example 1

[0064] In this example, a total of 16.2 grams of MgCl 2 -6H 2 O was dissolved in 29.9 g of deionized water. To this solution was added 0.4 grams of 12.1% p-TSA solution and 2.4 grams of 45.5% TA solution. Subsequently, 9.7 grams of PVAc (55% solids content) were blended into the reaction, followed by 32.1 grams of MgO. After mixing well, 9.4 grams of soy flour was added and the whole reaction was stirred for 30 minutes until homogeneous. The order of addition of the materials was found to be unimportant. In this example, MgO:MgCl 2 The molar ratio is 10:1. PVAc was 9.7% of the total solids of the formulation and soy flour was 16.2% of the total solids of the formulation. The resulting adhesive, referred to herein as Composition A, was used to prepare samples using ABES as described above.

example 2

[0066] In this example, a total of 20.4 grams of MgCl 2 -6H 2 O was dissolved in 178.1 g of deionized water. To this solution was added 60.5 grams of MgO, and the solution was stirred for 15 minutes. To this solution was added 29.3 g of SPI, and the mixture was stirred for 30 minutes. In this example, MgO:MgCl 2 The molar ratio is 15:1. SPI is 28.5% of the total solids of the formulation. The resulting adhesive, referred to herein as Composition B, was used to prepare samples using ABES as described above and plywood samples as described above.

example 3

[0068] In this example, a soy flour PAE control sample was prepared by dispersing 105.0 grams of PAE followed by 62.8 grams of soy flour in 170.8 grams of deionized water while mixing. Subsequently, 0.6 grams of sodium metabisulfite was added, followed by 62.5 grams more of soybean flour. Stir the blend for five minutes until homogeneous. The resulting adhesive, referred to herein as Composition C, was used to prepare samples using the Automated Adhesion Evaluation System (ABES) as described above and plywood samples as described above.

[0069] Figure 5 ABES intensity data for Composition A (bar 200) and Composition B (bar 202) are shown. Figure 5 Additionally included is data on adhesives typically used to bond lignocellulosic materials, including: Composition C-Soy-PAE (entry 204), urea formaldehyde (UF) (entry 206), phenol formaldehyde (PF) (entry 208) and 210) and PVAc (article 212). For phenol formaldehyde, higher curing temperatures are required to obtain full cur...

Abstract

Provided are adhesive materials for fire resistant applications, methods of using these adhesive materials on lignocellulosic and other like substrates, and composite materials including lignocellulosic substrates and these adhesive materials. In addition to being fire-resistant, the composites formed from the substrates and adhesive materials may be also durable to moisture. The adhesive materials may include at least one proteinaceous-containing material and at least one magnesium oxychloride material. Other materials may be present as well, in some embodiments. For example, an adhesive material may include a solvent or a vinyl polymer. In some embodiments, water may be used as a solvent and the adhesive material may be referred to as an aqueous adhesive material. Some examples of suitable vinyl polymers include but are not limited to polyvinyl alcohol (PVOH), polyvinyl acetate (PVAc) and vinyl acetate / ethylene (VAE).

Description

[0001] Cross References to Related Applications [0002] This application, filed under 35 U.S.C. §119(e) requirement 12 / 02 / 2013, is entitled: "ADHESIVE MATERIALS AND METHOD OF FORMINGLIGNOCELLULOSIC COMPOSITES USING SUCH ADHESIVES )”, which is incorporated herein by reference in its entirety. technical field [0003] The present invention relates generally to sticky materials and methods of using the same, and more particularly to sticky materials having magnesium oxychloride compounds and proteinaceous materials, and methods of forming lignocellulosic composites using said sticky materials such that the sticky materials are water resistant And fireproof. Background technique [0004] Lignocellulosic composites are made from small pieces of cellulose material bound together using adhesives. In general, wood or other lignocellulosic materials are first processed to produce veneers, particle boards, fibers and chips. The binder is then added to the lignocellulosic material...
