Problems solved by technology

[0004] The relative brittleness of the material resulting from the necessary high filler content has proven to be disadvantageous for these plastic moldings
Therefore, the resistance of plastic molded parts to shocks and shock loads, that is, impact resistance, is sometimes not high enough

Embodiment

[0025] 1. Manufacture of casting compound

[0026] First, a binder component was prepared by dissolving 2.0 kg of polymethyl methacrylate (PMMA) having a molecular weight of 50,000 to 250,000 g / mol in 8.0 kg of methyl methacrylate (MMA). 200 g of trimethylolpropane trimethacrylate (TRIM) was added to the above mixture as a crosslinker along with various peroxides such as Peroxan BCC, Laurox and Trigonox.

[0027] To produce the casting compounds of Comparative Examples 1 and 2 and Examples 1 and 2, the binder component is mixed with inorganic fillers, functionalized organosiloxanes and where appropriate glass fibers or keratin fibers and the mixture is homogenized. change. The respective weight ratios of the components are given in Table 1 below:

Abstract

In order to provide a curable casting compound for producing plastic molded parts, comprising a binder component on the basis of polymerizable monomers selected from the group consisting of methyl acrylate or methyl methacrylate and having a proportion of about 40 to about 85% by weight of one or more inorganic filler materials, which compound can be used for producing plastic molded parts having an increased impact strength, it is proposed for the casting compound to comprise 0.1 to 0.5% by weight of keratin fibers.

Description

technical field [0001] The invention relates to a curable casting compound for the production of plastic moldings, comprising a binder component based on polymerizable monomers and one or more inorganic fillers in proportions of from about 40 to about 85% by weight. Background technique [0002] This type of cast compound has been used for a long time in kitchens and sanitary areas for the manufacture of kitchen sinks, kitchen worktops, washbasins, bathtubs, etc. A relatively high proportion of inorganic fillers distributed in the polymer matrix formed by the binder components is necessary here to obtain the required material properties for the site, such as, for example, sufficient high temperature resistance and Surface scratch resistance. Furthermore, the visual structure of the surface of the plastic molding, such as, for example, a decorative granite surface, can be achieved through the choice of one or more fillers. [0003] The production of kitchen and sanitary art...
