Embodiment Construction

[0033] Below in conjunction with embodiment the present invention will be further described:

[0034] 1. The ingredients of diatomite flame retardant foaming agent are composed of the following components by weight percentage: 52% of dried diatomite, 8% of high-viscosity attapulgite clay powder, 24% of sodium bicarbonate, alkylbenzenesulfonic acid Sodium 13.8%, sodium polyacrylate 0.8%, sodium pyrophosphate 0.5%, ammonium polyphosphate 0.5%, and zinc borate 0.4%.

[0035] The production method of the diatomite flame-retardant foaming agent: input the ingredients of the diatomite flame-retardant foaming agent into the mixer for stirring, and after stirring evenly, input it into the mill for grinding, the particle fineness is ≤0.044 mm, and the package is The finished product of diatomite flame retardant foaming agent.

[0036] The production method of the dried diatomite is as follows: ① put the raw ore of diatomite into the pulverizer for pulverization, and the particle finen...

Abstract

The invention discloses a diatomite flame-retardant foaming agent. According to the key technical scheme, the diatomite flame-retardant foaming agent is prepared from dried diatomite, attapulgite clay powder with high viscosity, sodium bicarbonate, sodium alkyl benzene sulfonate, sodium polyacrylate, sodium pyrophosphate, ammonium polyphosphate and zinc borate, wherein all the components are stirred, ground to form powder and packaged, thereby obtaining a finished product of the diatomite flame-retardant foaming agent. After the diatomite flame-retardant foaming agent is stirred at a high speed by adding water, a great quantity of gas is released quickly, so that a porous foam slurry is formed. After the porous foam slurry is sprayed from a high-pressure water gun, the porous foam slurry can be used for performing fire extinguishment directly, wherein the surface layer of a combustible material is stably shielded by the foam slurry, so that a foam slurry membrane is formed. Thus, the combustible material is rapidly prohibited from coming into contact with the air. As a result, the combustible material is prevented form burning continuously, i.e., the purposes of flame resistance and fire extinguishment are realized. The diatomite flame-retardant foaming agent is suitable for the production of light-weight flame-retardant board materials, light-weight flame-retardant wall bodies and flame-retardant sound-attenuating and noise-reducing products.

Description

technical field [0001] The invention relates to a foaming agent, in particular to a diatomite flame-retardant foaming agent. Background technique [0002] Urban noise seriously affects the normal life and personal health of urban residents. Urban noise mainly refers to traffic noise, factory noise, construction noise and social life noise. It has become one of the conspicuous urban environmental pollution problems. [0003] To control noise, measures such as damping, sound insulation, sound absorption, muffler, personal protection, and building layout are usually taken to minimize or reduce the vibration of the sound source, absorb the sound energy in propagation, and set up obstacles to reflect all or part of the sound. Reduce the effect of noise to achieve the purpose of controlling noise. [0004] Usually, sound-absorbing materials are used to produce some sound-absorbing panels, sound-insulating walls, sound-absorbing nets and silencers to control noise pollution, and ...
