Problems solved by technology

Although commercially available glue sticks often have these properties, such products have not been found to be exceptionally suitable or accepted for use in Do-It-Yourself (DIY) applications such as home improvement and repair, arts and crafts and construction projects, due to the increased adhesive properties required in these applications

example

[0039] The present disclosure is further illustrated by the following examples, which should not be construed in any way as limiting its scope. On the contrary, it is to be clearly understood that various other embodiments, modifications and equivalents thereof, which may occur to those skilled in the art after reading the description herein, may be employed without departing from the scope of the appended claims .

example 1

[0041] A first exemplary formulation was prepared that included an oxazoline polymer and casein to provide the desired adhesive properties. The formulation compositions are shown in Table 1 below.

[0042]

[0043] This formulation was prepared by the following exemplary process: (i) blending Aquazol 50 and Aquazol 200 together, adding deionized water and then storing the resulting premix at elevated temperature (e.g., 80°C) for 6-8 hours, followed by Mix gently until the mixture is essentially homogeneous; (ii) add glycerol and antifoam and mix gently; (iii) separately, by combining organic amine and water and add casein, then mix the solution Prepare the casein solution until it is a homogeneous solution; (iv) add the casein solution to the batch and mix the solution; (v) add sodium stearate and Bienba wax powder together and add to the batch; (vi) Maintain heat at 75-80°C and mix at low spread for about 15-30 minutes or until it is homogeneous; (vii) add silane coupling...

example 2

[0046] A second exemplary formulation was prepared that included a polyurethane dispersion (PUD) in the formulation for further enhanced adhesion to various surfaces. The formulation compositions are shown in Table 2 below.

[0047]

[0048] This formulation was prepared by the following exemplary process: (i) blending Aquazol 50 and Aquazol 200 together, adding deionized water and then storing the resulting premix at elevated temperature (e.g., 80°C) for 6-8 hours, followed by Mix gently until the mixture is essentially homogeneous; (ii) add glycerol and antifoam and mix gently; (iii) separately, by combining organic amine and water and add casein, then mix the solution Prepare the casein solution until it is a homogeneous solution; (iv) add the polyurethane dispersion to the batch and continue mixing; (v) add the casein solution to the batch and mix the solution; (vi) add the Add sodium stearate to batch; (vii) maintain heat at about 75-80°C and mix on low spread for abo...

Abstract

The present invention provides adhesive formulations and a method for making adhesive formulations. An adhesive formulation includes at least one oxazoline polymer and casein. The method of making adhesive formulations includes combining at least one oxazoline polymer and casein to form the adhesive formulation. The present invention futher provides glue sticks made using these adhesive formulations and methods.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Application No. 62 / 262,612, filed December 3, 2015, which is incorporated herein by reference in its entirety. technical field [0003] The present disclosure relates generally to adhesive-containing products and formulations, and more particularly to oxazoline-based adhesive formulations. Background technique [0004] Glue sticks are commonly used in the stationery field to glue paper and other craft materials to each other or to other materials, and such products are often used by adults and children. Commercial glue stick formulations typically utilize polyvinylpyrrolidone (PVP) or modified poly(vinyl acetate) (PVA) polymers, although PVP-based formulations generally Provides better performance including ease of lubrication, package stability and better adhesion. [0005] Although modified PVA-based products can be formulated to deliver faster tack onset, they of...
