MAN-MADE MINERAL FIBRE FOR THREE-DIMENSIONAL REINFORCEMENT OF A CEMENT PRODUCT |
摘要 |
The present invention provides a bicomponent fiber for three-dimensional reinforcement of a cement product characterized in that it represents a coaxial core-coat fiber wherein the core comprises a thermoplastic polymer and the coat either comprises thermoplastic polymer resistant to environment having pH>11 and one or more hydrophilic and/or surface active substance(s) in an amount of 3 to 30%% of the total weight of the coat, or the coat comprises thermoplastic polymer resistant to environment having pH>11 grafted with active or unsaturated monomers of one or different kinds constituting 3 to 25% of total weight of the coat, wherein the surface tension of the coat is at least 45 mN/m. The invention also provides a method for production of said fiber, a cement product comprising such fiber and a method of production of said cement product.
