Abstract
An insulating composition is prepared from silicate cement, foam polystyrene plastics, cement additive, water-reducing agent, disperser, sepiolite as reinforcing agent, adhesive. Its advantages are high thermal insulation and strength, and high resistance to water and moisture.
Description
Technical field: the present invention relates to a kind of heat-insulation and heat-preservation material, relate in particular to a kind of cement and polystyrene thermal insulation composite material that is used for roof, body of wall heat-insulation and heat-preservation.
Background technology
Construction work mass consumption heat preserving and insulating material, as building roof, thorough body of wall, this type of heat preserving and insulating material need not bear too big weight, but its heat-insulating property will be got well, it is light that quality is wanted, and water resistance will be got well, and traditional heat-insulation and heat-preservation material for building comprises cement vermiculite, cement perlite and overhead heat insulation plate; The gas concrete piece though these heat-insulation and heat-preservation materials can play the effect of certain heat-insulation and heat-preservation, exists shortcoming on the high side, moistureproof, that water resistance is relatively poor, and particularly the gas concrete piece also exists the problem of the waste land resources and the energy; At present, utilize used foamed plastics, cement to do that raw material is made the roof insulation layer or the heat-insulating and heat-preserving wall brick has become trend.But inventor's on the-spot investigation is found: this heat preserving and insulating material major part is that two kinds of raw materials simply mix, thereby the roof heat insulation thermofin of made or its density of wall body brick, heat-proof quality, water-intake rate, ultimate compression strength do not reach the requirement of construction work to the heat-insulation and heat-preservation material property.
Summary of the invention: the heat-insulation and heat-preservation material manufacturing process of utilizing cement, polystyrene manufacturing at present is too simple in order to overcome, the heat preserving and insulating material performance is difficult to the problem of meeting the requirements of, and order of the present invention provides a kind of intensity height, waterproof, fire prevention, cement and polystyrene thermal insulation composite material that heat preservation and insulation is good.
Technical scheme of the present invention realizes in the following manner:
A kind of cement and polystyrene thermal insulation composite material, it comprises that mainly following raw material and composition by weight form than preparation:
Silicate cement 4～8 (part)
Polystyrene foamed plastics 0.8～1 (part)
Cement additire is an amount of
Technical scheme of the present invention can also realize in the following manner:
Silicate cement 4～8 (part)
Polystyrene foamed plastics 0.8～1 (part)
Cement additire 0.01～0.05 (part)
Water is an amount of
For intensity, the heat preservation and insulation that improves this thermal insulation composite material, the cement additire that the present invention selects for use is sepiolite, water reducer, whipping agent and diffusant, and components by weight percent is than being sepiolite between each additive: water reducer: (whipping agent+diffusant)=35～50: 50～80: 10～15
Be further to improve the intensity of this thermal insulation composite material, the present invention also selects for use and accounts for the gross weight ratio of component and be: 0.125～0.25 part tackiness agent.
Water reducer is preferably: TM retardation water reducing agent (Zhengzhou three chemical building material factories), FDN-1 concrete low-alkali high-efficiency water reducer (Zhengzhou three chemical building material factories), FDN-2 concrete high efficiency water reducing agent (Zhengzhou three chemical building material factories).

It is 425# that silicate cement adopts label.
Tackiness agent is: polyvinyl alcohol, water glass, CMC, polymeric amide.
Preparation technology is: raw material cement, waste old polystyrene foamed plastic that purify to pulverize are mixed add suitable quantity of water and stir, add additive stirring, moulding base, natural curing.
This cement and polystyrene thermal insulation composite material moulding base structure comprises heat insulating board for roofing layer, heat insulation wall brick,
Be provided with insulation hole vertical, even, that be arranged in parallel in the heat insulation wall brick, the aperture is that 10-15mm, pitch-row are 30-80mm.
Inventive point of the present invention is to utilize waste old polystyrene foamed plastic and silicate cement to make raw material, and selects for use suitable cement additire to improve its various performances; Positively effect of the present invention is:
1, utilizes waste old polystyrene foamed plastic to make raw material, provide a channel of handling to white pollution problems; This heat-insulation and heat-preservation material has good heat preservation and insulation; Reduced the cost of manufacture of lagging material, through detailed calculated, the cement perlite thermal insulation layer manufacturing cost that the insulating that the present invention makes is suitable with heat-insulation and heat-preservation reduces by 34.8%.
2, this heat-insulation and heat-preservation material has multiple use, can make roofing heat preservation and insulation, also can make the heat-insulating and heat-preserving wall brick.
3, in this heat-insulation and heat-preservation material because of having added suitable water reducer, diffusant, sepiolite toughener and tackiness agent, the composition board heat preservation and insulation is improved, and the also more original polystyrene cement of its waterproof, humidity resistance and intensity heat-insulation and heat-preservation material matrix material increase.
4, in the heat-insulating and heat-preserving wall brick that the present invention makes, because the setting of insulation hole, further improve its heat preservation and insulation, simultaneously, insulation hole further saving starting material are set, reduce cost, and when building a wall body, cement-bonded material can pierce and form fourth of the twelve Earthly Branches spike in the hole with adjacent two wall body bricks bonding one.
