Description

Technical Field

[0001] The invention relates to the field of glass fiber corrugated paper molding, in particular to a molding process for compounding single-layer glass fiber corrugated paper with glass fiber flat paper. Background Art

[0002] Fiberglass paper is a paper structure made of glass fiber as the main raw material. Fiberglass paper has the advantages of high strength, good water resistance, excellent fire resistance, good chemical stability, etc. Fiberglass paper corrugated forming is the process of processing fiberglass paper into corrugated shape.

[0003] Since the fiberglass paper itself is brittle and stiff, it is prone to cracking and rebounding when bent into a corrugated shape, resulting in failure to form. At the same time, the fiberglass paper surface is prone to "hair standing", that is, a large number of glass fibers stand upright on the surface. At the same time, "hair falling" may occur during the processing, that is, the glass fibers fall off, affecting the quality and performance of the corrugated shape after forming. This characteristic greatly increases the difficulty of corrugated forming of fiberglass paper. Summary of the invention

The specific organic alcohols can be ethylene glycol, propylene glycol, etc., which penetrate into the fiber of the glass fiber paper, and form hydrogen bonds with groups such as hydroxyl groups on the fiber surface to reduce the cohesive force between the fibers, so that the fibers become soft, thereby achieving the effect of softening the glass fiber paper; the surfactant can be polyoxyethylene type, etc., which can reduce the surface tension of the glass fiber paper surface, make it easier for water to penetrate into the fiber, and promote the swelling and softening of the fibers; the plasticizer can be phthalates, fatty acid esters, etc., which can be inserted between the fiber molecular chains of the glass fiber paper, weaken the force between the molecular chains, increase the flexibility and mobility of the molecular chains, thereby making the glass fiber paper as a whole soft, and the agent The concentration of organic alcohols is 20% to 35%, the concentration of surfactants is 1% to 5%, and the concentration of plasticizers is 5% to 10%. By immersing the first roll of glass fiber paper through the agent, the first roll of glass fiber paper can be softened, so that the first roll of glass fiber paper can form a wavy structure in the subsequent extrusion molding without cracking, etc., which is convenient for the formation of glass fiber corrugated paper structure. The first roll of glass fiber paper after immersion passes through the water control roller 4, and the first roll of glass fiber paper is squeezed to remove excess agent on the surface of the first roll of glass fiber paper.

The composite glue roller 9 can apply glue between the two convex strips on the lower corrugated creasing roller 7 during the extrusion molding of the first roll of glass fiber paper, so that when the upper corrugated creasing roller 6 and the lower corrugated creasing roller 7 extrude the first roll of glass fiber paper, the corrugated top of the first roll of glass fiber paper is applied with glue, so that the first roll of glass fiber paper is subsequently bonded with the second roll of glass fiber paper to form a glass fiber corrugated paper structure;

[0045] S4, passing the second roll of glass fiber paper together with the first roll of glass fiber paper after wave forming through the laminating roller 10, the wave top area of ​​the first roll of glass fiber paper will be bonded to the surface of the second roll of glass fiber paper under the action of the composite glue coating, so as to form a glass fiber corrugated paper structure, wherein the laminating roller 10 is installed on the left side of the lower wave creasing roller 7, and the first roll of glass fiber paper and the second roll of glass fiber paper will be bonded together after passing between the laminating roller 10 and the lower wave creasing roller 7.

Then the first roll of glass fiber paper is bonded to the second roll of glass fiber paper to form a glass fiber corrugated paper structure. This molding process reduces the difficulty of glass fiber paper corrugation molding, making it easier for glass fiber paper to be extruded into a corrugated structure and composited with glass fiber flat paper to form a glass fiber corrugated paper structure.
