Abstract
A construction material and a process for the preparation thereof, which material comprises a plastic component constituted of a thermoplastic resin; and a filler component constituted of a mineral and/or organic filler at least equal in weight to the amount of the plastic component and the individual particles of which are coated or encapsulated with a polyethylene or polypropylene wax having a molecular weight of from 1,000 to 10,000, a thermofluid high molecular weight polymer, or a silicate coating. The composite material is low in cost and may be processed by conventional techniques, e.g., by molding, extrusion or machining, to produce a variety of useful products.
Claims25
A construction material which comprises a mixture of:
- a. a plastic component constituting at least one thermoplastic resin;
- and
- b. a filler component consitituting at least one mineral and/or organic filler in an amount at least equal in weight to the amount of said plastic component, the individual particles of the filler being coated or encapsulated with a polyethylene or polypropylene wax having a molecular weight of from 1,000 to 10,000, a thermofluid high molecular weight polymer, or a silicate coating material.
