Abstract
The invention discloses a modified polystyrene thermal insulation mortar. The modified polystyrene thermal insulation mortar is prepared from the following components through mixing: water, expanded perlite, polystyrene, cement, a water-retaining agent and fibers. The modified polystyrene thermal insulation mortar uses the expanded perlite and the polystyrene as lightweight aggregates; the polystyrene is modified through utilizing organic polymer emulsion, so that the cohesive force of the interfaces of the polystyrene and the cement is greatly improved, the physical organization structure of the cement hydration products is improved and the inner stress is released, so that the occurrence of micro cracks in the cement mortar is decreased; the water retaining agent and the fibers are added in the components, so that the plastic shrinkage resistance of the mortar can be remarkably improved, and the stress concentration at the tips of the mortar cracks can be reduced so as to prevent the further development of the micro cracks; therefore, the favorable application property and compactness of the mortar are ensured and the mortar is good in whole performance.
Description
Technical field
The present invention relates to a kind of building mortar, be specifically related to a kind of MPS thermal insulation mortar.
Background technology
EPS thermal insulation mortar is to obtain using polystyrene foam (EPS) granule as the preparation of main lightweight aggregate.Polystyrene foam particles itself is light porous, heat conductivity is low, heat insulation property is good, there is excellent hydrophobicity and
Toughness, acid and alkali-resistance chemical stability is good simultaneously, difficult degradation under natural conditions.There is a large amount of waste polystyrene foam in China, causes " white pollution ", is big public hazards of environment.Make full use of the advantage of polystyrene foam to prepare EPS heat preservation mortar for outer wall, be not only efficient solution certainly " white pollution " and provide a new way, as long as and take rational technology path, just can make the heat preservation mortar for outer wall that heat preservation and insulation is excellent.
Polystyrene foam is a kind of nonpolar light material, when using it as main lightweight aggregate preparation EPS thermal insulation mortar, if direct and cement mortar mix, then cement mortar is to its nonwetting not affinity, both interfacial adhesions are weak, cause that the construction workability of mortar is poor, it is difficult to construction.In order to improve the moistening affinity between cement mortar and polystyrene foam particles, it is necessary to EPS particle surface is modified.
Summary of the invention
Present invention aim at the deficiency for existing polystyrene insulation mortar, there is provided a kind of modified polystyrene as the lightweight aggregate of thermal insulation mortar, a kind of high insulating effect of preparation, moderate strength, the thermal insulation mortar that cohesive force is good, the technical solution adopted in the present invention is:
A kind of MPS thermal insulation mortar, it is characterised in that stirred mixed preparing by following components by mass percentage and form:
Water 30-40 part
Expanded perlite 5-15 part
Polystyrene 15-25 part
Cement 25-40 part
Water-retaining agent 0.5-0.8 part
Fiber 1-1.5 part.
Further, polystyrene is to modifiy through polymer copolymerization emulsions to form.
Further, described polystyrene making step: be 6.:3:1 by granules of polystyrene, ethylene vinyl acetate copolymer emulsion, water three compositions in weight percentage, stirring mixing.
Further, described polypropylene fibre length is 19mm-25mm.
Further, water-retaining agent is the hydroxypropyl methyl cellulose ether of 200,000 mpa.s.
The present invention provides the benefit that relative to prior art: the MPS thermal insulation mortar of the present invention, employ expanded perlite, polystyrene is in combination with as lightweight aggregate, by utilizing organic polymer emulsion MPS, substantially increase the cohesive force of polystyrene and cement interface, improving physical organization's structure of hydrolysis product of cement, alleviating internal stress, thus reducing the generation of micro-crack in cement slurry.Also added water-retaining agent, fiber in component, can significantly improve the ability of the anti-plastic shrinkage of mortar, fiber can reduce the stress of mortar crack tip and concentrate, it is prevented that the further development of microcrack.Ensure that application property and density that thermal insulation mortar is good, mortar overall performance is good.

Embodiment 1: a kind of MPS thermal insulation mortar, is stirred mixed preparing by mass percentage and forms: water: 40 parts by following components, expanded perlite: 10 parts, polystyrene 18 parts, cement: 30 parts, water-retaining agent: 0.5 part, fiber: 1.5 parts.
Embodiment 2: a kind of MPS thermal insulation mortar, is stirred mixed preparing by mass percentage and forms: water: 30 parts by following components, expanded perlite: 13 parts, emulsion modified polystyrene 20 parts, cement: 35 parts, water-retaining agent: 0.8 part, fiber: 1.2 parts.The present embodiment, by being undertaken emulsion modified by polystyrene, substantially increases the cohesive force of polystyrene and cement interface, improves physical organization's structure of hydrolysis product of cement, alleviates internal stress, thus reducing the generation of micro-crack in cement slurry.
Embodiment 3: a kind of MPS thermal insulation mortar, stirred mixed preparing by mass percentage to form by following components: water: 30 parts, expanded perlite: 13 parts, emulsion modified polystyrene 20 parts, cement: 35 parts, the hydroxypropyl methyl cellulose ether of 200000 mpa.s: 0.8 part, the polypropylene fibre of 19mm length: 1.2 parts.
Above the better embodiment of the present invention is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modifications or replacement under the premise without prejudice to spirit of the present invention, and these equivalent modification or replacement are all contained in the application claim limited range.
