Abstract

The invention relates to a hydrophobic waterproof emulsion and a preparation method thereof. The hydrophobic waterproof emulsion is prepared from the following raw materials in parts by weight: 10-26 parts of acrylic resin, 5-11 parts of beewax, 7-8 parts of an emulsifier, 3-6 parts of palmitic acid, 0.5-1 part of a defoaming agent, 0.1-0.2 part of a preservative and 40-60 parts of water. The hydrophobic waterproof emulsion is scientific and reasonable in component proportion and free of alkylphenol, and the system is low in odor and environmentally friendly. After testing, centrifugation, standing and lotus leaf hydrophobic effects are excellent, and the highest water resistance time can reach more than 7 days. The emulsion is high in stability, can be coated by a coating machine, can also be dip-coated and sprayed, and is suitable for producing corrugated paper, kraft paper, cardboard paper and the like with high hydrophobic and waterproof requirements; the process is simple and easy to control, and large-scale production is facilitated.

Description

technical field [0001] The invention belongs to the field of chemical additives, and in particular relates to a hydrophobic and waterproof emulsion and a preparation method thereof. Background technique [0002] Due to its diverse physical and chemical properties, hydrophobic and waterproof emulsions have been widely and importantly used in many important fields such as water-based coatings, construction, and papermaking, and new application paths have been continuously developed. [0003] However, most manufacturers currently use polyurethane emulsion, which not only has no hydrophobic lotus leaf effect, but also has poor system stability, and the water resistance effect cannot be maintained for a long time. In addition, most of the emulsifiers used are alkylphenols, which are harmful to the environment. [0004] Therefore based on this, propose technical scheme of the present invention. Contents of the invention [0005] In order to solve the problems in the prior art, ...
