To notice preferably guaranteeing that composition of the present invention does not contain the uncomfortable thing of heavy wax, abrasive material, glass fibre and other fabric substantially.

Silicone gel

Silicone gel is a kind of cross-linking agent of siloxanes fluids and silicone resin.Siloxanes fluids is defined as the flowable siloxane polymer with variable viscosity, and it can be branch or linear.In general, silicone resin is highly cross-linked silicone solids system, and it has with three functions (T) (as RSiO _1.5) or four functional units (Q) (as, SiO ₂) linked introduced of form.Do not increase single function or terminal component (M) owing to only increase by three or four functional units (as, R ₃SiO _0.5), this resin becomes more crisp.

The present invention is of paramount importance to be, owing to increased by two functional units (D) (as, R ₂SiO), make this resin deliquescing, can regard a kind of silicone gel as fully.Except list, three, four and two functional units to silicone resin and gel influential, changing organic group also can influence its performance.Term Q, tetra-and quat-are synonyms.Usually silicone resin and gel are made organic group with methyl, phenyl, vinyl and composition thereof, but do not have too many qualification.Other possible group comprises amine (monobasic, binary, ternary, quaternary, ring-type, diamines and triamine), and epoxides, ester, ether, halogen function organic matter, carboxyl etc. comprise hydrogen.

For purposes of the invention, the importance of silicone gel is that it is softer than resin, compares its degree of cross linking lower (that is, three-(T) and/or four-(Q) functional unit content are low) with silicone resin.It is higher that silicone gel of the present invention and siloxanes fluids or adhesive silicone rubber gum stock are compared its degree of cross linking.More particularly, preferred silicone gel has about 3%-30%T and/or Q functional unit, about 70%-97%D functional unit, about 0.1%-10%M functional unit; This silicone gel has about 5%-20%T and/or Q functional unit, about 80%-95%D functional unit, about 0.3%-8%M functional unit is better, preferably this silicone gel has about 5%-15%T and/or Q functional unit, about 85%-95%D functional unit, about 0.5%-5%M functional unit, wherein M is curable, available following molecular formula is represented

Preferably separate alkyl or the H of R and R ' or be selected from some other groups (but being not limited thereto) of following groups wherein: amine (monobasic, binary, ternary, quaternary, ring-type, diamines and triamine), epoxides, ester, ether, halogen function organic matter, carboxyl etc. comprise hydrogen.This polymer siloxane gel molecular amount should be greater than about 20000; Greater than about 50000; Even greater than about 100000; It is about 500000 ± 400000 that the molecular weight of this silicone gel can be higher than, even be higher than about 1000000.In theory, their molecular weight can be up to 10 ²⁰Preferred polymer siloxane of the present invention is lower than 10 ¹⁵, even be preferably lower than 10 ¹⁰Important factor is that this polymer siloxane is gel form.When T and/or Q functional unit content were high, the molecular weight of this gel was then lower.

In addition, this silicone gel must be a kind of like this form, preferably by a kind of aqueous carrier it is added on the fabric of washing; Therefore the emulsification form is very desirable, yet can not be limited to the emulsification of precast gel, and it is the best method of implementing most preferred embodiment of the present invention that silicone gel itself generates emulsion.

Can realize this point by multiple diverse ways.Two kinds of methods are arranged usually: (1) emulsion polymerization (referring to US4600436, Traver/Thimineur/zotto, issued July 15,1986, for Durable Silicone Emulsion Polish has listed this paper list of references in, 6.11 hurdles wherein particularly, 35-47); (2) emulsification of polymer, in emulsion, solidify then (referring to " siloxanes ", people such as Hardman, Encyclopedia of Polymer Science and Engineering, Vol.15, Second Edition, Pages 204-308, John Wiley and Sons, Inc., 1989, also listed this paper list of references in).People such as Harding have pointed out four kinds of curings: (1) concentrates; (2) peroxide; (3) platinum catalysis hydrosilation; (4) ultraviolet ray.These curings are known in the prior art, but must be noted that selection initiation material and reaction condition are to guarantee to obtain desired " gel ".

