Abstract

The invention discloses a method for modifying opened fiber reinforced regenerated artificial stone by using waste textiles, and relates to the field of building materials. The method comprises the following steps: (1) carrying out primary opening on the waste textiles and fiber waste silk; (2) further crushing the opened fibers by using a knife crusher; (3) carrying out surface modification on the fibers by using a silane coupling agent; (4) adding the modified opened fibers as a reinforcing agent in the preparation process of the regenerated artificial stone; (5) performing vacuum, vibration and compression molding; and (6) finally, putting the pressed and molded stone into a curing chamber, and drying to obtain the waste spinning modified opened fiber reinforced regenerated artificial stone. According to the method, the waste textiles are recycled in a high-value mode, the resource utilization rate is increased, meanwhile, the performance of the regenerated artificial stone is improved, and the product competitiveness of the regenerated artificial stone is improved.

Description

technical field [0001] The invention relates to the field of high-efficiency utilization of building materials and waste textiles, in particular to a recycled artificial stone reinforced with waste textiles modified opening fibers. Background technique [0002] With the advancement of science and technology, people's living standards have been greatly improved, which is reflected in people's basic necessities of life, especially clothing. Since the 20th century, scientists have developed a variety of chemical fibers, which have had a huge impact on the textile industry, and have greatly improved people's clothing standards. Three years has transformed into the current fast-selling era of clothing. Although this has improved people's quality of life, the resulting waste textiles have caused serious environmental problems. The high-quality recycling of waste textiles requires further research. Therefore, how to realize the high-quality utilization of these waste textiles and ...
