A kind of dustproof mortar and preparation method thereof

Abstract

The invention discloses a dust-proof mortar and a preparation method thereof. In terms of parts by mass, the dust-proof mortar comprises: 100-850 parts of aggregate, 150-900 parts of cementitious material, 0-100 parts of rubber powder, cellulose 0-10 parts of ether, 1-10 parts of dustproof agent, 0.5-5 parts of coupling agent, 0-10 parts of early strength agent and 0-50 parts of other functional additives. In the present invention, by adding the dustproof agent and the coupling agent, the prepared dustproof mortar will not produce a large amount of dust in the process of mortar production and use, effectively preventing the generation of dust; further reducing the pollution to the environment and the health of personnel Impact.

Description

technical field [0001] The invention belongs to the technical field of mortar, and more specifically relates to a dust-proof mortar and a preparation method thereof. Background technique [0002] Mortar is a bonding substance used in building bricks. It is composed of a certain proportion of sand and cementing materials (cement, lime paste, clay, etc.) and water. It is also called mortar and mortar. Commonly used mortars include cement mortar, mixed mortar (or cement-lime mortar), lime mortar and clay mortar. [0003] Affected by the composition of mortar, there is often a lot of dust in the production and use of mortar at present; the dust-generating substances in mortar are mainly binders and modifiers of very fine components, and its main characteristics are small particle size and high density. It is relatively light, and under the action of mechanical vibration or other external forces, it will cause the emission of dust. During the production process of mortar, the du...

Problems solved by technology

[0003] Affected by the composition of mortar, there is often a lot of dust in the production and use of mortar at present; the dust-generating substances in mortar are mainly binders and modifiers of very fine components, and its main characteristics are small particle size and high density. It is relatively light, and under the action of mechanical vibration or other external forces, it will cause the emission of dust. During the production process of mortar, the dust generated by mechanical stirring or scattering during transportation will affect the physical and mental health of production workers and pollute the production equipment in the workshop. and the working environment; during use, when the mortar is poured into the water and stirred, the dust generated will affect the health of the construction workers and pollute the local space of the decoration

[0004] At present, dust emission is suppressed by introducing fluid additives into the mortar, which is beneficial to the protection of workers and the protection of factories or local environments. These fluid additives are mainly composed of non-polar hydrocarbon-containing organic substances, mainly mineral oil and paraffin oil. , paraffin, polyolefin or a mixture of these substances, by adding at least one of the aforementioned fluid additives to the mortar composition to achieve the purpose of suppressing dust emission; but the aforementioned fluid additives all have a certain hydrophobic effect, the more Large, the difficulty increases when mixed with water, increases the stirring time, and reduces the construction efficiency. At the same time, these substances contain a small amount of organic solvents or volatile small molecules, which will have a certain impact on the health of workers after use. , will cause some pollution to the environment