A kind of ad hoc approach of preparation gel is to make the emulsification of curable branch siloxane polymer earlier, then on being added to fabric before with in the gel of this polymer cure in the emulsion droplet.For example: with pH in the glass container is a kind of emulsification branch solidity amine functional siloxane (test emulsion of 9-10, provide by General Electric, No.124-7701, it is 20% emulsion of commercially available curable amine functions siloxanes GE, and vending articles are called SF1706) can generate the silicone gel of emulsification in 5-10 days 50 ℃ of heating.

This silicone gel is made by the branch solidity amine functional siloxane with following array structure:

Wherein X equals Z+2; Y is at least 3; Z is at least 1; R ', R " are C _1-20Alkyl or be selected from the amine groups that cyclammonium, polymeric amine and alkyl chain contain the alkylamine of 2-7 the carbon atom of having an appointment, wherein R ' or R " are amine groups at least; Curable amine functions siloxanes solidifies with the emulsification form by heating and/or adding alkali, to generate a kind of silicone gel of emulsification.

Preferred siloxanes is to work as: R is hydrogen or a kind of C _1-3Alkyl; R ¹Be C _1-3Alkyl; R " is the alkyl amine group that contains 2-7 the carbon atom of having an appointment in the alkyl chain; Wherein curable amine functions siloxanes solidifies with the emulsification form by heating and/or adding alkali, to generate a kind of silicone gel of emulsification.

Preferred siloxanes is to work as: R is a methyl; R ' is a methyl; R " is (CH ₂) ₃NH(CH ₂) ₂NH ₂; X is about 4; Y be about 27 and Z be about 2; Wherein this siloxane molecule amount is about 1000-2800, and the viscosity in the time of 25 ℃ is about the 5-40 centistoke; The solidity amine functional siloxane solidifies to generate a kind of silicone gel of emulsification with the emulsification form by heating and/or adding alkali.

The physical property of this system and starting polymer are different greatly.Help reducing wrinkle with the solidity amine functional siloxane, open in this former United States Patent (USP), as US4800026, coffindaffer/wong, 1989.1.24 approval; US4911852, coffindaffer/Trinh 1990.3.27 approval; US4923623, coffindaffer, the 1990.5.8 approval, all these patents have all been listed in this paper list of references, wherein a kind of polymer is added on the fabric, then by with other siloxane reactions it being solidified, what exceed greatly that we expect is, if make polymer cure, in emulsion, form gel, transmit this gel by a kind of liquid-carrier then, can reach the effect that outward appearance is improved after being easy to press and press, this is that the consumer is obvious to all.

The pH that increases emulsion can shorten the reaction time of the above-mentioned disclosed gel of preparation.For example, pH is 13 o'clock, can generate the SF1706 gel of emulsification at 6-30 hour, this depend on be added in the product before desired state of cure.Temperature is brought up to about 75 ℃ ± 15 ℃ from room temperature, also can improve curing reaction speed, and reduce the pH value curing reaction speed that will slow down, for example, pH is about at 2.5 o'clock, solidifies hardly after one month 23 ℃ of placements.Attention should keep temperature enough low so that this emulsion consistency.

In this reaction, amine in this system and alkali work the catalyst action that concentrates curing reaction, and alkali metal hydroxide is made the effectiveness of catalyst by Li ⁺＜Na ⁺＜K ⁺＜Rb ⁺＜Cs ⁺Order and increasing.It is known that many methods that do not need with amine or alkali siloxane polymer to be solidified are arranged in the prior art, some has been disclosed in Encyclopedia of Polymer Science and Engineering in these methods, Vol.15, Second Edition, Pages 204-308, John Wiley and Sons, Inc., 1989, these have all been listed in this paper list of references.

A kind of method of expression silicone gel characteristic is ²⁹Si; NMR.Even be emulsification form (having lax auxiliary agent such as Cr(acac) ₃), in above-mentioned particular range, also discern M.D.T and Q easily.
