摘要:
A fiberglass reinforced composite is provided with improved physical properties. The fiberglass reinforced composite incorporates core-shell rubber nanoparticles within the resinous binder of the composite and/or within a sizing composition coated directly onto the individual glass fibers.
摘要:
A process for producing a composite product comprising fibers of a lignocellulosic material or natural fibers and a plastics material utilizes a liquid or particulate binder formulation comprising a thermoset resin and a thermoplastic polymer, monomer, or oligomer. A composite product is formed for use as or in forming a feedstock in plastics manufacture may be broken down under heat and mechanical shearing in a plastics extrusion machine to release the major fraction of the fibers, or the product may be useful as an intermediate product in other form or as an end product.
摘要:
The present invention provides: A melamine resin foam obtained by foaming a resin composition comprising a melamine / formaldehyde condensate, a blowing agent and an isocyanate, wherein the melamine / formaldehyde condensate is obtained by synthesis using a silane coupling agent. The invention further provides a process for producing a melamine resin foam as well as a melamine / formaldehyde condensate. The melamine resin foam of the present invention is free from the problems of the prior art, has solved the problem of fragility without impairing the good flame retardancy and low thermal conductivity inherently possessed by melamine resin foams and causes not danger during the production.
摘要:
The present invention is directed to an active-ingredient-coated urea-formaldehyde polymer having an active ingredient concentration greater than 35 wt.-%, based on the weight of the active-ingredient-coated urea-formaldehyde polymer, wherein said active ingredient is one or more urease inhibitor(s).
摘要:
Urea-formaldehyde (UF) resin binder compositions modified with a starch are described. The binder compositions may include about 1 wt.% to about 10 wt.% of a starch. In addition, fiber reinforced composites are described. The composites may include organic or inorganic fibers and a polymer matrix formed from a binder composition. The binder composition may include a UF resin and about 1 wt.% to about 10 wt.% of a starch.

摘要:
The present invention provides: a melamine resin foam obtained by foaming a resin composition comprising a melamine/formaldehyde condensate, a blowing agent and an isocyanate, a process for producing the above melamine resin foam, which comprises foaming a resin composition comprising a melamine/formaldehyde condensate, a blowing agent and an isocyanate, and a melamine/formaldehyde condensate used in the production of the above melamine resin foam, which is obtained by reacting melamine and formaldehyde in the presence of a silane coupling agent. The melamine resin foam of the present invention is free from the problems of the prior art, has solved the problem of fragility without impairing the good flame retardancy and low thermal conductivity inherently possessed by melamine resin foams, and causes no danger during the production.
