1. Preparation of p-hydroxybenzylsulfonic acid using cresol as raw material; Preparation of naphthol sulfonic acid using naphthol as raw material.
2. Add p-hydroxybenzyl sulfonic acid and naphthol sulfonic acid respectively to the condensation kettle, add excess formaldehyde, and condense at 196kPa. After the reaction is completed, add alkali to adjust the pH value to 8.0-10, cool, crystallize, filter, and dry to obtain the finished product.
This product can be managed according to general industrial chemicals. When using it, gloves and protective glasses should be worn to avoid direct contact with the skin and eyes. If it gets on the skin, rinse with water and soap. Place in a cool and dry warehouse to prevent exposure to sunlight and rain.
The dispersant 5040 is an anionic surfactant with excellent wetting and dispersion characteristics. The dispersant 5040 has low foaming property, can improve the fluidity of the coating, and has excellent performance of stabilizing the viscosity of the slurry. Mainly used for coating paper and water-soluble coating, used for dispersion of inorganic pigments and fillers such as clay, calcium carbonate, titanium dioxide/titanium dioxide, talc, etc. Foreign brands: NUOSPERSE FX ,SN-5040,HYDROPALAT 5040,XJ-5040

Biodegradable characteristics biodegradable
Water dispersible and easily soluble in water
Excellent dispersibility, low-viscosity coatings can be adjusted by adding a small amount. The stability of the slurry and the coating is better, and the viscosity of the coating and the slurry does not change.
Because the pigment can be dispersed well, the paint has no floating color and color spots.
A small amount of addition can be used to pay the wetting performance of the coating, so it does not need to be combined with other wetting agents, and a coating film with good water resistance can be obtained.
The use of dispersant 5040 can get less foaming, fast foam breaking paint, drying time is not long, can be made easy to coat paint.
Since it can be simply dissolved in water in any amount, there is no special requirement when adding.
It is suggested that the addition amount is 0.1-1.0% of the pigment and filler quality (solid component/solid component).
50KG or 200KG/barrel, this product is stable in physical properties and belongs to non-flammable and explosive products. After use, it should be sealed to prevent sundries from invading. Can adapt to the general ambient temperature (5 ~ 35%), avoid exposure to the sun, and the shelf life for storage is more than one year.
