Fluorine Silicone Product Persist

So far, both fluorine compounds and silicone compounds have been used as release agents for the molding of various rubbers and resins. For example, Fluorine Silicone Product as a silicone compound, there is known to be pure silicone oil, a variety of modified silicone oil, silicone resin, etc., as fluorine compounds, known to contain the whole fluorine alkyl phosphate compounds. In addition, silicone compounds and fluorine compounds can be mixed to improve the demoulding.

Traditionally used fluorine compounds are mainly compounds with more than 8 carbon atoms in the fluorine alkyl chain. Recently, it is feared that Fluorine Silicone Product the fluorine compounds with at least 8 carbon atoms in the whole fluorine alkyl Fluorine Silicone Product chain are persistent in the environment due to their difficult degradation and high accumulation. As a result, an attempt was made to find a fluorine compound containing a short fluorine chain based on a lower environmental durability.

Also known is the fluorine-silicon compound, Fluorine Silicone Product which has both a portion of the silicone and fluorine in the molecule. Patent Document 3 describes a fluorine-silicone compound, which is an ingredient in a composition that forms a curable silicone membrane that is water-resistant and oily, although patent document 3 does not describe the use or release of a separate said fluorine-silicone compound.

The invention provides a release agent composition for a fluorine-silicone compound containing type (i). The composition herein represents a single product or a mixture of at least two products.

W Ri is preferably CuO, preferably Cw2, with substituted or not substituted radicals, or preferably C6.2. , preferably C 2, with substituents or aryl which do not have substituents. The alkyl can replace halogen atoms such as chlorine atoms. The aryl radicals may replace halogen atoms such as chlorine atoms, or alkyl C-H such as methyl. Examples of W Kong include alkyl groups that do not have substituents such as methyl, Ethyl, propyl, hexyl, and 12 alkyl;

5 alkyl groups having substituent, such as phenyl and naphthalene bases, aryl radicals that do not have substituents, such as 4-chlorophenyl and 2-methylphenyl aryl. Fluorine Silicone Product Among them, the preferred base of the base, in particular, does not have substituents, preferably methyl.

However, R3 and R1q can be Rf-x or Z-Y, where x and Y are the same or different

The two valence organic group, RF is CL6 fluorine Huan base, Z is contains the hydrolytic site of the methyl silicon Huan base. X and Y are two valence organic groups preferably D.20 and preferably D. U. Examples of the Bivalent organic groups include (preferably CM2) alkyl, such as diethyl,Fluorine Silicone Product sub-propyl, methyl ethyl, Yassinki, and sub-decyl, and (preferably Cw2) alkyl oxygen, such as methylene, methylene, methylene, propylene oxide, methylene and ethyl oxygen, Adinki, etc. In addition, X can be (preferably CW2) alkyl amide, such as methylene amide, propylene

Amino amide and N-decyl amide. Preferably, x and Y are-(CH2). where R is an integer of 2 20, especially an integer of 2 12.

RF is a fluorine alkyl, preferably with 1 6 carbon atoms, such as 1 5 carbon atoms, especially 1 4 carbon atoms of the whole fluorine alkyl. Examples of RF are trifluoromethyl, trifluoromethyl, Tetrafluoroethoxy, 2-three trifluoromethyl-Total fluorine ethyl, total fluorine butyl, total fluorine amyl and whole fluorine. Preferably five fluorine ethyl.

Z is a silicon alkyl containing a hydrolytic site that can have 1 60 carbon atoms. Z can be-(r ") q (x,) 3 (R") is a 1 20 carbon atom, preferably 1 4 carbon atoms of the base, Fluorine Silicone Product X, is a hydrolytic site, q is 0, 1 or 2. In addition, z can be-(SI (RU) 20VSi (RH) Q (x,) 3 (R) is a base with L 20 carbon atoms, preferably 1 4 carbon atoms, X, which is the hydrolytic site, R is L 200). RU can be methyl, ethyl, propyl, base or 12 alkyl, the most preferred methyl. Examples of x as hydrolytic sites include halogens, such as chlorine and bromine; epoxy (preferably with 1 12 carbon atoms), such as Methoxy, Ethoxy, propyl, methoxy ethoxy and butyl oxygen base; acyl oxygen (preferably with 1 12 carbon atoms), such as acetyl oxygen, propyl and benzoyl oxygen, chain of allyl, Fluorine Silicone Product such as Isopropyl and isobutene; sub-amino oxime group (preferably with 1 12 carbon atoms), such as two methyl ketone oxime, methyl ethyl ketone oxime, diethyl oxime and Cyclohexyl cyclohexyl oxime ; Amino (preferably with 1 12 carbon atoms, substituted for at least one alkyl), such as ethyl Amino, diethyl and two-amino; Fluorine Silicone Product amide (preferably with 1 12 carbon atoms), such as N-acetyl amino and N-ethyl acetyl amino, and the amine oxygen base with substituent (preferably with 1 12 carbon atoms, substituting at least one alkyl with 1 4 carbon atoms preferably), such as two methyl amine oxygen and two ethoxy。
