Description

I

A RICINOLEATE URETHANE POLYOL AND A
2 CHLORINATED POLYVINYL CHLORIDE
3 BACKGROUND OF Lowe INVENTION
-
4 Ricinoleate urethane polyols are well known in the art S for use in the formulation of adhesives and coatings as 6 plasticizers, pigment dispersing agents and tackifiers as 7 well as a reactive ingredient.
8 Ricinoleate urethane polyols themselves vary in consistency 9 from high viscosity oils to greases and, while they have some tack, they lack cohesive strength. Thus, they are not employed 11 alone as pressure sensitive adhesives or contact cement nor 12 do they impart cohesive strength to adhesives when used as 13 tackifiers.
14 Two-package urethane adhesives which cure by the reaction of the hydroxyl groups of the ricinoleate urethane polyol 16 with an isocyanate are strong adhesives when cured but exhibit 17 very little green strength. "Green strength" as used herein 18 means the ability to hold two surfaces together when first 19 contacted and before the adhesive develops its ultimate bonding properties when fully cured.
21 The degree of green strength exhibited by an adhesive 22 is vital to many applications. High green strength tends to 25l/

.

Lo 1 prevent wrinkling and slippage of films during lamination.
2 In panel assembly and packaging, it permits Easter handling 3 and wrapping. When Jan adhesive is applied to a vertical surface, 4 a sufficiently high green strength prevents a mechanically us-supported, bonded member from slipping under the influence off gravity. When employed for flocking, high green strength 7 holds fibers in place while the adhesive cures and in the laying 8 of carpet or synthetic flooring it resists curling due to the 9 shape-memory thereof acquired when stored in a roll.
Two-package urethane coatings which cure by the same reaction as set forth above with respect to adhesives have good flexibility 12 and toughness but develop film hardness slowly. It is preferable 13 that floor coatings develop hardness sufficient to accept traffic 14 rapidly to minimize down-time whether the coating be used on 15 new construction or existing sites.
16 Additionally, when urethane coatings and adhesives are 17 applied to concrete, it is currently necessary to acid-etch I the concrete prior to application. While acid-etching of the 19 concrete is a prerequisite for excellent adhesion, a higher I degree of adhesion to concrete that has not been acid-etched 21 is always desirable by virtue of the fact that when large I areas are acid-etched frequently portions thereof are either 23 missed or inadequately etched resulting in poor adhesion.
24 In accordance with the present invention, it has been found 25 that a mixture of ricinoleate urethane polyol and chlorinated 26 polyvinyl chloride (CPVC) exhibits a unique combination of 27 properties which are not achievable if either product is 28 employed lone or if either product were omitted from certain 29 formulations containing other ingredients. Chlorinated 30 polyvinyl chloride is known for its excellent adhesion to 1 rigid polyvinyl chloride, high tensile strength and inherent 2 flexibility but not as a product known to convert a ricinoleate 3 urethane polyol from a product with little tack and cohesiveness 4 to one that is tenacious as claimed in the present invention.
A chlorinated polyvinyl chloride/ricinoleate urethane polyol mixture in accordance with the present invention is 7 useful in the formulation of pressure sensitive and curable 8 adhesives, contact cements, protective coatings, curable 9 urethanes and curable coatings. Such mixtures are also useful 10 as tackifying additives, anti-slip additives, flexibilizing agents, cross-linking agents, adhesion improvers and the like.
1 The term "adhesive" as used herein is intended to include 13 broadly, adhesives, coatings and all other uses to which the 14 combination of chlorinated polyvinyl chloride and ricinoleate lo urethane polyol may be employed.

_ 18 An adhesive composition consisting essentially of a 19 solution in a suitable solvent of a ricinoleate urethane polyol 20 and a chlorinated polyvinyl chloride with the chlorinated 21 polyvinyl chloride appearing in quantities no greater than 22 approximately 90% by weight of the combined polyol and 23 chlorinated polyvinyl chloride.
I

26 The aforesaid objects and advantages may be achieved from 27 a mixture of chlorinated polyvinyl chloride and a ricinoleate 28 urethane polyol preferred embodiments of which follow.
29 The chlorinated polyvinyl chloride may be made by post I chlorinating polyvinyl chloride resin. Merely by way of : i , 1 example, the following chlorinated polyvinyl chlorides may be * *
2 employed in this invention: GENCLOR S, GENCLOR T manufactured 3 by Imperial Chemical Industries lid, London, England and 4 marketed in the USA by ICY United States, Inc., Wilmington,
5 Delaware and GOON 625X560, GOON 623X560 manufactured my
6 B. F. Goodrich Chemical Group, Cleveland, Ohio.
7 The chlorinated polyvinyl chloride content by weight should
8 not be more than approximately 90% of the chlorinated polyvinyl
9 chloride/ricinoleate urethane polyol blend. This percentage
10 excludes changes resulting from adding plasticizers, solvents,
11 fillers and the like.
12 The ricinoleate urethane polyol of this invention is made
13 by reacting an isocyanate having an average functionality of two
14 or greater with a ricinoleate polyol having an average hydroxyl lo functionality of two or greater at an isocyanate/hydroxyl 16 (NCO/OH) ratio of no greater than 0.9/1Ø The ricinoleate 17 urethane polyol resulting from this reaction substantially has 18 no reactive isocyanate groups but does have residual unrequited 19 hydroxyl groups. The methods of preparation of polyol/isocyanate 20 adduces such as the ricinoleate urethane polyol above are well 21 known in the art and need no further explanation.
22 Both aromatic and aliphatic polyisocyanates can be employed I to react with the ricinoleate polyol to make the ricinoleate 24 urethane polyol of this invention. The preferred isocyanates are Tulane diisocyanate (TDI) and diphenylmethane diisocyanate I (MID). Illustrative of other suitable polyisocyanates are 27 the following: Isophorone diisocyanate (IPDI), 4~4'4"
28 triphenylmethane triisocyanate, polyethylene polyphenyl 29 isocyanate m-phenylene, l-chlorophenylene 2,4 diisocyanates, 30 methylene-bis (4-cyclohexylisocyanate) and their equivalents.
* Tracemari;

