Abstract

The invention discloses a high-performance thermal-insulation fire-proof sound-insulation material, and belongs to the technical field of building material. The high-performance thermal-insulation fire-proof sound-insulation material is composed of, by mass, 40 to 50% of cement, 25 to 35% of glass microbead, 25 to 35% of rock wool chip, 2 to 4% of polypropylene fiber, 2 to 4% of polymer latex powder, 0.2 to 0.4% of cellulose ether, and 3 to 5% of wood fiber, wherein cement can be replaced by gypsum, and glass microbead can be replaced by perlite. Rock wool chip is recycled; waste is changed into valuables; the high-performance thermal-insulation fire-proof sound-insulation material is mainly used for parts with thermal-insulation demands, sound-insulation demands, and fire-proof demands, such as building internal wall thermal insulation, unheated space thermal insulation, elevator shaft sound-insulation layer, separating wall thermal insulation and sound insulation, and fireproof door core material.

Description

A kind of high-performance insulated fire sound-proof material

Technical field

The present invention relates to building material technical field, be specifically related to a kind of high-performance insulated fire sound-proof material.

Background technology

Rock wool belongs to inorganic materials, and rock wool adopts basalt, rhombspar etc. to be main raw material(s), and after high-temperature fusion, the manmade inorganic fibre be made up of high speed centrifugation equipment, has extremely strong insulated fire performance.A large amount of uses of rock wool for building, provide possibility for China builds more Green environmental-protection building, by effectively reducing energy consumption and carbon emission thus protection of the environment, for improving people's living environment, have made due contribution.

Get more and more in the rock wool manufacturer of China at present, rock wool has become topmost A level lagging material on market.But prolonging in continuous production process, because rock cotton board is cut by needs, thereby produce a large amount of rock wool chips, the treatment process of a lot of producer is that it is buried in underground, so both consumes a large amount of manpower financial capacities, and pollutes environment again.

Summary of the invention

The object of this invention is to provide a kind of high-performance insulated fire soundproof material, rock wool chip utilizes by it, is turned waste into wealth, and is mainly used in the position that buildings has thermal requirements; There is the position of sound isolation requirement; There is the position of fire protection requirement, as: the insulation of inner wall of building insulation, the insulation of non-heating space, elevator raise pugging, party wall and sound insulation and fireproof door core material etc.

In order to solve the problem existing for background technology; the present invention is by the following technical solutions: its mass percent formula consists of: cement 40-50%, glass bead 25-35%, rock wool chip 25-35%, polypropylene fibre 2-4%, polymer glue powder 2-4%, ether of cellulose 0.2-0.4%, wood fibre 3-5%; wherein cement can be replaced gypsum, and glass bead can be replaced perlite.

Production technique of the present invention:

(1) first select double-screw type stirrer by various additive and auxiliary agent by a certain percentage ratio mix;

(2) then mixture being inputted secondary blender---in forced action type agravic blender, mix with cement or gypsum, rock wool chip and fiber, and churning time should suitably lengthen;

(3) finally secondary mixture is inputted three grades of stirrers---in light-weight aggregate special-purpose stirring machine, mix with glass bead or perlite, strict control stirrer is slow-revving while, shorten churning time, avoid the breakage of light-weight aggregate.

Using method of the present invention is:

(A) powder proportioning: thermal insulation mortar configuration proportion must carry out on-the-spot proportioning according to materials specification, Measuring Precision is ± 2%;

(B) alr mode: alr mode should be stirrer and stirs: first add in agitator by water, again heat insulating mortar powder is put into agitator, stir 2 ~ 3min, stop stirring 1 ~ 2min and clear up the stirrer inwall not well-mixed slurry with water, stir 2 ~ 3min again, during stirring, other material must not be added; Heat insulation mortar must be used while allocating, and the slip prepared should be finished in 2 hours, be not finished slurry and land ash must not secondary stirring use;

(C) wet mixing mortar made, both can be used for wall plastering construction, can be made into sheet material again.

Rock wool chip utilizes by the present invention, is turned waste into wealth, and is mainly used in buildings not by the insulation at water enchroachment (invasion) evil position, as: inner wall of building insulation, the insulation of non-heating space and fireproof door core material etc.

Embodiment:
