Abstract
The invention provides a monocomponent polymer cement waterproof slurry containing slurry microcrystalline powder, which comprises the following substances by mass percentage: cement 40-50%, microcrystalline 3-7%, river sand 25-30%, filling material 10-18% and auxiliary agent 5-8%. The microcrystalline powder improves the accumulation between slurry particles, and improves compactness, impermeability, mechanical properties and endurance, thereby the slurry has advantages of excellent waterproof performance, excellent water resistance and aging resistance. The product has a strong adhesion stress, and after solidification, the product can be directly used on water-proof membrane for pasting tiles or cement plaster, etc. The base water content is not restricted, and construction can be carried out without visible water, and the water-proof membrane has a good ventilating function. The coagulation time is short, and after 4-hour construction, tiles can be pasted on the surface, thereby shortening the construction period. The product can be used by adding water and uniformly stirring, and can be conveniently coated by scraping and brushing or rolling. The product is nontoxic with environmental protection; the monocomponent powder form product can be stored at low temperature, thereby solving the problem of inconvenient storage in winter.
Description
Technical field
The invention belongs to building water-proof paint and dry-mix technical field, specifically, relate to a kind of single polymer cement water-proof slurry that contains the crystallite powder, it is applied to not have the waterproof and the negative hydraulic pressure WATER REPELLENT of vault of shrinking or shrinking very little metope, ground.
Background technology
The performance of single polymer cement water-proof slurry is determined that by its both macro and micro structure therefore, the pore structure that changes polymer cement waterproof slurry inside is to improve the key of its water resistance.The ultimate compression strength of general polymer cement water-proof slurry is higher, but folding strength and cohesive strength are lower, and Young's modulus is higher and deformability is very poor.
Along with the rise and the utilization of the development of Building technology, particularly novel wall material, more and more specialized to the waterproofing slurry performance demands, common polymer cement waterproof slurry will be difficult to satisfy building requirements; In single polymer cement water-proof slurry, add the inorganic mineral adulterant and can improve intergranular accumulation, improve compactness, impermeability, mechanical property and weather resistance, and cheap, the convenience of drawing materials, but only add the obviously fragility of modified mortar of inorganic mineral adulterant.Polymkeric substance can be filled the space in the mortar by accumulation filling effect and the sealing filming function of itself; In addition, polymkeric substance is by self organic composition and inorganic materials generation series of physical chemical reaction, can in mortar, form fine and close continuous film, thereby can improve the mechanical property and the impermeability of mortar to a certain extent, reduce fragility and water-intake rate, so, carry out compound being very important with mineral admixture and polymkeric substance.
The crystallite powder is a kind of novel inorganic mineral admixture, main chemical compositions is silicon-dioxide and aluminium sesquioxide, include certain hydroxyl, particular structure makes it have better modified effect, can obviously make the anti-folding, resistance to compression of waterproofing slurry, impervious and adhesive property mention lifting.
The waterproofing slurry overwhelming majority of domestic market sale at present is a two-pack, but the two-pack waterproofing slurry, its liquid ingredient is damaged by frost easily in transportation cold season and storage and inconvenience thereof, influences constant product quality; And single polymer cement water-proof slurry can perfectly solve this problem, and easy construction, working-yard Jia Shui stirs, can use, smeared but also roller coating or brushing but not only can scrape, construct and can directly carry out cement plaster on waterproof membrane after 4 hours, sticking brick etc. meet the user and require wish.
Summary of the invention
The present invention has overcome shortcoming of the prior art, a kind of single polymer cement water-proof slurry that contains the crystallite powder is provided, it is compound by crystallite powder and polymkeric substance, it is higher to have overcome single polymer cement water-proof slurry ultimate compression strength, but folding strength and cohesive strength are lower, and Young's modulus is higher and shortcoming that deformability is very poor, simultaneously, improve the mechanical property and the impermeability of mortar to a certain extent, reduced fragility and water-intake rate.
Also overcome existing traditional two-component polymer cement water-proof slurry simultaneously, at winter or cold district, the shortcoming that its liquid ingredient can be damaged by frost in transportation and storage, this material has excellent waterproof effect, good water tolerance and ageing resistance; Cohesive force is strong, can directly carry out sticking brick or cement plaster after the curing on waterproof membrane.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
