Description
Technical Field
The invention belongs to the field of building materials, and particularly relates to a polypropylene composite material and a preparation method thereof, and a plastic tile.
Background
Generally, the main parts of a building are defined as the ground, the facade (inner and outer wall) and the roof, respectively, and each part has building materials corresponding to the part. For a long time, the knowledge of roofing has been focused on the understanding of tile. In the traditional sense, the primary function of roofing is to provide water resistance. Therefore, in the northern area with water shortage for thousands of years, most houses only need to daub on the inclined plane or plane roof; in the south of rainy days, the densely arranged mud tiles are required to be paved on the roof. In the generation, the clay tile is the only 'coat' on the roof.
However, as the concept of building energy conservation is more and more deeply bored in the world, the performances of environmental protection, heat insulation, heat preservation, corrosion resistance and the like become the indispensable connotations of roof materials as well as waterproofness. Roofing engineering is becoming a large stage of a new type of environment-friendly and energy-saving material, and plastic tiles are the first choice of the current roofing.
The roofing of modern buildings has the function of not only shielding the house from wind and rain. For example, a planted roof is used for planting plants. For another example, heat insulation performance is important for heat insulation roofing, and heat dissipation and ventilation of roofing need to be considered in construction. Particularly, with the arrival of the industrialized era, roofing materials required by a large number of industrial plants form a new large market. Compared with the characteristics of the roofing material of the dwellings, the roofing material of the industrial factory building not only requires the materials to be waterproof, heat-insulating and heat-preserving, but also needs to be light, environment-friendly and corrosion-resistant. It is this need that has led to the development of new roofing materials. New plastic tile materials which are light in weight, beautiful, environment-friendly, waterproof, fireproof, sound-proof and heat-insulating have come to modern roofs.
The national wall material "fifteen" program clearly indicates that: the novel composite wall material and the roof waterproof material which are efficient, energy-saving, soil-saving, waste-utilizing and environment-friendly, light in weight, high in strength, heat-preserving, heat-insulating and fireproof have must be vigorously researched and developed. With the economic prosperity and the technological progress of China, the living conditions and the living standard of people are continuously improved, modern buildings gradually develop to high quality and high grade, and the functional requirements are continuously improved. When the traditional roofing material can not meet the development requirement of the building industry, various novel roofing materials are produced. According to the popular trend of international building material development, the roofing material is developed in the directions of light weight, beauty, environmental protection, water and fire prevention, sound insulation, heat insulation and the like. However, asbestos tiles, cement tiles, and recently emerging color steel tiles are difficult to satisfy the requirements of environmental protection and energy saving in terms of performance. Aiming at the problems of fragility, heavy weight, easy corrosion and the like of the traditional roofing building material, a large number of domestic enterprises begin to explore and innovate roofing composite materials in order to meet all functional requirements of high strength, light weight, energy conservation, soil conservation, waste utilization and environmental protection proposed in the fifteen planning.
