Abstract
The invention discloses a cracking-resistant cement-base waterproof coating which comprises the following components in parts by weight: 46-47 parts of ordinary portland cement, 4-5 parts of silica fume, 37-39 parts of quartz sand, 3-5 parts of quartz powder, 0.02-0.05 parts of cellulose ether, 0.1-0.3 parts of flow modifier, 0.05-0.08 parts of calcium formate, 1-1.2 parts of water repellent, 8-10 parts of redispersible polymer powder, 0.38 parts of filler, and 35-40 parts of water. According to the cracking-resistant cement-base waterproof coating, contents of cement and sand in the traditional cement coating and a proportion of the redispersible polymer powder are changed, and the cracking resistance is improved. The cracking-resistant cement-base waterproof coating is combined with rigidity and flexibility, does not crack, is strong in adhesive force, good in waterproof effect, collision-resistant, and long in service life, and can be constructed on a humid base layer; the base layer is not required to be levelled; no protective layer is required to be made on a waterproof layer; the construction period is shortened; the comprehensive construction cost is lowered; and the cracking-resistant cement-base waterproof coating has the characteristics that the cracking-resistant cement-base waterproof coating is nontoxic, odorless, high- and low-temperature-resistant, green, and environment-friendly.
Description
Technical field
The present invention relates to a kind of cracking resistance cement-base waterproof coating, belong to building material technical field.
Background technology
In the basic unit that some intensity are lower, traditional way at it for joints cement concrete inside and outside earth's surface and underground or masonry, then after cement concrete solidification, carry out levelling with cement mortar, coat waterproof paint again, and then protective layer is done on waterproof paint, but traditional cement-base waterproof coating cohesive strength is lower, being easy to easily occurs to ftracture between this concrete basic unit and waterproof layer departs from, easily come off, encounter hard object product (as: common brick, ash cutter, iron and steel is first-class), also easily ftracture, come off, have a strong impact on work-ing life and waterproof effect.Waterproof layer smooth surface originally, very large hidden danger is had to the safety of workman when doing waterproof construction especially on Sloping roof, therefore occurred cracking resistance cement-base waterproof coating, cracking resistance cement-base waterproof coating refers in the sand of cement and different gradation and adds redispersible rubber powder, properties-correcting agent etc.After solidification, sand-cement slurry is become by perfect rigidity and has certain flexibility, its mechanism is that the molecular composition of material there occurs change, when polymer particles dosage is enough large, cement, sand and gap thereof are wrapped up by polymer particles completely and are filled, along with the volatilization of moisture, polymer particles is drawn close gradually, cement and redispersible rubber powder, form elastic layer between cement, sand, shows the flexibility of cement based.
The quality of cement-base waterproof coating raw materials quality, directly affects the technical performance index of mortar, therefore also has very strict requirement to the technical feature of the silt content of sand, the quality of sand and admixture.The cohesive strength of existing cement-base waterproof coating and basic unit is poor, easily ftractures, and has larger difference with the work-ing life of waterproof, and the content of cement sand and the content of rubber powder are all the keys of cracking resistance cement-base waterproof coating.
Summary of the invention
The object of the present invention is to provide cracking resistance cement-base waterproof coating, good anti-cracking performance, intensity can be had, have again good flexibility, there is the longer life-span.
The object of the invention is to be achieved through the following technical solutions: cracking resistance cement-base waterproof coating, it is made up of the component of following weight part:
Period, quartz sand effectively can improve the cracking resistance function of coating, silicon ash effectively can increase the density of coating, hydrophober makes coating have good water-proof function, redispersible rubber powder is acrylic acid, and its effect is strong adhesion, increases flexible, the volume of calcium formiate adjustable retardant, to adjust the knot solidifying time.
Described ordinary Portland cement is the silicate cement of the active mixed material containing 5 ~ 20%.
Described quartz sand particle size is 80 ~ 120 orders.
Described silica powder granular size is 300 ~ 500 orders.
The good fluidity that flow ability modifying agent can improve, makes cracking resistance cement-base waterproof coating easily construct, saves the engineering time, and flow ability modifying agent is existing common flow ability modifying agent, as AM-80, EMI100 etc.
Hydrophober has good waterproof effect, and cracking resistance cement based coating molecular surface can be allowed to form thin waterproof glued membrane, stops entering of water, adopts existing common hydrophober.
Redispersible rubber powder (acrylic acid), can have strong adhesion, flexible, the features such as good water-proof effect.
Beneficial effect of the present invention is: change cement in conventional cement base waterproof coating, the proportioning of the content of sand and the content of redispersible rubber powder, add the anti-cracking performance of cement-base waterproof coating, make cracking resistance cement-base waterproof coating firm but gentle, have soft just, rigid flexible system, do not ftracture, impact resistant, strong adhesion, good water-proof effect, long service life, life-span same with concrete, this product in operation, directly brush on concrete base layer, with brush or trowel construction 2 to 3 layers, every layer thickness is no more than 2mm, total thickness 3mm-5mm, can construct in the basic unit of humidity, basic unit does not need levelling, without the need to doing protective layer on waterproof layer, reduction of erection time, reduce comprehensive cost, have nontoxic simultaneously, tasteless, high-low temperature resistant, the features such as environmental protection, and, molding surface of the present invention is not shiny surface, but with some pitted skins, avoid to greatest extent when Sloping roof doing waterproof construction and have very large hidden danger to the safety of workman.
