Abstract
The present invention provides a waterproof agent for modifying polymer cement, which is prepared by using PS, namely polystyrene foam plastics, as a major ingredient and styrene as a solvent and using dibutyl phthalate, sodium carboxymethylcellulose, sodium dodecyl sulfate, etc. as auxiliary agents. Compared with those of the existing similar products, the compression strength resistance, the tensile strength resistance, the drying shrinkage rate, etc. are obviously better. Because the waterproof agent does not contain harmful substances, the waterproof agent conforms to the requirement for environmental protection. The waterproof agent has the advantages of low product cost and low operation cost, and can be widely used.
Description
Technical field the invention provides a kind of building chemical product, particularly a kind of polymer cement modification water-resisting agent.
Background technology cement is one of most important material of modern architecture.Limited to by cement inherent physics-chem characteristic, all cement concrete building ubiquity cracking and seepage two big major defects.For solving concrete cracking and leakage problems, at present, mainly adopt common petroleum asphalt-based material, high-polymer modified pitch sill and high polymer waterproof material.General petroleum pitch base waterproof material, though have characteristics such as cheap, that water resistance is better, its temperature sensitivity is strong, and unit elongation is little, can not adapt to the requirement of base course crack and dilatation, and material is easily aging, and work-ing life is short.The high-polymer modified pitch sill as SBS or APP modified asphalt waterproof coiled material and emulsified bitumen coating etc., has overcome the deficiency of general asphalt-based material on product performance, be doubled work-ing life, but its constructing operation is still complicated, and environmental pollution is very big.High polymer waterproof material, characteristics such as ethylene propylene rubber coiled material and polyurethane material etc., have the tensile strength height, elongation at break is big, tearing toughness is high, and resistance toheat is good, ageing resistance is good, but its cost height is difficult to wide popularization and application.
Polymer cement modification water-resisting agent is the novel high polymer water-proof material that utilizes polymer foam plastics and various auxiliary agent to be composited, it not only is superior to other water-proof material on performance, and constructing operation is very simple, and is little to environmental influence, is present state-of-the-art water-proof material.The research of polymer cement properties-correcting agent starts from the 1980s, and states such as U.S., day, Russia, moral maintain the leading position, and has formed a cover proven technique technology, and has formulated application standard.But because the material expensive that is adopted, product cost and use cost are higher, also are difficult to widespread use.China uses in the research of polymer cement properties-correcting agent and relatively lags behind, and is in introduction, digestion, imitation, improvement stage substantially, some products also occurred, as PAE, CR, PVOS, SBR polymer cement modification water-resisting agent etc.Performances such as the pressure resistance of these products, tensile strength, contract with dry rate remain further to be improved, and product cost is relative with use cost higher, has environmental pollution problem.Chinese patent application discloses a kind of " water-proofing additive of dissolved used plastics for cement " (CN1289795A), adopt waste and old plastics to form through the mixed organic solvents dissolving, though its performance is better than currently available products, cost is lower, contains the poisonous and harmful composition in its composition.
Summary of the invention purpose of the present invention just is to provide a kind of PS polymer cement modification water-resisting agent, it adopts polystyrene (PS) is main raw material, with vinylbenzene is solvent, and be equipped with multiple auxiliary agent and be made, its not only performances such as ultimate compression strength, tensile strength, contract with dry rate be greatly improved, and cost is low, and easily construction does not have any pollution.
For achieving the above object, embodiment of the present invention are: a kind of PS polymer cement modification water-resisting agent, by PS is that polystyrene foamed plastics forms through solvent and auxiliary agent mixed dissolution, it is characterized in that, solvent is a vinylbenzene, auxiliary agent comprises dibutyl phthalate, Xylo-Mucine, sodium lauryl sulphate and rosin, and each raw material weight per-cent is: polystyrene foamed plastics 40-50%, vinylbenzene 35-45%, dibutyl phthalate 6-10%, Xylo-Mucine 1-3%, sodium lauryl sulphate 0.5-1.5%, rosin 1-2%.
Be more effective realization the present invention, auxiliary agent can add ethylene glycol, tributyl phosphate, and each material component and optimum weight per-cent thereof are: polystyrene foamed plastics 45%, vinylbenzene 40%, ethylene glycol 2%, dibutyl phthalate 8%, tributyl phosphate 0.05%, Xylo-Mucine 2%, sodium lauryl sulphate 1%, rosin 1.95%.
Production method of the present invention is: polystyrene foamed plastics is smashed, put into the dissolving that fills styrene solvent and irritate, add auxiliary agent, got final product in stirring and dissolving 2-6 hour at normal temperatures.
For verifying every performance of the present invention, the present invention detects its every performance.Inspection shows that every performance index of the present invention not only all reach or arrive and surpass national JC494-92 standard, and obviously are better than other like product.The present invention can adopt waste old polystyrene foamed plastic, with low cost, its composition does not contain any hazardous and noxious substances, compliance with environmental protection requirements, and using method is simple, only needs to do conventional the stirring with the cement sandstone according to a certain ratio and gets final product, to reducing construction link, shorten construction period, reducing construction cost has direct significance.
Embodiment the invention provides three embodiment, and the component of respectively making of each embodiment sees the following form:
| Component | Embodiment 1 | Embodiment 2 | Embodiment 3 |
| PS(kg) | 50 | 45 | 40 |
| Vinylbenzene (kg) | 35 | 40 | 45 |
| Ethylene glycol (kg) | 2 | 2 | |
| Butyl phthalate (kg) | 10 | 8 | 7.5 |
| Tributyl phosphate (kg) | 0.05 | ||
| Cellulose sodium carboxymethyl (kg) | 1.5 | 2 | 3 |
| Sodium lauryl sulphate (kg) | 0.5 | 1 | 1.5 |
| Rosin (kg) | 1 | 1.95 | 3 |
The production method of the foregoing description is identical, at first polystyrene foamed plastics is smashed, and takes by weighing each component in proportion, vinylbenzene is injected dissolving vessel, pour polystyrene foamed plastics into, add auxiliary agent, stirring and dissolving is 3 hours at normal temperatures, detects bottled dispatching from the factory then.
