Description

{WATER-BASED SURFACE TREATMENT AGENT}

The present invention relates to an aqueous surface treating agent, particularly a water-repellent emulsion and an antifouling agent.

Conventionally, a fluorine-containing water and oil repellent agent containing a fluorine compound is known. This water and oil repellent agent exhibits good water and oil repellency when treated with a substrate such as a textile product.

From a recent study [EPA report "PRELIMINARY RISK ASSESSMENT OF THE DEVELOPMENTAL TOXICITY ASSOCIATED WITH EXPOSURE TO PERFLUOROOCTANOIC ACID AND ITS SALTS" (http://www.epa.gov/opptintr/pfoa/pfoara.pdf)], Concerns about environmental burden on PFOA (perfluorooctanoic acid), a type of roalkyl compound, became clear and on April 14, 2003, the US Environmental Protection Agency (EPA) announced that it would strengthen scientific research on PFOA.

The Federal Register (FR Vol. 68, No. 73 / April 16, 2003 [FRL-2303-8], http://www.epa.gov/opptintr/pfoa/pfoafr.pdf) and EPA Environmental News FOR RELEASE : MONDAY APRIL 14, 2003 EPA INTENSIFIES SCIENTIFIC INVESTIGATION OF A CHEMICAL PROCESSING AID (http://www.epa.gov/opptintr/pfoa/pfoaprs.pdf) or EPA OPPT FACT SHEET April 14, 2003 (http: // www. epa.gov/opptintr/pfoa/pfoafacts.pdf) is known to be capable of producing PFOA by degradation or metabolism of telomers (telomeres means long chain fluoroalkyl groups). It has also been disclosed that telomers are used in many products such as water-repellent, oil-repellent, antifouling-imparted foam extinguishing agents, care products, cleaning products, carpets, textiles, paper and leather. There is a concern that a fluorine-containing compound may accumulate in the environment.

The fluorine-containing water- and oil-repellent agent containing a fluorine-containing polymer must be subjected to heat treatment at a high temperature (for example, 100 ° C or higher) after adhering to a base material such as a fiber product in order to develop water and oil repellency. The heat treatment at high temperature requires high energy.

Further, the fluorine-containing polymer is expensive.

Therefore, there is a case where it is desired not to use the fluorine-containing polymer or to reduce the amount of the fluorine-containing polymer.

Japanese Patent Application Laid-Open No. 2006-328624 discloses a water repellent agent comprising a non-fluorinated polymer having a (meth) acrylate ester having a carbon number of 12 or more in the ester portion as a monomer unit, wherein the constituent ratio of the (meth) Is 80 to 100% by mass based on the total amount of the monomer units constituting the water repellent agent.

However, this water repellent agent is poor in water and oil repellency.

Japanese Patent Application Laid-Open No. 2006-328624
