Abstract

The invention belongs to the technical field of glass fiber base cloth weaving, and provides an online weaving coating technology for a glass fiber base cloth. The coating technology comprises the steps that a woven cloth passes through a feeding roller while pretreatment feed liquid dipping is performed, then, extrusion is performed through an extrusion roller, then, heating and drying are performed at a heating and drying region, and then, take-up molding is performed to obtain the glass fiber base cloth; raw materials of pretreatment feed liquid include a permeation agent, a silane couplingagent, polyurethane and a pretreatment waterborne dispersing solution; the speed of a loom is controlled; the heating and drying region comprises a first heating and drying region and a second heating and drying region, and the woven cloth sequentially passes through the first heating and drying region and the second heating and drying region. According to the technology, online coating of a polyester polyurethane coating and drying are performed on a loom, then, coiling molding is performed, a PVC film is attached, no novel device needs to be put for performing coating of the polyester polyurethane coating, the equipment cost is saved, the product time is shortened, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of glass fiber base cloth weaving, and in particular relates to an online weaving and coating process of glass fiber base cloth. Background technique [0002] With the development of the times, PVC has gradually won the favor of people with its good performance, simple process and many other advantages, and has been accepted and recognized by more and more people. In European and American countries, PVC is the darling of the construction industry. PVC It can be seen everywhere in people's daily life. PVC can not only express the colors in nature, but also express the colors in people's fantasy. In recent years, the application of PVC to glass fiber base cloth (glass fiber base cloth) has received extensive attention. [0003] At present, the coating process of PVC film is: after weaving the glass fiber base cloth (curtain cloth and wall cloth), it is necessary to first coat the polyester polyurethane coati...
