Abstract
The invention provides an innoxious environment-friendly solvent waterproof material of bridge floor, which can be painted on clean and dry cement bridge floors by a special painting spraying equipment in a certain of dosage and a layer of waterproof film with compact structure can be formed after nature solidification. The heat asphalt mix can be directly coated on the bridge floors and the work can be finished after rolling by a common road roller. The innoxious environment-friendly solvent waterproof material of bridge floor has the advantages of strong adhesiveness, good waterproof performance as well as good high temperature property and good low temperature property.
Description
One, technical field
The invention belongs to field of waterproof materials, particularly a kind of solvent type bridge floor water-proofing material and preparation method thereof.
Two, background technology
Prior art: along with China's Freeway Development, the quantity of highway bridge also constantly increases, deck paving is progressively transformed to composite pavement by cement concrete bridge deck at present, and therefore, combined type deck paving problem has caused domestic colleague's extensive concern.Domestic and international many research and engineering practice show that the combined type deck paving has good road-ability and continuity, and become the main flow of current and even later deck paving development gradually.According to the working conditions of deck paving, how to improve interlayer water resistance, adhesiveproperties and the shear behavior of deck paving, be the gordian technique of combined type deck paving.But, the present domestic related specifications that also do not form at present.Waterproof bridge floor material is of a great variety, does not have unified standard, causes China's deck paving quality uneven.
In the past, some bridge is water layer in the air on surface layer is mated formation, main rely on that draining is come on slope and weep pipe in length and breadth, though some bridge floor has also been done waterproof layer, but it can't meet the quality requirement, and causes that the bridge surface layer occurs that infiltration, the pull-up of mating formation fall, cement concrete alkali-aggregate reaction, steel bar corrosion, steel plate corrosion and cause that bridge damages.In order to protect the bridge structures to exempt from the infiltration etch, improve the weather resistance of bridge, increase the service life, when the designs of road and bridge and construction, must pay much attention to the waterproof problem of road and bridge.
Abroad, country such as U.S. clearly regulation city and highway bridge must be provided with waterproof layer.China begins to pay attention to the problem that bridge suffers the rainwater etch from the eighties in 20th century, and has carried out many monographic studies with regard to the bridge structure waterproof technique.Think the subject matter that the bridge waterproof exists by researching and analysing: the one, the Bridge Design problem showing that mainly unreasonable the and stressed weak link of the design place of mating formation do not do WATER REPELLENT and the unreasonable problem that causes of bridge structure waterproofing design; The 2nd, the water-proof material problem mainly is the water-proof material that lacks the bridge special use; The 3rd, on the construction link, the waterproof construction quality does not form unified working specification and standard for acceptance as yet, lacks the bridge construction waterproof construction troop of specialty.
Domestic in the bridge of newly-built or transformation, the way of waterproofing work is to add waterproof layer between the skeleton construction of bridge or steel construction and asphalt concrete pavement layer.Present domestic water-proof material mainly contains road and bridge special-purpose water-proof coiled material, waterproof paint, waterproof and sealing material etc. based on flexible waterproof material.Waterproof roll high thermal resistance, impermeability, ageing resistance, anti-ly press against brokenly, high temperature shearing resistance, anti-low-temperature cracking all be better than waterproof paint, but easily play drum during the coiled material construction and cause slip; Waterproof paint has characteristics such as easy construction, cost is low, the road pavement planeness is less demanding, cohesiveness is good, but tensile strength that most coating is filmed and unit elongation are lower, and relatively poor to the adaptability of bridge deformation, rigidity is filmed then poorer.
Publication number is that the patent of invention of CN2606106 once disclosed a kind of autohension modified asphalt bridge deck water-proof coiled material; it is by tire basic unit; top self-adhesion waterproof layer; bottom self-adhesion waterproof layer; sealing coat and protective layer are formed; it is characterized in that; described tire basic unit is by strong unit elongation; cohesive force and Nai Gao; cryogenic material is formed; and be provided with described top self-adhesion waterproof layer and described bottom self-adhesion waterproof layer in its both sides; described sealing coat is arranged at the self-adhesion waterproof layer outside, bottom; and be coated with release agent in the one side that contacts with described bottom self-adhesion waterproof layer at least; described protective layer is made up of the film of non-refractory, is arranged at the self-adhesion waterproof layer outside, described top.But in practical engineering application, this waterproof roll is difficult to fit tightly with rough decking, have bigger constructional deficiency, and the part is punctured easily in construction process.These defectives have had a strong impact on its waterproof action and adhesive effect, therefore use not extensive.
Three, summary of the invention
The present invention is directed to above-mentioned technical problem, good non-toxic environment protective solvent type bridge floor water-proofing material of a kind of waterproof and adhesiveproperties and preparation method thereof is provided.
Technical solution of the present invention is: a kind of non-toxic environment protective solvent type bridge floor water-proofing material, and matrix pitch, organic solvent, rubber modifier, tackifier, photostabilizer and softening agent, the composition mass component is:
100 parts of matrix pitches
10～30 parts of rubber modifiers
120～200 parts of organic solvents
20～100 parts of tackifier
3～7 parts of photostabilizers
2～10 parts in softening agent
Matrix pitch is common heavy friendship 70# or 90# pitch or 110# heavy-duty road asphalt.Rubber modifier is natural rubber or thermoplasticity synthetic rubber.Synthetic rubber is the styrene-butadiene-styrene block polymer.Organic solvent is that naphthenic hydrocarbon, aromatic hydrocarbon, ketone or ethers organic compound tackifier are petroleum resin, coumarone indene resin, terpine resin or natural Gum Rosin.Photostabilizer is a salol.Softening agent is a dimethyl phthalate.A kind of method for preparing non-toxic environment protective solvent type bridge floor water-proofing material, preparation process is: to be sequentially added into rubber modifier, tackifier and softening agent in the organic solvent in the stirring of 50～100r/min rotating speed, stirred 10～30 minutes with same rotating speed after reinforced the finishing in reactor; In reactor, add 140～170 ℃ of matrix pitches and photostabilizer successively, continue to stir 15～30 minutes, naturally cool to room temperature with 50～100r/min rotating speed; Open reactor, product is packed, promptly formed solvent type bridge floor water-proofing material.
Beneficial effect: non-toxic environment protective solvent type bridge floor water-proofing material of the present invention has advantages such as bonding strength height, water resistance is good, high temperature performance is good.Adopt specific paint spay-coating equipment to be sprayed at totally, on the exsiccant cement decking, after the spontaneous curing, promptly to have formed the waterproof membrane of one deck compact structure according to certain consumption.Then hot asphalt can directly be paved on the decking that covered this tunic by compound, use street roller commonly used to roll again and get final product.
