Epoxy and epoxy novolac adhesive binders for structural reinforcement systems of building structures

نویسندگان

چکیده

Today, along with the conventional materials and technologies for reinforcement of building structures, structural systems based on polymer composites are rise. A system consists reinforcing filler (normally, carbon fiber fabric or cloth) adhesive binder. This paper investigated modification epoxy nobake binders to provide a higher thermal resistance mechanical strength. The influence novolac resins processing physical properties adhesives, is studied. It found that substitution 20-40 % resin in binder increases tensile strength by 40-50 %, flexural modulus 20 reduces strain, glass transition temperature. From point view, it more reasonable use liquid functionality f =2.5 than semisolid =3.6.

Synthesis of iso-epoxy-amphidinolide N and des-epoxy-caribenolide I structures. Initial forays.

Two strategies for the projected total synthesis of the phenomenally potent antitumour macrolides amphidinolide N (1) and caribenolide I (2) are described. The title compounds are introduced as challenging and unique targets for chemical synthesis, and their retrosynthetic analysis is presented. The synthesis of the four defined key building blocks (10, 39, 67 and 72), required for the construc...

Designing Machine Tool Structures With Epoxy Concrete

Ab stract: The materials used in the manufacture of machine tools structures affects the metal removal rate; accuracy and surface finish of the products. The materials, in turn, have influence over the method of production, lead times and overall costs of the machine tool structures. Over a period of time machine tool builders relied on conventional materials, for the fabrication of machine too...

Occupational dermatitis from a one-component naphthalene type epoxy adhesive.

In an electronics plant, a new one-component naphthalene type epoxy resin was used as an adhesive for reinforcing a circuit board. The resinous part of the adhesive consisted of diglycidyl ether of bisphenol A (DGEBA) and 1,6-bis(2,3-epoxypropoxy)naphthalene type epoxy resins. The hardener was methylhexahydrophthalic anhydride (MHHPA). Of 54 workers, 15 (27.8%) were diagnosed to have work-relat...

Properties of Epoxy/SiO2 - and Epoxy/ZrO2 - Nanocomposites

The synthesis, structure and mechanical properties of inorganic organic nanocomposites are investigated: The systems consist of an aliphatic amine cured Bisphenol-F-based epoxy resin as organic matrix and SiO2 and ZrO2 nanoparticles as inorganic fillers. Silica and zirconia nanoparticles have been prepared in two different size ranges, one in the upper nano range (30-60 nm) and other in the low...

Modelling Cyclic Moisture Uptake in an Epoxy Adhesive

This paper presents a methodology for predicting moisture concentration in an epoxy adhesive under cyclic moisture absorption-desorption conditions. The diffusion characteristics of the adhesive were determined by gravimetric experiments under cyclic moisture conditions and the dependence of diffusion coefficient and saturated mass uptake on moisture history was determined. Non-Fickian moisture...
