Abstract
The invention discloses an inorganic light thermal insulating wallboard and a manufacturing method thereof. The inorganic light thermal insulating wallboard comprises the following components in parts by mass: 10-30 parts of cement, 40-60 parts of coal ash, 10-15 parts of waste slag, an inorganic foaming agent accounting for 3-5% of the cement, and an assistant accounting for 0.05-0.5% of the inorganic foaming agent, wherein the inorganic cement foaming agent is 90-95% hydrogen peroxide and 5-10% of ammonium carbonate. The manufacturing method of the inorganic light thermal insulating wallboard comprises the steps of mixing the cement, the coal ash and the waste slag with water to form concrete grout, adding the inorganic cement foaming agent and the assistant to the concrete grout, stirring, allowing concrete to be foamed rapidly, casting the foamed concrete into a mold, and allowing the foamed concrete to be solidified, demolded and stacked automatically and cured naturally. The inorganic light thermal insulating wallboard is low in heat conductivity coefficient, good in noise control and sound-proof effect, fire-proof, low in volume-weight, moderate in strength, nontoxic and odorless, and insulates heat. Raw materials are easy to obtain, the cost and equipment investment are low, the technological operation is simple, and the wallboard takes effect rapidly, and is worth for extensive popularization and application.
Description
Technical field
The present invention relates to industry and the foam concrete block manufacturing that covil construction hand walls and roofs and heat insulating use, be specifically related to a kind of inorganic light weight thermal insulation wall plate and manufacture method thereof.
Background technology
Along with the urban house construction to energy-conservation mandatory code requirement, the inorganic light weight thermal insulation wall plate market requirement that various industry and covil construction hand walls and roofs and heat insulating use is huge.The exploitation of the environmental protection and energy saving building materials that various novel technology contents are higher, produce just in time.
At present, the kind of various energy-conserving and environment-protective is a lot of in the building materials market, and performance characteristics is respectively arranged.But performance is single, with low content of technology, on the high side mostly, is difficult for promoting the use of.
Summary of the invention
Technical problem to be solved by this invention provides a kind of inorganic light weight thermal insulation wall plate and manufacture method thereof, has foam performance characteristics excellent, with low cost.
For solving the problems of the technologies described above, the invention provides a kind of inorganic light weight thermal insulation wall plate, it is characterized in that, comprise that following quality is than component: 10～30 parts of cement, 40～60 parts in flyash, 10～15 parts of abandoned mine slags, and the inorganic foaming agent of cement deal 3～5%, the auxiliary agent of inorganic foaming agent deal 0.05～0.5%; The quality of described inorganic type cement blowing agent is the volatile salt of 90%～95% hydrogen peroxide and 5%～10% than component.
The manufacture method of inorganic light weight thermal insulation wall plate of the present invention may further comprise the steps:
With 10～30 parts of cement, 40～60 parts in flyash, 10～15 parts of proportionings of abandoned mine slag are mixed, and add water and generate concrete slurry,
With the inorganic foaming agent of described cement deal 3～5%, the auxiliary agent of inorganic foaming agent deal 0.05～0.5% joins in the above-mentioned concrete slurry after stirring in air and activating, and stirs, and concrete foams rapidly;
Foamed concrete is molded into mould;
Treat that foamed concrete solidifies voluntarily;
The foam concrete block demoulding, piling, natural curing.
The main technical parameters of inorganic light weight thermal insulation wall plate of the present invention is:
1, unit weight 300～800kg/m
3,
2, ultimate compression strength 0.3～3.5MPa,
2, thermal conductivity 0.08～0.125W/m k,
3, water-intake rate 10～25%,
4, noise-proofing absorbs noise ability 0.09～0.19%, reducing noise 30～50db,
5, fire resistance reaches the A grade standard, the fire endurance of 200mm slab 800 ℃＞4 hours,
6, pH value is 7～8.
Beneficial effect: inorganic light weight thermal insulation wall plate of the present invention is a kind of novel environment friendly materials for wall.Its thermal conductivity is low, and heat insulation and preservation effect is good, and the noise control soundproof effect is good, fire prevention, and the little quality of unit weight is light, and moderate strength is nonpoisonous and tasteless.Feel has thick and heavy sense, viscoelastic good toughness.Every safe, insulation, sound insulation, fire resistance are better than the state compulsion standard.
Simultaneously, the starting material of inorganic light weight thermal insulation wall plate of the present invention are easy to get, and cost is low, and facility investment is few, and technological operation is simple, and instant effect is worth widely applying.Adopt this composite inorganic whipping agent to be used for to use foaming machine when cement foamed, directly add to stir in the cement grout and get final product.It is fast to bubble, and gas release is large, uniform in foaming; Foam cement solidifies voluntarily, natural curing, manpower-free's maintenance.Therefore, have foaming effect advantage good, with low cost, safe and convenient to use, be suitable for scale operation, should vigorously promote the use.
