Abstract
The utility model discloses a composite anti-penetrating mud felt, which relates to a base body. The shape (solid and liquid) of the base body can be converted. The base body is converted into a thick paste form from a solid by means of water suction to generate expansive force to clog leakage. An upper supporting layer (1) and a lower supporting layer (3) on the anti-penetrating mud felt uses modified starch to serve as adhesive which is coated on non-woven fabric or a piece of paper with a rough surface. After the adhesive is dried, the utility model is rolled into a (paper) barrel for standby. An anti-penetrating layer (2) is modulated into a moistening object by active bentonite, bulking starch, papermaking fiber, antimildew agent, etc. according to a definite proportion, is arranged between the upper supporting layer (1) and the lower supporting layer (3), and is shaped by mixing and pressing.
Description
The utility model relates to a kind of compound antiseepage mud felt, belongs to the building materials industry field, particularly relates to the antiseepage building material product of solid, liquid (paste) possibility of reversal.
Because concrete and the early stage drying shrinkage of mortar, the existence of later stage shrinkage and pore causes concrete roof and underground construction how much to have seepage.Along with the technological progress of building material industry, Yan Zhi waterproof material kind is a lot of in recent years, from the form of product: the sheet material of moulding is arranged, solid (powdery), liquid (water-based, oiliness are filmed) and ointment shape of site operation or the like are arranged.Raw material from the product use: the major product of contemporary waterproofing is the compound based on macromolecular compound, all are new products of developing round water resistance selection (as rubber, plastics, pitch etc.), also have at concrete or in mortar to add expansion agent, overcome the pore seepage.More than all waterproof materials all be to be the waterproof material of purpose with waterproof, above product respectively has pluses and minuses, ubiquitous is that raw and auxiliary material costs an arm and a leg, the source of goods is in great shortage, as polyvinyl chloride (PVC product), the material modified SBS that the polymer modified asphalt malthoid is used and APP or the like cause production marketing to be subjected to certain restriction, also need continue the development of new products.
The purpose of this utility model is that a kind of suction of design, dewatering are good, imbibition power is strong, the good matrix of dehydration nerve, this matrix can finely cooperate with cementing agent, fortifying fibre, be made into compound antiseepage mud felt, this antiseepage mud felt when matrix absorption effusion becomes thick shape lotion by solid, produces expansion force and stops up seepage in concrete or mortar close certain space under the condition.
The purpose of this utility model is achieved in that the compound antiseepage mud felt of solid, liquid body possibility of reversal, and technical characterictic is to be provided with one deck impervious barrier (2) between upper supporting layer (1) and the lower supporting layer (3).The surface applied of upper supporting layer (1) and lower supporting layer (3) oxidized starch and is made adhesive layer.Impervious barrier (2) is by active swelling scholar, expanded starch and paper-making fibre and mould inhibitor etc., is modulated into moistening shape by a certain percentage, places mixed pressure moulding between upper supporting layer (1) and the lower supporting layer (3).
Take the utility model of above measure, flat appearance, the soft tubular that is rolled into of matter is convenient to the sticking method construction in packed and transported and shop.The active bentonite of described impervious barrier (2), expansion multiple＞20 smectite contents＞70%.Expanded starch can be along with inhaling, dewater the inversion of solid, liquid body as the bonding adhesive of swell soil and reinforcing fibre.
The utility model is described in further detail below to reach embodiment more in conjunction with the accompanying drawings.
Accompanying drawing 1 is the cut-away view of compound antiseepage mud felt.
Embodiment: make a kind of compound antiseepage mud felt, supporting layer (1), (3) are made coating binder with nonwoven through oxidized starch, drying for standby.The soil property filler of impervious barrier (2): matrix is selected Binyang County, Guangxi swell soil (calcium base) for use, and raw ore smectite content 68%, raw ore stir through the water logging bubble montmorillonite is separated with impurity (gravel), improve smectite content＞70%, with the H of 20% concentration
2SO
4Activate 3 hours, add the inorganic potassium salt (K of raw ore weight 0.5% simultaneously
+), adding water fully stirs, through precipitated and separated, supernatant and the recycling of thin mud, the excess filtration drying becomes wetting shape active bentonite (matrix), add an amount of alkaline pulp fiber, mould inhibitor (penta sodium pentachlorophenate), and the expanded starch of adding matrix (weight meter) 3%, after fully hybrid modulation becomes wetting shape, place between upper supporting layer (1) and the lower supporting layer (3) through the mixed pressure moulding, thickness 4-6mm, dry product.
Claims (3)
1, a kind of compound antiseepage mud felt between the upper supporting layer (1) and lower supporting layer (3) that it is characterized in that being made of wool spinning cloth or cartridge paper, is provided with one deck impervious barrier (2).
2, antiseepage mud felt according to claim 1 is characterized in that the surface applied of upper supporting layer (1) and lower supporting layer (3) the oxidized starch adhesive layer.
3, antiseepage mud felt according to claim 1, it is characterized in that mixing in the impervious barrier (2) active bentonite is arranged, expanded starch and paper-making fibre.
