Fluorine-free waterproofing agent and preparation method thereof

Abstract

The invention discloses a fluorine-free waterproofing agent and a preparation method thereof. The fluorine-free waterproofing agent comprises the following components in parts by mass: 0-90 parts of silicon resin, 0-90 parts of paraffin, 0-30 parts of acrylic resin, 0-30 parts of silicone oil, 0-30 parts of a crosslinking agent and an appropriate amount of diluent. The preparation method of the fluorine-free waterproofing agent comprises the steps of firstly adding an appropriate amount of diluent, adding silicon resin, liquid paraffin, liquid acrylic resin and silicone oil and stirring the silicon resin, the liquid paraffin, the liquid acrylic resin and the silicone oil evenly; and finally adding the crosslinking agent and stirring the crosslinking agent evenly. The fluorine-free waterproofing agent has the beneficial effects that the components of the fluorine-free waterproofing agent do not contain any fluorine and the prepared fluorine-free waterproofing agent does not contain thefluorine, so that the environmental pollution is avoided; moreover, preparation of the fluorine-free waterproofing agent is stirring at room temperature, belongs to physical mixing, and is free of high-temperature reaction or waste, so that the environmental pollution is reduced, and the preparation method is a preparation process in accordance with green production; and in addition, the fluorine-free waterproofing agent has good water-resistant effect and anti-siphon effect.

Description

technical field [0001] The invention relates to the technical field of textile auxiliaries, in particular to a fluorine-free waterproofing agent and a preparation method thereof. Background technique [0002] The composition of textile fiber water repellants has long been known in the art. The most widely used waterproofing agent is fluorine-containing waterproofing agent. Fluorine-based water repellents are usually composed of oligomers or polymers containing a large number of fluorine groups, which can endow fiber materials with good water and oil repellency. But in recent years, because the environmental and ecological problems caused by fluorine-containing compounds have attracted more and more attention, it is necessary to find a substitute that does not contain fluorine and can provide fibers with good waterproof performance. Contents of the invention [0003] The object of the present invention is to provide a fluorine-free waterproofing agent and its preparation ...
