Problems solved by technology

Also, the disadvantage of these wood products is that they feel a lot like plastic due to the presence of PE
For these reasons, the known plastic-based wood products are hardly suitable for the production of furniture, certainly not for the production of solid furniture

Embodiment Construction

[0009] The composition for producing imitation wood according to the present invention comprises 30-40wt% of polyvinyl chloride (PVC) resin and 30-40wt% of rice husks and / or A mixture of peanut shells. The term "mesh" characterizes the mesh width or mesh width of a sieve and thus serves as a measure for expressing the particle or particle size. The smaller the mesh value, the larger the particle size of the bulk material to be described. For example, there are two tables from the National Bureau of Standards that convert grid width mesh values ​​to mm.

[0010] The PVC material used is not particularly limited. In particular, recycled PVC can also be used. For example, a PVC suspending resin with a K value of 60 to 70 is suitable. The K value is considered to be a number calculated from the measurement of the viscosity of a dilution of the polymer, a measure of the degree of polymerization or molecular size. K values ​​are used in resin specifications.

Abstract

The invention provides imitation wood. The present invention also relates to a composition for producing imitation wood, said composition comprising 30-40wt% of PVC resin and 30-40wt% of rice hulls with a particle size of 0.42-0.25mm (40-60 mesh) and / or a mixture of peanut shell powder. The invention further relates to a wood imitation produced by extrusion of the composition according to the invention. The imitation wood according to the present invention has a very similar appearance and feel to wood and can be processed with traditional carpentry tools. Due to the high weather resistance of the imitation wood, especially in wet or humid environments, the imitation wood can be painted and bonded with additives without any problems and is suitable for outdoor applications.

Description

[0001] This application is a divisional application of the invention patent application whose filing date is February 19, 2010, application number is 201080066283.X, and the invention name is "imitation wood". technical field [0002] The present invention relates to the production of building materials, especially imitation wood, which resembles wood in appearance and feel. Background technique [0003] Known plastic-based wood products, so-called wood-plastic composites ("WPC"), are produced from a mixture of wood and polyethylene / polypropylene (PE / PP). These materials do not require final surface treatment and are mainly used for the production of flooring for outdoor use. Wood products known to be predominantly plastic cannot be painted or painted only with considerable effort. Furthermore, the disadvantage of these wood products is that they feel a lot like plastic due to the PE content. For these reasons, the known plastic-based wood products are hardly suitable for ...
