    Abstract: A porous polypropylene modified fibre, the method for preparing which comprises mainly mixing the fibre grade chips of polypropylene and the additives, then forming a high-strength porous polypropylene filaments by high-pressure spinning and multiple stretching, said additives include the surfactant(s) for improving the hydrophility of the fibre and the inorganic micropowder(s) for forming concavo-convex holes while the filaments are being drawn. An important use of the end product is to improve the spalling resistance of a concrete structural member in the condition of high temperature by adding the staple of said product to a concrete or mortar. The staple from present invention has a high dispersibility, surface binding power and excellent mechanical behaviors, the building fire hazard raised by concrete structural member spalling under high temperature is lowed considerably because of the addition of the staple.

    Abstract: A pigment composition, the material color chip thereof and the method for making the same, are disclosed in the present invention. The pigment composition comprises 995-1005 parts in weight of film-forming binder; 2.85-3.05 parts in weight of PY42 whose pigment content is 60%; 0.34-0.36 parts in weight of PR101 whose pigment content is 65%; and 0.04 parts in weight of PBK7 whose pigment content is 9%. The major components of the film-forming binder are acrylic copolymer and TiO 2 , wherein the amount of acrylic copolymer is 30-40% and the amount of TiO 2 is 8-12%. The TiO 2 which is used as white pigment is ISO 591 R2 type, and the purity=95%, the oil absorption
