Investigating the use of peanut meal: a potential new resource for wood adhesives

Abstract

This study was conducted to evaluate the potential of peanut meal (PM) to produce plywood adhesives via sodium dodecyl sulfate (SDS) and ethylene glycol diglycidyl ether (EGDE) modification.

Properties of a new renewable sesame protein adhesive modified by urea in the absence and presence of zinc oxide

“…For the sesame protein adhesives, sesame protein (10 g) was added to the urea solution (80 mL, 3 mol L À1 ), and the mixture was stirred for 20 min at 25 C. Zinc oxide (0, 4, 8, 12, 16, and 20% based on the mass of sesame protein) was added to the sesame protein adhesive, and the mixture was stirred for 220 min at 25 C to obtain a urea-modied sesame protein adhesive (USP) and ZnO-modied sesame protein adhesive containing urea (ZUSP) (4,8,12,16, and 20% ZUSP).…”

“…Many researchers have investigated plant protein-based adhesives such as soy protein-based adhesive, peanut protein-based adhesive, and cotton protein-based adhesive. [5][6][7][8][9][10][11] However, the low-water resistance and solid content of the plant protein-based adhesives have limited their application in the wood adhesive industry. 12 It is essential to improve water resistance of plant protein-based adhesives to expand their application.…”

Exfoliating nanomaterials in canola protein derived adhesive improves strength and water resistance

“…[1][2][3] However, increasing concerns on petrochemical based wood adhesives such as environmental impact, potential health hazards due to formaldehyde emission, and non-renewability have renewed the interest in developing green, renewable alternatives. [3][4][5][6] Biobased adhesives, derived from protein, and polysaccharides were widely used before they were replaced by synthetic ones during the World War II. 1,2,5,6 However, the challenge remains with regard to developing cost-effective and performance comparative adhesives from these biobased materials.…”

“…2,7 Historically, casein, gelatin, blood and soy proteins were applied for various adhesive applications. 2,4,8 More recently, the possibility of using other protein sources such as wheat gluten, 9 cottonseed protein, 10 triticale protein, 5,11 and canola protein 7 were studied.…”

Effects of inorganic filler on performance and cost effectiveness of a soybean‐based adhesive

“…The TGA results in Figure indicate that the filler‐modified adhesives had three distinct weight‐loss stages at 25–120 °C (Stage I), 120–450 °C (Stage II), and 450–800 °C (Stage III). The loss in Stage I was attributed to evaporation of residual moisture and small molecule loss, that in Stage II was attributed to polymer degradation in the cured adhesive, and that in Stage III was attributed to filler degradation . The cured adhesives modified by LCC and HCC not only had lower polymer degradation temperatures and mass residual ratios than the control adhesive but also exhibited filler degradation at approximately 650 °C, indicating lower crosslinking density and poor HCC–adhesive and LCC–adhesive interactions.…”
