Problems solved by technology

However, because the color steel tile is not resistant to acid and alkali, the metal surface is easy to rust, easy to leak, and has poor durability. At the same time, the heat insulation effect of the color steel tile is not good, and the temperature inside the house changes significantly with the outside temperature in summer or winter; To a certain extent, resin tiles can overcome the shortcomings of color steel tiles that are not resistant to corrosion and have poor sound and heat insulation effects, and can be used as a substitute for color steel tiles. However, because the molecular structure of synthetic resin tiles determines its The performance of softening under low temperature and embrittlement at low temperature, easy to decompose and easy to age are common problems of synthetic resin tiles. Therefore, the mechanical strength becomes lower under the environment of long-term ultraviolet decomposition of the roof's cold and hot cycles, and then bears the wind pressure and snow pressure, so that its service life is greatly improved. shortened, cannot meet the performance requirements of modern buildings such as sound insulation and heat insulation, long service life, etc.
[0003] At the same time, in the rural areas of our country, most of the crop straws are directly burned, which not only fails to be effectively used, but also causes pollution to the environment.

Abstract

The invention discloses a straw-fiber-reinforced polyester tile and a manufacturing method thereof. The manufacturing method comprises the following steps: evenly stirring and mixing straw fiber, metaphenylene polyester resin, mica powder, wollastonite powder and other raw materials according to a certain formula, and carrying out hot compacting. The straw-fiber-reinforced polyester tile has the characteristics of sound insulation, heat insulation and long service life in the colored steel tile and synthetic resin tile which are commonly used at present, can effectively utilize the straw resources, is beneficial to protecting the ecological environment, and lowers the production cost and use cost.

Description

Technical field: [0001] The invention relates to a building roof waterproof material, in particular to a straw fiber reinforced polyester tile, which belongs to the field of roof building materials. Background technique: [0002] At present, color steel tiles are widely used in large-format tiles in building roofing materials. However, because the color steel tile is not resistant to acid and alkali, the metal surface is easy to rust, easy to leak, and has poor durability. At the same time, the heat insulation effect of the color steel tile is not good, and the temperature inside the house changes significantly with the outside temperature in summer or winter; To a certain extent, resin tiles can overcome the shortcomings of color steel tiles that are not resistant to corrosion and have poor sound and heat insulation effects, and can be used as a substitute for color steel tiles.
