Description
Technical field
The present invention relates to a kind of building material technical field, more particularly to a kind of Polymer cement materials.
Background technology
Waterproof polymer mortar be using cement, fine aggregate as primary raw material, with the modified materials such as polymer and additive with
The waterproof material mixed is suitably matched, and current Polymer cement materials cohesive force and anti-permeability performance are poor.
Invention content
In order to overcome the shortcomings of background technology, the present invention provides a kind of cohesive force is strong, the preferable polymer of anti-permeability performance
Cement waterproofing mortar.
The technical solution adopted in the present invention is：A kind of Polymer cement materials are by the original of following mass parts
Material composition：Cement 38%-45%, river sand 18-35%, 80-120 mesh quartz sand 20-35%, dicalcium powder 3-12%, rubber powder 1-
6%, HEMC cellulose ether 0.01-0.09%, water-reducing agent 0.1-0.6%, antifoaming agent 0.1-0.6%, hydrophober 0.1-0.8%.
Preferably, the cement selection P.O42.5 Portland cements.
Preferably, the river sand selects 0.6mm river sands below.
Preferably, the dicalcium powder is 300-400 mesh dicalcium powders.
Preferably, the rubber powder is redispersable latex powder, using 5044 polyvinyl alcohols.
Preferably, the water-reducing agent is high-efficiency polycarboxylic acid water reducer.
Preferably, the antifoaming agent is silicone emulsion, the fatty acid ester compounded object of higher alcohols, polyoxyethylene polyoxypropylene season
Penta 4 alcohol ethers, polyoxyethylene polyoxy propyl alcohol amidogen ether, polypropylene glycerol aether, polyoxyethylene polyoxypropylene glycerin ether or poly dimethyl
Siloxanes etc. is one such.
The beneficial effects of the invention are as follows：This product is the dry powder Type of Collective object cement of dry powder Type of Collective object modified material composition
Waterproof mortar has superpower cohesive force and anti-permeability performance, is the impervious waterproof material of excellent rigidity, easy for construction, when practical
It is added into water and uniformly stirred；Cementitious material of the cement as Polymer cement materials, the bonding on the one hand improving coating are strong
Degree, another aspect cement and polymer glue powder effect, the hydrophilic anionic in active cation and rubber powder act synergistically, can be into
One step improves the water resistance of polymer, in terms of material selection, considers that the intensity of waterproof mortar and construction sexual balance, synthesis are examined
Consider, using P.O42.5 Portland cements；Graded sand selects natural river sand and tailing quartz sand, is substituted with tailing quartz sand
Natural sand produces the dry-mixed mortars product such as waterproof polymer mortar, can reduce the digging to natural sand, not only protection river and
Tremendous contribution is made in soil to environment and resources protection；Redispersable latex powder is had higher using 5044 polyvinyl alcohols
Flexibility, relatively be suitable for Polymer cement materials；Dicalcium powder acts synergistically with redispersable latex powder.In latex powder
Surfactant is attracted on powdered whiting surface, enhances its current potential, to can preferably be played in cement slurry
Diminishing, dispersion, plasticising, filling and homogenization, the compound dense micro-structure for making cement mortar of the two, can significantly reduce and secrete
Water makes pore structure also be improved；It is retained product cellulose ether HEMC, makes mortar that there is good water-retaining property and suitable operable
Time, the cement in guarantee system has abundant aquation moisture to improve the intensity of mortar, and ensures sand with reasonable time
The operating time of slurry；Auxiliary agent water-reducing agent reduces waterproof mortar water consumption, to reduce the formation of pore；Antifoaming agent reduces mortar
Internal bubbles volume reduces porosity.
