' insurance policies, stocks or other various documents. Generally these articles all are deposited in safe box or safe room, although can prevent like this and lose, but just in case break out of fire, then consequence is disastrous. Therefore, people have developed thermal insulation and fireproof materials, which are used in products or facilities such as safes and walls. [0003] At present, the main raw material of general heat insulation and fireproof materials is ordinary portland...
