Embodiment 1

[0038] The invention discloses an environment-friendly white glass wool product. The glass wool product is composed of glass wool fibers and a total liquid; the specific preparation steps are:

[0039] A The glass wool fiber is obtained by the centrifugal blowing method. The manufacture of glass wool fibers by the centrifugal blowing method is a traditional process, which mainly includes three steps of glass wool raw material preparation, high temperature melting and fiber formation. Since it is a traditional process (for details, please refer to "Glass Fiber Application Technology" textbook), so no more details.

[0040] B Use the prepared total adjustment solution to evenly spray on the glass wool fibers for curing to form glass wool products. The spraying of the total liquid in this process step is similar to the spraying method and process equipment of the traditional formaldehyde-containing adhesive, but it is necessary to ensure that the curing temperature is controlled...

Embodiment 2

[0048] A kind of environment-friendly white glass wool product, this glass wool product is made of glass wool fiber and total adjusting liquid; Its specific preparation steps are:

[0049] A The glass wool fiber is obtained by the centrifugal blowing method.

[0050] B Use the prepared total adjustment solution to evenly spray on the glass wool fibers for curing to form glass wool products. The injection amount of the total liquid adjustment accounts for 15% of the solid content of the glass wool fiber. The total liquid adjustment needs to be heated to 50-70°C ten minutes before use. During the production process, the pH value of the adhesive solution is strictly controlled at 4 or so, the curing temperature is 250°C.

[0051] The composition of the total liquid adjustment in the present invention according to parts by weight is: 26 parts of environmentally friendly formaldehyde-free glass wool adhesive (each part of adhesive includes: 170 groups of polymethacrylic acid; 50 gro...

Abstract

The invention belongs to the field of glass wool production, and especially relates to an environment-friendly type white glass wool product. The glass wool product does not contain free phenol and formaldehyde. The glass wool product is composed of glass wool fiber and a total regulating liquid. A preparation method comprises specific steps that: A, glass wool fiber is obtained with a centrifugal blowing method; B, prepared total regulating liquid is uniformly ejected onto the glass wool fiber; curing is carried out, such that the glass wool product is formed. The total regulating liquid comprises components of, by weight: 18-26 parts of an environment-friendly type formaldehyde-free glass wool fiber bonding agent, 3-6 parts of a coupling agent, 0.3-1 part of an auxiliary cross-linking agent, 1-3 parts of a curing catalyst, 1-3 parts of a surfactant, and 70-80 parts of a solvent.

Description

technical field [0001] The invention belongs to the field of glass wool production, in particular to an environment-friendly white glass wool product which does not contain free phenol and formaldehyde. 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. This raw material contains free phenol and formaldehyde, and it is difficult to degrade. It tends to volatilize free phenol and formaldehyde for a long time during use, which is harmful to human health. The situation is seriously threatened. The invention patent (CN1962517B) discloses a hot-melt adhesive composition, which does not contain formaldehyde and has no pollution to the environment. However, no application has been found in glass wool products. Contents of the invention [0003] The object of the present invention is to provide an environment-friendly white glass wool product, which can solve th...
