Description
Technical field
The invention belongs to field of waterproof materials, and in particular to a kind of ground brickwork joint waterproof material and its preparation technology.
Background technology
Certain gap can be all produced after floor tile finishing, gap must carry out waterproof for a long time, only waterproof is done
Gap wiping will not leak after good.Water-repellent paint can be divided into 3 kinds according to development history journey at present, and the first water-repellent paint is ancient
Pitch, second is exactly modified pitch, and the third is exactly common high-molecular coating at present.High molecular water-proof paint has reaction
Type and emulsion-type and solvent-borne type, wherein being preferred option with solvent-borne type.Execution conditions are not high, and effect is good.And inorganic grouting material because
The features such as its is economic and environment-friendly, the favor of people is constantly subjected to, but it is present that concrete castability is poor, setting time is long, pliability is poor, body
Product shrinks the shortcomings of big, equally limits the application and development of inorganic grouting material.Prepare Organic-inorganic composite injection material
Expected into it is presently the most important the problem of.
Patent CN103045067 discloses a kind of cement concrete bridge deck waterproof material and preparation method thereof, described anti-
Water material is by isocyanates and Pluronic polyols generation carbamate, adds common heavy traffic paving asphalt and be catalyzed through tertiary amines
Agent, composite anti-foaming agent and ethyl acetate is composite modified forms；Alleviate the bridge structure caused by infiltration to destroy, delay highway
Bridge service life, but it is mainly used in bridge deck water-proof, it is impossible to stitch with being directly used as with waterproof material, and it is existing relevant open
Patent in never have mention dedicated for ground seam waterproof material.The invention provides a kind of ground brickwork joint waterproof material and its
Preparation technology, because the part-structure cell surface for forming pitch powder is smaller with hydroxyl, imino group isoreactivity group, particle diameter
More be advantageous to these groups and the cross-linking reaction of-NCO group, so that product properties increases, this pitch-cementitious composite material
Material is formed by emulsified asphalt and cement composition, and this is high molecular polymer and the inierpeneirating network structure of inorganic material, and it has
There is the intensity of cement Seed harvest, and because the intervention of asphalt emulsion adds the diffusivity of slurries, there is excellent water resistance.
The content of the invention
It is an object of the invention to provide a kind of ground brickwork joint waterproof material and its preparation technology, this pitch-cement are multiple
Condensation material is formed by emulsified asphalt and cement composition, and this is high molecular polymer and the inierpeneirating network structure of inorganic material,
It has the intensity of cement Seed harvest, and because the intervention of asphalt emulsion adds the diffusivity of slurries, has good waterproof
Property.
In order to achieve the above object, the technical solution adopted by the present invention is：A kind of ground brickwork joint waterproof material, including it is following
Parts by weight material：
Also include, 1-8% accelerator calcium chloride and 0.5-1% polycarboxylic acid water reducing agent；
Wherein, emulsifying agent BH-Z1；Softening agent is castor oil.
The preparation technology of this ground brickwork joint waterproof material, step include：
1) raw material is weighed in proportion；
2) asphalt emulsification：Distilled water and emulsifying agent are added in pitch, pitch heating and melting is mixed with ultrasonic emulsification
Close uniform, addition neoprene latex and softening agent mixing in pitch after emulsification；
3) preparation of pitch-cement composite material：The pitch obtained in step 2) is mixed with sulphate aluminium cement, added
Enter B943 defoamers, accelerator and water reducer mixing, stirring 30-60min in the case where rotating speed is 1000-2000r/min is dripped
Green grass or young crops-cementitious composite waterproof material.
Preferably, the coal tar pitch crosses 200 mesh sieves.
Preferably, the specific surface area of the sulphate aluminium cement is 600-800m2/Kg。
Preferably, the calcium chloride is pure to analyze.
The beneficial effects of the invention are as follows：
After 1. the emulsification of pitch dissolves pitch heating, by the effect of mechanical shearing, make tiny bitumen particle point
It is dispersed in the aqueous solution of emulsifying agent, forms that the particle diameter of oil-in-water asphalt emulsion pitch powder is smaller, and its surface area is bigger, point
Divergence is bigger, bigger with the contact surface of matrix polyurethane material, and the abundant infiltration being more beneficial between the two combines and stress point
Dissipate.Further, since the part-structure cell surface of composition pitch powder is smaller with hydroxyl, imino group isoreactivity group, particle diameter
More be advantageous to these groups and the cross-linking reaction of-NCO group, so that product properties increases.
2. modified sulphate aluminium cement specific surface area is close to Novel super-thin cement.Such a modified novel concrete
Itself it is a kind of preferably high performance water proof material, it has the excellent permeability similar to organic chemistry grouting liquid, has more
High intensity and durability, and there is the feature of environmental protection, it is pollution-free to surrounding environment, it is high anti-to be provided simultaneously with quick hardening sulphoaluminate cement
Ooze the features such as performance, water absorption rate are low and wear-resisting.
