According to the present invention, the lightweight fiber fireproof coating material has characteristics of high durability, excellent thermal insulation property, low thermal conductivity, low heat capacity, good thermal stability, and strong cold-hot impact resistance; the preparation process is simple, and especially when the complex member is built, no gap is left; the adhesion is excellent, and the direct construction in any angles can be performed on the anchor-free flat steel plate, and no bounce is generated after the adhesion; and the special binder is added so as to improve the use strength and meet the use requirement of the part having high thermal insulation and high strength requirements.
Description
Technical field
The invention belongs to fire resisting material field, particularly relate to the fire-resistant coating of a kind of light fibre and preparation technology thereof.
Background technology
Along with being becoming tight day of resource, the energy in world wide, save energy, protection of the environment are the problems that various countries pay much attention to, and especially on Industrial Stoves, save energy and reduce the cost and stand in the breach especially.In the technology of various save energy, thermal insulation technology due to energy-saving effect remarkable, invest less, easy construction and being widely used.
Through By consulting literatures, in the selection of light heat insulation material material, domestic and international industrial heat-insulation insulating refractory is of a great variety, but respectively there are relative merits: as the diatomite brick in " New Building Materials " the 8th phase in 1993 " research of a diatomite light high-strength heat preservation material " literary composition such as Zhang Xiwen, take pearlstone as admixture, although thermal conductivity very low (0.12W/m.K), heat insulation effect is better, but its intensity is not very high, and maximum operation (service) temperature only has 800 DEG C; Aluminosilicate property refractory fiber blanket use temperature about 1100 DEG C, but construction inconvenience; Alumina Foam light cinder brick working temperature about 1500 DEG C, light silicious brick working temperature about 1550 DEG C, use them to build kiln by laying bricks or stones and produce very large gap, thermosteresis is large, and its cost is higher.
Improving further in the research of heat preserving and insulating material properties, at present, domestic rarely seenly have development report or patent that to smear or project material about fiber.We are through having studied intensively the features of above various lagging material for this reason, think that heat preserving and insulating material mainly contains the requirement of following 3 aspects: 1, use temperature wants high, minimumly on various kiln will reach 1200 DEG C; 2, construction requirement is convenient, and labour intensity can not be too large, freely can construct on polymorphic structure; 3, good heat-insulation effect, thermal conductivity is low.
Therefore, the selection of material of main part and the selection of bonding agent particularly important, particularly form of construction work to meet shaped piece can be good at construction.Feature of the present invention is: 1, use refractory fiber cotton to be main raw material, admix one or more admixtures, make heat insulating refractory materials use temperature high; 2, the construction of this heat insulating refractory materials is very convenient, can directly smear on shaped piece or project construction; 3, volume density is little, and heat conduction is low.
Summary of the invention
The present invention relates to the fire-resistant coating of a kind of light fibre and preparation technology thereof, improve intensity and the use temperature of lightweight refractory, improve workability simultaneously, can construct in the mode of smearing.
The technical solution adopted in the present invention is:
The fire-resistant coating of a kind of light fibre by refractory fiber cotton, high-alumina cement, alumine powder, lost article powder can be burnt and bonding agent forms, add water after stirring and construct in the mode of smearing.
Described coating feed composition weight percentage is: refractory fibre 20 ~ 40%, high-alumina cement 15 ~ 35%, and alumine powder 5 ~ 25%, can burn lost article powder 5 ~ 15%, and bonding agent is 1 ~ 5%.
Described bonding agent is polyvinyl alcohol.
Described preparation technology for first by refractory fibre, alumine powder, can burn lost article powder, bonding agent mixing, the water of additional 20 ~ 50%, pack after stirring, then working-yard is transported to, when constructing at the scene, then add high-alumina cement powder, being stirred to suitable state can construct, constructional method takes streak method, by material binding on construction body.
The invention has the advantages that: the first, employing refractory fiber cotton is main raw material, and have high durability and excellent heat-insulating property, its thermal conductivity is low, and thermal capacitance is little, Heat stability is good, and cold-hot impact is strong, has the performance of opposing physics, chemical action; The second, its preparation technology is simple, especially when building complex component by laying bricks or stones, can accomplish not stay gap to construct; 3rd, its tack is excellent, can, without direct construction arbitrarily angled on the plane steel plate of anchoring piece, adhere to rear without bounce-back; 4th, environmentally safe, easy construction, and operating environment is improved greatly.
Embodiment
Below by non-limiting example, essential characteristic of the present invention and construction are described.
The material component selected is: staple length is the refractory fiber cotton of 0 ~ 20mm, and granularity is the high-alumina cement of 0.088 ~ 0mm, and granularity is the alumine powder of 0.088 ~ 0mm, and granularity is the burnt lost article powder of 0.074 ~ 0mm.
First be refractory fibre 30% by the weight ratio of material component, high-alumina cement 18%, alumine powder 13%, can burn lost article powder 15%, bonding agent is 4% prepare material, and then external adding water stirs 10 minutes, the consumption of water is 40% of material component siccative gross weight, finally adds high-alumina cement 24%, stirs 8 minutes.
The miscellany prepared as stated above is smeared shaping in Standard Module, and then through 110 DEG C of x24h dryings, 1200 DEG C of x3h burn till.By the countries concerned's standard, actual measurement physical and chemical index is: volume density 110 DEG C of x24h are 1.Og/cm
3, 1200 DEG C of x3h are 1.16g/cm
3; Compressive strength 110 DEG C of x24h are 5MPa, and 1200 DEG C × 3h is 2MP; Strength at normal temperature 110 DEG C of x24h are 3.4MPa, and 1200 DEG C of x3h are 1.2MP; Linear change rate is for ~ 0.30% after 1200 DEG C of x3h burn; Thermal conductivity is 0.25W/m.K.
In order to verify its construction projection, spreading property, on vertical steel plate, carry out projection construction, result shows that its workability is excellent, can at the construction on steel plate of any angle, and tack is good, does not rebound simultaneously.
