investigation the properties of acrylated epoxidized soy oil-wheat straw particle board
نویسندگان
چکیده
the acrylated epoxidized soy oil (aeso) was synthesized from epoxidized soy oil and its properties were investigated. wheat straw particle boards were produced by the synthesized resin with 8% and 13% contents based on straws weight at three pressing times: 8,10 and 12 min. boards’ modulus of rapture, modulus of elasticity, internal bonding, minimum degree of thickness change and water absorption were investigated. the swelling and water absorption results showed that the highest amounts of boards’ modulus of rapture, modulus of elasticity and internal bonding with board samples of lowest thickness belong to boards made from 13% resin content with 12 minute pressing time; and these amounts were in range of en particleboard standard and the produced particleboard which totally compete with wood particleboard. the aeso-wheat straw particleboard due to its non-formaldehyde emission and bio-based structure can substitute wood particleboard effectively.

The effect of wheat straw bleaching on some mechanical properties of wheat straw/LDPE biocomposites
Using biocomposites containing wheat straw (WS) and synthetic polymers like polyethylene (PE) has gained tremendous popularity, but its application in the packaging industry is not substantial. Due to the prevalence of raw WS color which manifests itself in the WS/LDPE biocomposite, the present investigation is dedicated to fabricate a bleached WS/LDPE composite. Thus, raw WS and the pulp of WS...

One-Pot Conversion of Epoxidized Soybean Oil (ESO) into Soy-Based Polyurethanes by MoCl₂O₂ Catalysis.
An innovative and eco-friendly one-pot synthesis of bio-based polyurethanes is proposed via the epoxy-ring opening of epoxidized soybean oil (ESO) with methanol, followed by the reaction of methoxy bio-polyols intermediates with 2,6-tolyl-diisocyanate (TDI). Both synthetic steps, methanolysis and polyurethane linkage formation, are promoted by a unique catalyst, molybdenum(VI) dichloride dioxid...

Environmental concerns focusing on the emission of volatile organic compounds (VOCs) can be ameliorated via the development and use of very lowto no-VOC coatings. Ultraviolet (W) radiation curing is an effective means of incorporating low molecular weight reactive species into high performance, onvolatile polymers. The advantages of W curing include rapid polymer network formation on heat sensi...
