Problems solved by technology

[0009] To sum up, among the existing methods for the preparation of formwork cloth for construction, on the one hand, the materials used are unreasonable, resulting in the patent being inoperable; on the other hand, the single-layer material is first prepared, and then the single-layer material is Combining together, the preparation process is complicated, and at the same time, the pore structure of the pre-designed single-layer material is changed, so it is necessary to develop a feasible and easy-to-process construction template cloth
[0010] In order to overcome the disadvantages of the existing formwork cloth for construction, such as easy to wrinkle, easy to stick to the cement surface, difficult to clean the surface of the used formwork cloth, and high production cost, and to produce with lower cost and convenience, the invention provides a construction Template cloth and preparation method thereof

Abstract

The invention discloses formwork cloth for buildings and a method for preparing the formwork cloth, and relates to the field of novel building materials.The formwork cloth for the buildings comprises base cloth and coating foam liquid.The method for preparing the formwork cloth for the buildings includes carrying out working procedures of weighing and cotton feeding, secondary opening, pneumatic hopper cotton feeding, carding air laying, needling reinforcing, slitting and winding on fibrous raw materials to obtain the base cloth; preparing the coating foam liquid; delivering the coating foam liquid to surface layers of the base cloth and coating the surface layers of the base cloth; conveying the coated base cloth into a drying oven and drying and solidifying the base cloth; carrying out foam pressing treatment on the base cloth and then winding the base cloth to obtain the formwork cloth for the buildings.The fibrous raw materials are PP (polypropylene) fine-denier fibers, PP coarse-denier fibers and PP / PE (polyethylene) double-component fibers with low melting points.The formwork cloth and the method have the advantages that skin layers of the PP / PE double-component fibers with the low melting points are molten and are adhered with PP fibers during drying and solidifying, the coating foam liquid is coated on the base cloth, accordingly, the stiffness of the base cloth can be improved, and the prepared formwork cloth for the buildings is excellent in stiffness and smoothness.

Description

technical field [0001] The invention relates to the field of new building materials, in particular to a template cloth for building and a preparation method thereof. Background technique [0002] As human beings enter the 21st century, society's requirements for buildings are more high-end and modernized. Therefore, more and more new building materials are used in building construction. Permeable formwork is one of many new building materials. It not only It can eliminate the common problems of concrete quality such as air bubbles, sand lines, and sand spots on the surface of the concrete, make the concrete form a dense surface, improve the apparent quality of the concrete, and further improve the performance of the concrete, improve the durability of the concrete, and improve the wear resistance and frost resistance of the concrete , and surface tensile strength [Baidu Encyclopedia: http: / / baike.baidu.com / view / 546183.htm], has been obtained in major domestic projects such a...
