The preparation method of PCM tin graphed sheet water-base resin, follows the steps below:
1) a part acid and alcohol collocation catalyst, antioxidant are selected, is reacted under conditions of 160-230 DEG C；
2) when acid value reaches 8-15mgKOH/g, 110-130 DEG C is cooled to, remaining raw material is added, temperature reaction controls acid value
45-55 mgKOH/g, cooling are added diluted solvent and are made.
2) in the step: acid value reaches 10mgKOH/g, and remaining raw material is added after cooling to 120 DEG C and is made.
1) dosage of the acid and alcohol that use in the step accounts for the 20-60% of respective total amount respectively.
The invention has the advantages that the present invention utilizes this special material modified polyester resin of E-10P, by surpassing in the raw material
Structure on long side chain promotes acid resistance, alkali resistance, salt fog resistance, water resistance, the processability of resin, while utilizing E-10P's
Simple function group, macromolecule structure provide large arch dam, the high molecular weight of resin, recycle BEPD(2- ethyl -2- butyl -1,3-
Propylene glycol) in two long side-chain structures, help excellent acid resistance, alkali resistance, salt fog resistance, water resistance, processability are provided.By
In the modification of the particular monomers such as E-10P, BEPD, so that this product possesses excellent acid resistance, alkali resistance, salt fog resistance, water-fast
Property, processability, large arch dam.
