Problems solved by technology
[0003] The purpose of the present invention is to solve the above problems, and to design a crack repair anti-stretch anti-crack cloth and its manufacturing method, which solves the problem that although the existing anti-crack cloth can play a bonding role, its own tensile strength is low , especially the middle flat surface, is prone to cracks due to vehicle rolling, and the structural strength is relatively low, which is prone to deformation problems

Embodiment
[0033]Embodiment: In the specific implementation process, the crack repair stretch-resistant and anti-crack cloth is produced according to the following steps, step S1, loosening materials; step S2, configuring small materials; step S3, combing into a web; step S4, superimposing and bonding; Step S5, edge banding; Step S6, roll; Step S7, packing;
[0034] Since the short fiber is compressed tightly after the finished product is opened, the short fiber needs to be opened first. According to the product requirements, fibers of different deniers or different colors need to be mixed into the opener in a certain proportion. The opening time is 30 minutes, and light 2. During this period, configure the waterproof layer coating, add a certain amount of polyurea powder into the stirring tank and inject water, and carry out 30min under the condition of 22-25℃. Stir to obtain polyurea coating; 3. The short-fiber cotton after opening is sent to the quantitative feeding machine, and the q...

Abstract
The invention discloses a crack repair stretch-resistant and anti-crack cloth and a manufacturing method, comprising a bottom layer and a surface layer, the surface layer is laid on the bottom layer, and a stretch-resistant layer structure is filled between the bottom layer and the surface layer; the present invention The beneficial effect is that the crack repairing stretch-resistant and anti-crack fabric manufactured according to the method adopts a composite design, and a polyurethane fiber mesh layer with good flexibility and tensile strength is embedded between a pair of barbed wire layers. Increase the stiffness and crack resistance of the anti-crack cloth through barbed wire, and increase the flexibility and tensile strength through the fiber layer, so that it can rebound better after deformation. The function is to use the polyurethane fiber layer with good flexibility and tensile strength as the core, and use the barbed wire mesh with high rigidity as the surface, which effectively avoids the cracking of the anti-cracking cloth due to repeated rolling after repairing.
Description
technical field [0001] The invention relates to the technical field of anti-crack cloth, in particular to a crack repair stretch-resistant anti-crack cloth and a manufacturing method. Background technique [0002] The anti-split cloth is made of filaments or short fibers laid out into a net shape through different equipment and processes. After needle punching and other processes, different fibers are intertwined with each other, entangled and fixed to make the fabric standardized, making the fabric soft and plump , Thick, stiff, to achieve different thicknesses to meet the requirements of use, anti-crack cloth has a good fabric gap, good adhesion, because the fiber is soft, it has a certain tear resistance, good deformation adaptability, and at the same time It has very good plane drainage capacity, the surface is soft and has many gaps, and it has a good coefficient of friction, which can increase the adhesion of soil particles, etc., and can prevent fine particles by prev...
