Abstract
The invention discloses a foaming cement which is prepared by adopting cement, sand, S95-level grounded furnace slag, reinforcing agent, foaming agent, polymer and fiber, with the following mass proportion: cement : reinforcing agent equals to 50 : 3, cement : S95-level grounded furnace slag : sand equals to 10 : 4 : 3, and cement : polymer : fiber equals to 10 : 1 : 0.5-1. Large particles and lumps and the like can not exist in the S95-level grounded furnace slag, the cement is common Portland cement, and the quality of the cement conforms to relative standards; and the foaming agent is HJ foaming agent product sold in market, and belongs to the fifth generation of composite type foaming agent. The reinforcing agent is HJ composite polymer material sold in market, and contains multiple-function regulating components. The fiber is PP type polypropylene fiber. All materials after mixing and proportioning are sufficiently stirred to be uniform and then formed, wetness is kept to conduct maintenance treatment, produced air holes are closed and are not communicated, and the shape of the air holes close to spherical.
Description
Technical field
The present invention relates to a kind of foam cement, relate in particular to a kind of foam cement with performances such as good thermal insulation, insulation, sound insulation, light carryings.
Background technology
At present, the kind of the wall thermal insulating lagging material that China is common mainly contains: the foam type lagging material, the heat-insulating calcium silicate product lagging material, the silicates lagging material, the light thermal-insulating fragment of brick, according to the achievement in research of domestic and international lagging material to the performance requirement of modern novel building to material of construction, can summarize the ideal materials for wall, has good insulation, heat insulation, sound insulation sound performance, good fire line, flame retardant resistance, the sex change coefficient is little, resistance to deterioration is good, the weather resistance height, stable performance, construction is simple, with low cost, meet energy conservation and environment protection simultaneously, in production and construction process, human body and environment are not caused disadvantageous effect, and can carry out and circulate in utilization, yet existing material technology can not satisfy the demand.This has just triggered the birth of foam cement, foam cement is manufactured thermal insulation layer, be used for roof heat insulation and exterior-wall heat insulation, replace polystyrene (benzene plate) waits other lagging materials, adhesion property with unrivaled heat-insulating property and structural sheet is when also having convenient construction, environmental protection, joint, many superiority such as synergy.
Summary of the invention
Technical problem to be solved by this invention is the defective that overcomes prior art, and the foam cement that a kind of warming thermal insulation is good, lightweight is light, sound insulation vibration isolation shock resistance is superior and have good water impermeability is provided.
The technical solution adopted for the present invention to solve the technical problems is: a kind of foam cement, by cement, sand, S95 level ground slag, toughener, whipping agent, polymkeric substance, fibrous, each composition quality ratio is: cement: toughener=50:3, cement: S95 level ground slag: sand=10:4:3, cement: polymkeric substance: fiber=10:1:0.5～1.S95 level ground slag can not have macrobead and caking etc., and cement is ordinary Portland cement, and this cement quality meets relevant criterion; Whipping agent is commercially available HJ whipping agent product, belong to the 5th generation compound foaming agent.The HJ composite polymeric materials of toughener for being sold on the market contains multiple function and regulates composition.Fiber is a PP type polypropylene fibre.All material behind the mixing match stirs aftershaping, keeps the moistening maintenance processing of carrying out, and the pore after making seals not UNICOM, pore shape subglobular.
The dried surface density of aforesaid foam cement is 200kg/m3, and ultimate compression strength is 0.2Mpa, and thermal conductivity is 1W (m.K).
Aforesaid toughener is a polymer materials, and its solids content is 65-85%, and the Ph value is 7-8.
In sum, the Portland cement that sell the market in foam cement of the present invention and the prior art is compared and is had following advantage:
1, durability: the durability of foam cement will exceed more than 1,100 times than the durability of porous plastics, the intensity of foam cement reaches more than the 15MPa/c ㎡, movable walking above the people can step down in, and its life-span is very long, exposing to the weather at one's discretion in 100 decades, drench with rain can be not bad, the weathering of can not wearing out; And the intensity of porous plastics has only 0.012MPa/c ㎡, can not bear any pressure, and the life-span is very short, and the weathering of will wearing out after more than 3 years damages;
2, warming thermal insulation: it is how much not poor that the effect of heat insulation of foam cement is compared with the effect of heat insulation of porous plastics, and the thermal resistance coefficient of foam data is 0.06w/ (m﹠amp; #8226; K), with the thermal resistance coefficient 0.08w (m﹠amp of foam cement; #8226; K) differ 0.02w/ (m﹠amp; #8226; K), promptly effect of heat insulation is more or less the same; Though it is a little bit poorer a little that the effect of heat insulation of foam cement is compared with porous plastics, owing to its intensity, life-span, fire prevention, cost, easy construction or the like, occupy suitable remarkable advantages, obtained general application in developed countries such as America and Europes;
3, fire-proof high-temperature resistant: foam cement is a non-fire material, and it is not inflammable high temperature resistant, does not damage in 2 hours with baked wheaten cake continuously, can anti-1200 ℃ high temperature; And porous plastics is an inflammable material, inflammable non-refractory, and the temperature that surpasses 80 ℃ will be softened damage;
4, the toxicity feature of environmental protection: foam cement is nonpoisonous and tasteless, environmental protection; And porous plastics contains toxic substance, and these toxic substances can long-term slowly elegant the healthy of people of coming out to influence.Though foam cement itself is nonpoisonous and tasteless, but some is except the foam cement of the whipping agent manufacturing that can go bad, the foam cement of making of the animal foaming agent particularly, because of these animal foaming agent after the cement the inside has been grown the time, can rotten discharge putrescible smell, so will note not adopting those to cause rotten whipping agent to make foam cement easily; 5, lightweight: foam cement with compare and will weigh with the porous plastics of volume, but in the practical application, during particularly building materials are used, we on the contrary also for porous plastics too light have a headache the lightweight of foam cement and have the application that certain intensity just adapts to building materials on the contrary; So, if be used for the building materials aspect warming, heat insulation, fire prevention, waterproof, partition, long-lived durable, reduce cost etc., it is best still selecting foam cement for use.
