Purity >=94.0% of preferably polyethylene alcohol, alcoholysis degree 87.0-89.0, viscosity (23 DEG C)≤10mPas.
Preferred water reducer is naphthalene water reducer.
The liquid germicide of preferred fungicide to be effective constituent be 19.00-21.00%DBNPA.
The liquid mould inhibitor of preferably antifungal agent to be effective constituent be 0.27-0.33%MIT, 0.80-0.90%CIT, 8.40-9.20%BRONOPOL.
The invention also discloses the preparation method of the said products, comprise the steps: first polymer emulsion, defoamer, dispersion agent, sterilant, mould inhibitor to be pre-mixed, make component A; Quartz sand, silica powder, ash concrete, polyvinyl alcohol, water reducer are pre-mixed, make B component; Before using by A, B component preferably according to component A: B component: water=1:2.5:0.2 carries out used in combination.
A kind of easily painting type flexible water slurry; Carry out interworking combination by above raw material, realize the easy painting brushing effects of product by the interaction of polyvinyl alcohol and dispersion agent, water reducer, and the workability of product maintains effect.
Make viscosity B coefficent rate in product one hour little by adjustment formula water conservation system, ensure that product easy brushing performance of constructing can be maintained to one hour, ensure that the workability of product, also ensure that the waterproof effect of product, avoid product efflorescence simultaneously.
For the defect of prior art, a kind of easily painting type flexible water slurry; Make viscosity B coefficent rate in product one hour little by adjustment formula water conservation system and grading of aggregate etc., ensure that product easy brushing performance of constructing can be maintained to one hour, ensure that the workability of product, also ensure that the waterproof effect of product, avoid product efflorescence simultaneously.Easy painting type flexible water slurry of the present invention has excellent workability, resistance to settling property, bonding strength, waterproof effect and anti-cracking function.
