Summary of the invention
In order to solve the problems of the technologies described above, the present invention provides a kind of fire prevention quick-dry type spray material.
Its technical solution is:
A kind of fire prevention quick-dry type spray material, this spray material is composed of the following components by weight ratio:
200 parts of silicate cements
20~40 parts of water-ground limestones
8~30 parts of additives
40~70 parts of accelerating chemicalss
5~15 parts of wilkinites
120~135 parts in water,
Said additive is composed of the following components by weight ratio:
5~15 parts of sodium lignosulfonates
2~8 parts of calcium stearates
0.8~2 part of Xylo-Mucine
0.2~2 part of sodium alkyl benzene sulfonate
4~30 parts of terra albas
12~30 parts of water reducers
10~30 parts of hardening accelerator.
Wherein, mainly the acting as of each component in the additive: sodium lignosulfonate is an anionic surface active substances, and cement is had absorption and dissemination, can improve physicals, reduces water simultaneously, improves workability; Calcium stearate is a tensio-active agent, simultaneously the accelerator for hardening effect is arranged also, in the solidification process, produces calcium class material, improves density; Xylo-Mucine is a tensio-active agent, as dispersing material, helps to form water-soluable gel; Sodium alkyl benzene sulfonate is a tensio-active agent, as dispersing material, helps to form water-soluable gel; Terra alba is a flame-retardant composition, plays early strength function simultaneously, improves rheological and wall built-up property; Water reducer is chosen aliphatic high-efficiency water reducing agent, can lower adsorptive power between the silicate cement particle, reduces water consumption, improves workability; Hardening accelerator can shorten set time, improves early strength.The above-mentioned weight part ratio range of the combination of these components and each component; Confirm that through a large amount of tests the present invention is prevented fires, and coating that the quick-dry type spray material forms has the excellent balance of above-mentioned toughness, flowability, wall built-up property and fire-retardant burnback resistance.
Above-mentioned bentonitic weight part proportion optimization is 10~12 parts, and the weight part proportion optimization of above-mentioned calcium stearate is 6~8 parts, and the weight part proportion optimization of above-mentioned terra alba is 6~12 parts.
A kind of preparation method of the quick-dry type spray material of preventing fires may further comprise the steps:
Choosing sodium lignosulfonate, calcium stearate, Xylo-Mucine, sodium alkyl benzene sulfonate, terra alba, water reducer mixes with hardening accelerator and by above-mentioned weight part proportioning and obtains additive; Again additive and water are mixed by above-mentioned weight part proportioning; Silicate cement, water-ground limestone, accelerating chemicals and wilkinite with above-mentioned weight part after mixing is accomplished place mixer in the lump; Mix, the quick-dry type spray material promptly obtains preventing fires.
Useful technique effect of the present invention is:
The present invention is keeping high surfaces to spray on the intensity based, has the low characteristics of spraying rebound degree, and has wall built-up property and flowability and high toughness preferably, has good fire-retardant burnback resistance after condensing; In addition, raw materials used all can the purchase from market of the present invention obtains, wide material sources, and also price is lower.
