Description
One, technical field
The present invention relates to a kind of two-component asphalt polyurethane water-proof paints, have the function of waterproof, antibacterial, mould proof, environmentally friendly etc.
Building class external wall waterproof material, it is related external wall paint for water-proof.
Two, background technology
Asphalt polyurethane water-proof paint grows up on the basis of tar polyurethane water-proof paint is by limitation use
A kind of elastic polyurethane waterproof paint, because using petroleum refining petroleum refining byproduct asphalt filling out as polyurethane waterproof material
Expect and gain the name, compared with traditional tar polyurethane water-proof paint, a kind of two-component asphalt polyurethane water-proof paint has following
Advantage：1. smell is small, since asphalt smell is smaller than coal tar, construction and solidification are front and back without niff, and environment is dirty
It contaminates small；2. pitch hydrophobicity is better than tar, the introducing of pitch can effectively improve water proofing property, the water resistance of polyurethane coating film；3.
Asphalt viscosity is larger, and when system uses powder filler, the addition of pitch simultaneously increases system viscosity after compatibility is handled, can
To prevent the sedimentation of inorganic filler to a certain extent；It is not that activity is filled out 4. not containing active group with coal tar different pitches
Material, can also be incorporated in base polyurethane prepolymer for use as and prepare single-component waterproof coating material, and active group need to be through special closing in coal tar
It just can be used for preparing single-component waterproof coating material after processing；5. the cold brittleness of pitch is good compared with tar, therefore asphalt polyurethane waterproof
Coating remains to flow when temperature is relatively low, can be with winter construction, and this point has very compared with tar polyurethane waterproofing paint
Big superiority；6. pitch introduces, it is necessary to some cosolvents and modifying agent be added, its surface tension can be improved in this way, make machine
The bubble that tool stirring generates is reduced, and film consistency is high.A kind of two-component asphalt polyurethane water-proof paint is external wall waterproof
Essential one of the good merchantable brand of coating.
Three, invention content
It is to be made of component A and B component present invention aims at a kind of two-component asphalt polyurethane water-proof paint, wherein A
Component is the NCO terminated prepolymers that polyisocyanates is synthesized with the polyethers of two functional groups or trifunctional, and B component is pitch, increases
Modeling agent, secondary solvent, calcium carbonate, Mo Ka, mould inhibitor, thixotropic agent, accelerating agent, catalyst, solubilizer mix under certain condition
It stirs evenly, makes it have the Building class external wall waterproof material of the functions such as waterproof, antibacterial, mould proof, environmentally friendly.
A kind of two-component asphalt polyurethane water-proof paint, it is characterised in that：
Combination material composition proportion is as follows：
A kind of two-component asphalt polyurethane water-proof paint, it is characterised in that：Production technology is：Two kinds of polyethers are poured into
It in reaction kettle, is dehydrated under vacuum conditions, is subsequently poured into TDI and reacts 5h or so at 85-90 DEG C, it is poly- to obtain a kind of end NCO bases
Urethane performed polymer, i.e. component A.All B component raw materials are added in reaction kettle one by one by defined sequence by formula, stirring is simultaneously
A few hours are dehydrated by set point of temperature, after cooling packaging and storage, as B component.
A kind of two-component asphalt polyurethane water-proof paint, it is characterised in that：Component A and B component mass ratio when use
It is 1:(1.5-2) selects optimal proportion.
The present invention is a kind of two-component asphalt polyurethane water-proof paint, with the functions such as waterproof, antibacterial, mould proof, environmentally friendly
Building class external wall waterproof material.
