Abstract
A material composition comprises, on the one hand, a particulate material and, on the other hand, a binder which is provided as a coating on the material particles. The binder has at least two solid phases (13, 14), of which one harder phase (14) is configurationally stable and a softer phase (13) is plastic and readily deformable at temperatures below the melting point of the binder. A method for producing the above material comprises the steps that at least two components included in the binder are melted and mixed, whereafter kneading takes place during cooling. The material composition is usable, for example, as a play material, educational material, for sculptures or prototypes or as landscape architectonic material.
Claims22
A material composition comprising a particulate material and a binder which is provided as a coating on particles of the particulate material, wherein the binder has at least two solid phases of which one harder phase is configurationally stable and a softer phase is plastic and readily deformable at temperatures below a melting point of the binder, wherein the material composition comprises the binder kneaded together with the particulate material during cooling from the melting point of the binder so that the softer phase of the binder is attained.
A method of producing a material composition comprising a particulate material and a binder with at least two included components which are solid at room temperature, comprising heating components included in the binder to above their respective melting points and mixing the components, adding the particulate material and the binder, and kneading the particulate material together with the binder composition during cooling from the melting point of the binder material to obtain the material composition having, at room temperature, one solid, soft phase which is plastic and readily deformable.
A binder adapted to have at least two solid phases, of which two phases one harder phase is configurationally stable and a softer phase is plastic and readily deforinable at temperatures below a melting point of the binder and is attained after kneading of the binder during cooling from a melting point of the binder, the binder being in the softer phase.
