CN103031722B - Novel glass fiber combination mat impregnating compound with high film-forming property - Google Patents

Abstract

The invention relates to a novel glass fiber combination mat impregnating compound with a high film-forming property and belongs to the field of chemical technical formulas. The novel glass fiber combination mat impregnating compound with the high film-forming property consists of the following raw materials in percentage by weight: 2 to 5 percent of auxiliary, 4 to 8 percent of polytetrafluoroethylene emulsion, 6 to 12 percent of acrylic resin emulsion, 1 to 5 percent of vinyl acetate and the balance of water. The use quantity of the PTFE (polytetrafluoroethylene) emulsion is reduced, and meanwhile, production cost is reduced; a good protection film can be formed on a mat surface, and in the aspect of hand feeling, the mat surface is provided with slippery surface burr bulges and the slippery surface burr bulges are smaller than before; and thickness of a mat is reduced by 0.5 mm, so that gaps between fibers on a mat layer is reduced. The formula has the greatest improvement that vinyl acetate (705) is added; comprehensive performance of a product is not reduced and even product quality is improved; and moreover, stripping resistance and stiffness are improved.

Description

High film build glass fiber composite mat sizing agent

Technical field

The present invention relates to a kind of high film build glass fiber composite mat sizing agent, belong to chemical process formulation art.

Background technology

For the glass fiber composite mat that current existing sizing agent deals, some carpet veneers and base cloth cohesive force poor, the voidage between fiber is large, and feel is felt like jelly.Especially peeling force and air penetrability are difficult to reach industry requirement.Wherein air penetrability causes because sizing agent does not form diaphragm at carpet veneer mouth greatly; after not forming the filter bag that diaphragm and interfibrous voidage will make greatly glass fiber composite mat make, in use fine solid particle can enter the space between carpet veneer, causes space to block.The resistance that deduster is run increases, and increases energy consumption and the potential safety hazard of deduster, reduces life of bag filter, virtually increase production cost.

Summary of the invention

According to the deficiencies in the prior art, the technical problem to be solved in the present invention is: provide a kind of high film build glass fiber composite mat sizing agent, felt face can form good diaphragm, the interfibrous space of carpet veneer diminishes, and increases peeling force and stiffness.

The technical solution adopted for the present invention to solve the technical problems is: provide a kind high film build glass fiber composite mat sizing agent, be made up of the raw material of following percetage by weight:

Auxiliary agent: 2-5%;

Ptfe emulsion: 4-8%;

Emulsion acrylic resin: 6-12%;

Vinyl acetate resin: 1-5%;

All the other are water.

Described auxiliary agent is the mixed solution of vinyltriethoxysilane, tween and alcohol.

The invention has the beneficial effects as follows:

1. reduce the consumption that PTFE emulsion is soft, reduce production cost simultaneously.

2. can form good diaphragm on felt face, in feel, felt face has cunning shape surface spikes projection less than in the past.

3. the thickness decline 0.5mm of felt is that the interfibrous space of carpet veneer diminishes.

4. improve filtering accuracy and the service life of filtrate.

5. the maximum improvements of this formula, add vinyl acetate resin (705), the combination property of product is not fallen, and even also improves product quality, and increases peeling force and stiffness.

Detailed description of the invention

Below in conjunction with embodiment, invention is described further:
