Problems solved by technology
[0003] Carpets contain a large amount of organic synthetic fibers. The annual consumption of carpets in our country is relatively large, and about 50 million square meters of waste carpets are produced every year. Although there are some recycling and utilization methods for waste carpets, a large number of waste carpets are usually incinerated and filled. Buried method, which wastes resources, produces a lot of dust and waste water, pollutes water bodies and atmospheric environment

Embodiment Construction
[0025] A kind of waste and old polypropylene fiber carpet fiber mortar, comprises the cement mortar prepared by each component of sand, cement, water, is characterized in that: add the carpet fiber of recycled waste and old polypropylene fiber carpet in cement mortar, and the carpet fiber length is 1~5cm, and the carpet fiber is Silky or cross-network; the amount of each component added: carpet fiber 0.8 ~ 1.0kg / m 3 , sand 1400~1500kg / m 3 , cement 200~360kg / m 3 , water 260~320kg / m 3 .
[0026] The preparation method of the above-mentioned waste polypropylene carpet fiber mortar, firstly, the waste polypropylene carpet is cleaned, dried, and rolled in sequence. The cleaning process uses an alkaline solution and is dried in the air. Adhesive layer particles; then cut the carpet into 3-5cm square flakes, put the cut small piece of carpet into a pulverizer to pulverize, and separate to obtain filamentous or cross-network carpet fibers; then wash and dry with alkaline solution a...

Abstract
Waste-polypropylene fiber carpet fiber mortar comprises cement mortar prepared from sand, cement and water. The waste-polypropylene fiber carpet fiber mortar is characterized in that: carpet fiber from recovered waste polypropylene fiber carpets is added into the cement mortar, and the carpet fiber mortar comprises 0.8-1.0 kg / m3 of the carpet fiber, 1400-1500 kg / m3 of the sand, 200-360 kg / m3 of the cement and 260-320 kg / m3 of the water. Compared with the prior art, the carpet fiber mortar is advantageous in that: 1) the carpet fiber is wide in source and low in cost, namely, the carpet fiber is prepared from the recovered waste polypropylene fiber carpets, and the cost of the carpet fiber is lower than that of common polypropylene fiber; and 2) the carpet fiber mortar has good anti-cracking effects, namely, the surface of the carpet fiber prepared from the waste carpets is coarse than the common polypropylene fiber, thus facilitating adhesion of fiber and mortar interfaces, and therefore the anti-cracking effects of the prepared fiber mortar are good.
Description
technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a waste polypropylene carpet fiber mortar, a preparation method and an application thereof. Background technique [0002] Fiber cement-based materials are a new type of composite building material that is rapidly developing in the contemporary era. Engineering applications show that the incorporation of fibers reduces the shrinkage of cement-based materials, resists the cracking of cement-based materials, and improves the impermeability and durability of cement-based materials. According to the level of fiber elastic modulus, fibers can be divided into low elastic modulus fibers and high elastic modulus fibers. High elastic modulus fibers include: steel fibers, glass fibers, carbon fibers, etc. Since glass fiber is harmful to the human body, its use is restricted. Carbon fiber is expensive and only used in some reinforcement projects. Steel fiber is the...
