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

A kind of cracking resistance cement-base waterproof coating
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 lower basic unit of some intensity; traditional way is the inside and outside joints cement concrete that is used for earth's surface and underground or masonry at it; then after cement concrete solidifies; carry out levelling with cement mortar; coat again waterproof paint; and then do protective layer at waterproof paint; but traditional cement-base waterproof coating cohesive strength is lower; be easy to easily cracking disengaging between this concrete basic unit and waterproof layer; easily come off; run into hard article (as: common brick; the ash cutter; iron and steel is first-class), also ftracture easily; come off, have a strong impact on work-ing life and waterproof effect.Waterproof layer smooth surface originally, safety to the workman has very large hidden danger when tiltedly roofing is done waterproof construction especially, therefore the cracking resistance cement-base waterproof coating occurred, the cracking resistance cement-base waterproof coating refers to adding redispersible rubber powder, properties-correcting agent etc. in the sand of cement and different gradation.After solidifying, sand-cement slurry is become by perfect rigidity and has certain flexibility, its mechanism is that variation has occured in the molecular composition of material, when the polymer particles dosage was enough large, cement, sand and gap thereof were aggregated thing particulate parcel fully and fill, along with the volatilization of moisture, polymer particles is drawn close gradually, cement and redispersible rubber powder form elastic layer between cement, the sand, show the flexibility of cement based.
The quality of cement-base waterproof coating raw materials quality directly affects the technical performance index of mortar, so the silt content of sand, the quality of sand and the technical feature of admixture are also had very strict requirement.The cohesive strength of existing cement-base waterproof coating and basic unit is relatively poor, and easy cracking has larger difference with work-ing life of waterproof, and the content of cement sand and the content of rubber powder all are the keys of cracking resistance cement-base waterproof coating.
Summary of the invention
The object of the present invention is to provide the cracking resistance cement-base waterproof coating, can have preferably anti-cracking performance, intensity, good flexibility is arranged again, have the long life-span.
The objective of the invention is to be achieved through the following technical solutions: the cracking resistance cement-base waterproof coating, it is comprised of the component of following weight part:
During this time, the cracking resistance function of quartz sand energy Effective Raise coating, the silicon ash can effectively increase the density of coating, hydrophober is so that coating has preferably water-proof function, the redispersible rubber powder is acrylic acid, and its effect is strong adhesion, increases flexible, the volume of calcium formiate capable of regulating retardant is to adjust the solidifying time of knot.
Described ordinary Portland cement is the silicate cement that contains 5~20% active mixed material.
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 is constructed the cracking resistance cement-base waterproof coating easily, has saved the engineering time, and flow ability modifying agent is existing common flow ability modifying agent, all can such as AM-80, EMI100 etc.
Hydrophober has good waterproof effect, can allow cracking resistance cement based coating molecular surface form thin waterproof glued membrane, stops entering of water, adopts existing common hydrophober.
Redispersible rubber powder (acrylic acid) can have the characteristics such as strong adhesion, flexible, good water-proof effect.
Beneficial effect of the present invention is: changed cement in traditional cement-base waterproof coating; the proportioning of the content of the content of sand and redispersible rubber powder; increased the anti-cracking performance of cement-base waterproof coating; make the cracking resistance cement-base waterproof coating firm but gentle; have gentle just; hard and soft combination; do not ftracture; anti-collision; strong adhesion; good water-proof effect; long service life, with the same life-span of concrete, this product is in operating process; directly brush at concrete base layer; construct 2 to 3 layers with brush or trowel, 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, need not to do protective layer on the waterproof layer, the reduction of erection time; reduce comprehensive cost; have simultaneously nontoxic; tasteless; high-low temperature resistant; the characteristics such as environmental protection, and molding surface of the present invention is not to be shiny surface; but with some pitted skins, the safety to the workman when having avoided to greatest extent doing waterproof construction on the oblique roofing has very large hidden danger.
