Abstract
The invention belongs to the technical field of water-seal and waterproof engineering of buildings, and in particular discloses a self-solidifying waterstop applied to construction joints and deformation joints in large-scale concrete construction engineering and a preparation method thereof. The self-solidifying waterstop adopts the technical proposal that the self-solidifying waterstop comprises a water-seal ring and a water-seal winged edge which is connected with the water-seal ring into a whole, wherein a transitional layer which consists of asphalt, a modifier, a plasticizer, a stabilizer, a tackifier and a coagulant is respectively arranged on the upper side and the lower side of the water-seal winged edge. The transitional layer in the self-solidifying waterstop contains the resin asphalt composition, and the resin asphalt is a good adhesive and can make the transitional layer and a waterstop body firmly adhered together, so that the peeling strength is high; and the transitional layer and the waterstop body react when contacting cast-in-site concrete (contacting water), and are gradually condensed and solidified into a whole. Therefore, the self-solidifying waterstop can effectively solve the problem of water leakage of cracks between the waterstop body and the concrete in the prior art.
Description
Technical field
The present invention relates to the sealing waterproofing technical field of building, specifically relate to the waterstop and preparation method thereof that condenses certainly that is applied to constuction joint, deformation joint in the large-sized concrete construction works.
Prior art
Waterstop is widely used in the sealing waterproofing in the engineerings such as water conservancy and hydropower, tunnel underground, civil air defense works, underground building, and the infiltration that employed waterstop exists in the above-mentioned concrete work, to scurry harm that water causes also be that people endeavour the problem that will solve always.By improving the quality of products, improve construction technology, take measure such as compound sealing to significantly reduce its drainage, but concrete in process of setting owing to shrink formed crack seepage problem and be not well solved for a long time.At GB 50108 " explanation of Technical code for water proof in underground engineering clause " 5.1.11 bar, the contraction that produces during concrete setting easily makes waterstop and following concrete generation slit, thereby causes deformation joint to leak.According to this situation, the waterstop in the clause in regulation top, the base plate is mounted to basin shape, helps to eliminate above-mentioned drawback.We know that the shrinkage strain of concrete component is the character decision of himself, and the clearance leakage problem that causes thus is that common waterstop self can't overcome.
Accompanying drawing 1 is common waterstop practical application schematic diagram, as seen from the figure, because 3 of the bonding surfaces of the solidification shrinkage of concrete 1 and waterstop 2 produce the crack, forms a penetrating passage 4.
Accompanying drawing 2 is self-adhering-type or compound waterstop practical application schematic diagram after improving.Anti-seepage effect makes moderate progress, but because the defective of water-proofing adhesive material 5 self can not adapt to the distortion of solidifying of concrete 1 fully, self also can ftracture in concrete process of setting forms infiltration slit 4, forms penetrating passage around the waterstop.Trace it to its cause, used water-proofing adhesive material is the mixture of adhesive and conventional waterproofing materials (GB rubber, modified bitumen, expanded rubber, caulking material), though can again can be firm with concrete bonding with water band strong bond, but self does not have deformability, and therefore employed waterstop with waterproof bond properties does not overcome the long-term creep contraction of concrete equally and tears the problem that forms clearance leakage.
The content of invention
First purpose of the present invention just provides and a kind ofly can and be the waterstop that condenses certainly of one with concrete.
It is above-mentioned from the production technology of condensing waterstop that second purpose of the present invention just provides preparation.
Realize that the technical scheme that the present invention's first purpose is proposed is:
A kind of from condensing waterstop, the sealing wing limit that includes seal ring and be connected as a single entity with it is provided with the transition zone that is made of following materials in weight portion in the side up and down on described sealing wing limit:
Pitch: 45-55,
Modifier: 9--13,
Plasticizing agent: 3--5,
Stabilizing agent: 0.8--1.2,
Coagulating agent: 20--30,
Tackifier: 7-11.
In addition, above-mentioned additional technical feature from the waterstop that condenses is:
---described plasticizing agent adopts naphthenic oil or aromatic naphtha;
---constitute described coagulating agent and adopt calcium silicates or active silica;
---described tackifier adopt coumarone indene resin, abietic resin or Petropols;
---between the thickness of described transition zone is 4-10 millimeters.
Realize the technical scheme that the present invention's second purpose is proposed, that is:
Preparing a kind of method from the waterstop that condenses proposed by the invention comprises the following steps:
The preparation of first step buffer layer material
At first pitch is joined in the agitator tank, heat then temperature is elevated to 150 ℃～170 ℃ scopes, while stirring modifier and plasticizing agent are added wherein simultaneously, stirred 2-2.5 hour, coagulating agent and tackifier are continued to stir and add successively in the back, stirred 20-40 minute, and added stabilizing agent at last and stirred 10-15 minutes, promptly get buffer layer material;
The applying of second step and waterstop
With waterstop body drawout, the surface is removed clean, the buffer layer material of gained is coated with on the surface that is contained in waterstop body one or both sides, and floating, sticking obedient barrier film, become bale packaging.
And the thickness that is coated with the transition zone that is contained in described waterstop body surface is between 4-10 millimeters.
The waterstop that condenses certainly that utilizes technology provided by the invention to produce, compared with prior art have the following advantages: the retinasphal composition among the present invention, be a kind of mixture of well being stained with, can make transition zone and firm being stained with of waterstop body be connected together, peel strength is very high.Calcium silicates composition in the prescription of the present invention simultaneously is actually the chief component of cement, touch cast-in-situ concrete after (chance water) react, progressively condensation cure is an one.So can well connect waterstop and concrete as a whole by buffer layer material of the present invention.
