preparation example Construction
[0024] see Figure 1-3 , the invention provides a technical solution for the preparation method of a textile fabric composite board: comprising the following steps:
[0025] S1, according to manufacturing needs, calculate the size of the board and cloth, the ratio of melamine-formaldehyde resin for impregnation, impregnation time, dehydration pressure, high-temperature curing temperature and time of cloth, the ratio of melamine-formaldehyde resin for curing, coating thickness, plate pressure, Standing time, composite plate high temperature curing temperature and time;
[0026] S2, the cut cloth is dipped in the dipping tank, and an industrial vibrating rod is used for tamping to ensure that the air bubbles in the cloth are fully released, so that the resin can fully cover each fiber, and dehydration treatment is carried out after a certain period of time;
[0027] S3, adjusting the roller pressure of the dehydrator to remove the liquid, and drying the dehydrated fabric natura...
specific Embodiment
[0034] Specific examples are as follows:
[0035] It is necessary to produce a batch of 30cm×150cm colored flower fabric decorative panels, which need to be continuous in design and color. According to the production process and process, we cannot guarantee that all fabrics can be cut well. Therefore, fabrics with a width of 160cm and solid wood multi-layer composites with a width of 150cm×200cm are selected. sheet.
[0036] The first step, fabric treatment: firstly select a melamine formaldehyde resin with a certain viscosity for impregnation according to the thickness of the fabric and the diameter of the weaving thread, pour the resin into the impregnation tank, and cut the fabric according to the length of 210cm according to the shrinkage rate calculation After that, put it into the dipping tank for impregnation. The impregnation time is 20 minutes. During this period, an industrial vibrating rod is used to vibrate, so that the air bubbles in the cloth wire diameter can be...