1 The chlorinated polyvinyl chloride may be combined with the 2 ricinoleate urethane polyol by several methods. Merely by way 3 of illustration and without limiting the scope of the claims 4 hereof, some of the methods are: (a) the chlorinated polyvinyl 5 is dissolve d in the components employed in the preparation of 6 the ricinoleate urethane polyol prior to or during the reaction 7 process; by the chlorinated polyvinyl chloride is dissolved 8 in the finished ricinoleate urethane polyol; and (c) the chlorinated polyvinyl chloride is added Jo the ricinoleate 10 urethane polyol as a solution of chlorinated polyvinyl chloride dissolved in a solvent, or dissolved in a non-reactive resin or 12 a non-reactive plasticizer or combination of the same; (d) a 13 chlorinated polyvinyl chloride is added to the ricinoleate 14 urethane polyol by first dissolving in isocyanates, in blocked
15 isocyanates,in reactive phenolics, in melamine-formaldehyde,
16 in urea-formaldehyde or other resins that will chemically react
17 with the ricinoleate urethane polyol. In some cases when adding the chlorinated polyvinyl chloride by this method the chlorinated lo polyvinyl chloride would be in to part of a two-package system 20 which reacts with the other part which is the ricinoleate 21 urethane polyol.
22 The following examples are illustrative of the adhesives 23 and coatings claimed herein:

This example discloses the formulation, properties, 26 performance and testing of a two-package curing urethane 27 adhesive in accordance with the invention claimed herein. The 28 adhesive cures by the reaction of the hydroxyl groups on the 29 ricinoleate urethane polyol with the isocyanate terminated 30 prepolymer.

Those formulas of Parts A and B which contain CPVC, 21 when mixed result in the same composition.

6 Mixing and Test Procedure - The data listed in Table was 7 determined in the following manner:
8 (A) Part A and B were mixed and allowed to stand at ambient 9 temperature for thirty minutes before beginning to make test 10 samples-11 (B) Finger Tack - An 8 mill wet film was cast on glass using 12 a draw down blade. The film was given approximately a live 13 minute open time to allow the solvent to evaporate. An index 14 finger was pressed into the adhesive, withdrawn slowly, and 15 based on its "feel" was rated us oily or tacky. In the latter 16 case, a material rated as tacky not only had tack but also had 17 a high green strength, legs and grab.
18 (C) Green Strength (Finger Test) - An 8 mill wet film was
19 cast on glass using a draw down blade. The film was given approximately five minutes open time in order to allow the 21 solvent to evaporate The relative green strength was determined 22 subjectively by pressing an index finger into the adhesive and I removing it slowly. A green strength rating of ] or poor 24 indicates that little force was necessary to remove one's finger and a rating of 10 or excellent means that a very high force was 26 required to pull away from the glass.
27 (D) Green Strength (Scott Pendulum Type Tensile Tester) -28 A 5 mill wet film, 1" wide and 3" long, was cast on an aluminum 29 panel using a draw down blade. After five minutes open time to allow the solvent to evaporate, a piece of natural cotton fabric 1, 1 1 was pressed into the adhesive and rolled using a 2 pound weight.
2 The relative green strength of this lamination was determined 3 by immediately placing it in the Scott Pendulum Type Tensile 4 Tester and pulling the aluminum and fabric in opposite directions (shear adhesion). The numbers recorded were direct readings from 6 the tester with the lowest numbers being the poorest green 7 strength and the highest numbers being the strongest.
8 (E) Bond Strength - The solution was applied to two pipes 9 of Al wide natural cotton fabric using a paint brush. After a 10 five minute open time to allow the solvent to evaporate, the two 11 coated pieces of fabric were then pressed together like contact I cement. After curing, the samples were subjected to a 90 Peel 13 Strength Test using the Scott Pendulum Type Tensile Tester by 14 pulling apart at a rate of about 2 inches/minute. The numbers 15 shown are the direct readings from the tester with the lowest 16 number being the weakest bond and the highest number being the 17 strongest peel strength.

19 The principal difference between the two-package curing
20 urethane adhesive of this example and that of Example I is
21 that a different isocyanate terminated prepolymer was employed.
22 The test procedures were the same as in Example I.
