The invention discloses an environment-friendly
fluoride-free
waterproofing agent as well as a preparation method and application thereof. The
waterproofing agent is mainly prepared from the followingraw materials in parts by weight:
silicon-carbon compound
copolymer waterproofing agent
mother liquor, a stabilizer, an
acidity regulator and water, wherein the
silicon-carbon compound
copolymer waterproofing agent
mother liquor is mainly formed by mixing a methyl
hydrogen-containing
siloxane emulsion, a hydroxyl
silane emulsion and a carboxyl
silane emulsion, and the stabilizer is mainly formedby mixing
ethanolamine and a cross-linking agent. The
fluoride-free waterproofing agent capable of replacing a traditional
fluorine-containing waterproof agent is prepared. When the
fluoride-free waterproofing agent is added into material primary pulp for preparing a
meal box, a finished product is
environmentally friendly, healthy and excellent in waterproof performance, a
plant fiber degradableenvironment-friendly packaging
meal box prepared through the optimized preparation technology is economical, safe and
environmentally friendly, the
meal box is outstanding in waterproof performance, mechanical performance, sealing performance and hot water permeability resistance, meanwhile, the degradable performance is excellent, and the environmental
pollution pressure caused by a
plastic packaging material can be relieved.
