Abstract
The invention relates to the technical field of the heat insulating fireproof coat, in particular to a preparation method of the heat insulating fireproof coat. The heat insulating fireproof coat comprises the following components by volume ratio: 5 to 6 of vermiculite with 0.5 to 2.5 mm of granularity, 0.8 to 1 of mica with 40 meshes of the granularity being larger than 95 percent, 0.5 to 0.6 of perlite with the volume weight less than 100kg/m<3>, 0.7 to 1.1 of light 325 meshes calcium carbonate , 0.8 to 1.1 of 42.5R portland cement , 0.01 to .002 of cement additive and 0.005 to 0.006 of silica white . The product disclosed in the invention has the advantages of good heat tolerance, high cementing strength and strong cracking resistance, and is widely applicable for the special heat insulating and fireproof field of fire dike.
Description
Technical field
The present invention relates to a kind of heat-insulating, fire-preventing technical field of coatings, the invention still further relates to the preparation method of this heat-insulating, fire-preventing coating.
Background technology
At present, what China's fire-proof and thermal-insulation coating generally adopted is to add expanded vermiculite, perlite with cement, and adds the thick matter heat-insulating, fire-preventing coating of various stopping composition, and the equipment that adopts is stirrer usually.This class frie retardant coating also exists not enough on the composition of its material and production technique, generally has cohesive strength not high, and ultimate compression strength is low to wait existing picture.Can not satisfy the high temperature impact when hydrocarbon fire, and its ultimate compression strength and cohesive strength descend obviously after freeze thawing repeatedly, can not satisfy design side to the fp requirement.Raising along with Chinese economic development and people's awareness of safety, environmental consciousness, country requires more and more higher to the heat-insulating, fire-preventing coating of safety in production usefulness, and storage tank district spill wall heat-insulating, fire-preventing coating has proposed higher technical indicator, develops a kind of novel spill wall heat-insulating, fire-preventing coating for this reason and is of great immediate significance.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides and a kind ofly form, have advantages such as good fire resistance, cohesive strength height, the anti-heat of exposing to the sun, high cracking resistance by vermiculite, perlite, mica, light calcium carbonate, silica-gel powder, cement additive, silicate cement.Especially its intensity index still can satisfy code requirement after freeze thawing 15 times.
For achieving the above object, the present invention adopts following technical scheme:
The special-purpose heat-insulating, fire-preventing coating of described spill wall, it forms its component and consumption following (parts by volume) by following:
Granularity is the vermiculite 5-6 of 0.5-2.5mm
The mica 0.8-1 of granularity 40 order sieving rate＞95%
Unit weight＜100kg/m
3Perlite 0.5-0.6
325 purpose light calcium carbonate 0.7-1.1
Silica-gel powder 0.005-0.006
Cement additive 0.01-0.02
42.5R silicate cement 0.8-11
The preparation method of the special-purpose heat-insulating, fire-preventing coating of described spill wall, it comprises the following steps:
(1), vermiculite, mica, light calcium carbonate, perlite, cement are dropped in the stirrer hopper in order, and cloth should be even, then the raw material in the stirrer hopper slowly is transported in the stir storehouse.
(2), start stirrer and stir and add cement additive and silica-gel powder restir after 5 minutes after 5 minutes, shut down and promptly produce finished product, the finished product loose volume weight is 420kg/m
3To 460kg/m
3
(3), measure the finished product loose volume weight, as exceed 420kg/m with standard container
3To 460kg/m
3Should adjust vermiculite and cement proportion,
Technical scheme the present invention has following positively effect owing to adopted as mentioned above:
(1), starting material are easily purchased, processing unit is simple, production technique is simple, easy to operate, product is nontoxic, advantage such as easy to use, cheap.
(2), remarkable, the cohesive strength high compressive strength height of fire protection flame retarding effect, the coating dry density is low, anti-expose to the sun hot good, splitting resistance strong, have advantage such as the hot freeze-thawing resistant of moisture-proof, can satisfy the all-mass index request of the frie retardant coating that is used for storage tank district spill wall, good practical reference value is arranged.
The present invention is through checking the key technical indexes:
The HC heating curve is adopted in the fire performance test.
