Embodiment 1

[0027] In this production process, the spraying method of the environmentally friendly formaldehyde-free glass wool adhesive is similar to that of the traditional adhesive, and the curing temperature is controlled at: 150-300°C. The environmentally friendly formaldehyde-free glass wool adhesive is used ten minutes before use. It needs to be heated to 60-70°C, the solid content of the adhesive is controlled to be ≥ 20%, the inner veneer is reinforced with composite glass fiber, and the outer veneer material of the board is pasted.

Embodiment 2

[0029] In this production process, the spraying method of the environmentally friendly formaldehyde-free glass wool adhesive is similar to that of the traditional adhesive, and the curing temperature is controlled at: 100-200°C. It needs to be heated to 50-65°C, the solid content of the adhesive should be controlled to be ≥15%, the inner veneer is reinforced with composite glass fiber, and the outer veneer material of the board is pasted.

Embodiment 3

[0031] In this production process, the spraying method of the environmentally friendly formaldehyde-free glass wool adhesive is similar to that of the traditional adhesive, and the curing temperature is controlled at 150-250°C. It needs to be heated to 60-65°C, the solid content of the adhesive should be controlled to be ≥30%, the inner veneer is reinforced with composite glass fiber, and the outer veneer material of the board is pasted.

[0032] After several experiments, we put forward the above three sets of analysis data and conducted experiments in the laboratory. After comparison, the test results of Example 1 are the most ideal: the glass wool air duct plate has no free formaldehyde volatilization, no peculiar smell, and the problem of glass fiber scattering is also eliminated. Does not exist, meets the requirements of environmental protection, and has no harm to the human body after use.

Abstract

The invention relates to a non-formaldehyde glass wool wind pipe plate, wherein its production comprises high-temperature fusing; making fiber; ejecting non-formaldehyde and glass wool adhesive, solidifying, shaping, strengthening the inner adhesive surface; slicing and packing. The non-formaldehyde glass wool adhesive injection method is same as traditional method; the solidify temperature is controlled at 100-300Deg. C; and said adhesive should be heated to 50-70Deg. C before using, and its solid content is higher than 10%.

Description

Technical field: [0001] The invention belongs to the production of glass wool boards, and relates to a method for using an environment-friendly formaldehyde-free glass wool adhesive. Background technique: [0002] At present, the adhesive used in the production of glass wool products in China uses thermosetting phenolic resin as the main raw material, which contains a large amount of free formaldehyde, which is often easily volatilized during use, posing a serious threat to human health. Invention content: [0003] The purpose of the present invention is to provide an environment-friendly formaldehyde-free glass wool air duct plate, which mainly solves the problems of volatilization of free formaldehyde and escape of glass wool fibers in the existing glass wool air duct plate. [0004] The invention relates to a method for using an environment-friendly formaldehyde-free glass wool adhesive. [0005] In order to solve the problems of the technologies described above, the p...
