Problems solved by technology

Gypsum board is an indispensable material for decoration. The use of gypsum board will inevitably have joint problems. The traditional caulking tape is made of paper. Although it is simple and easy to implement, due to the characteristics of the paper itself, it has poor corrosion resistance and crack resistance. It is easy to absorb moisture and deform, and it is easy to mildew after absorbing moisture, which seriously affects the decoration effect
Later, glass fiber mesh caulking tape appeared. Althoug

Example Embodiment

[0024] Example 1

[0025] The preparation method of glass fiber felt for caulking of gypsum board is as follows:

[0026] 1. Slurry preparation:

[0027] First, add a certain volume of pure water to the mixing tank and slurry tank. In order to ensure that the glass fiber chopped strands can be dispersed, a certain amount of thickener, dispersant, defoamer, etc. should be added to the pure water. The auxiliary agent is formulated into white water with a viscosity of 7.0CP.

[0028] After the preparation of white water is completed, glass fibers with a diameter of 13 microns and a length of 18 millimeters and two kinds of glass fibers with a diameter of 18 microns and a length of 36 mm are added to the feed bin, weighed by a belt scale and put into white water in proportion to stir evenly to obtain Slurry, the concentration of glass fiber chopped strands in the slurry is about 0.14%. Wherein, the ratio of long fiber and short fiber is 1:1.

[0029] 2. Dehydration molding:

Example Embodiment

[0042] Example 2

[0043] The difference between the preparation method of this kind of gypsum board caulking glass fiber thin felt and embodiment 1 is:

[0044] Two specifications of glass fiber chopped strands were selected, with diameters of 6 microns and 13 microns and lengths of 6 mm and 30 mm respectively, and the weight ratio of the two was 3:1.

[0045] The slurry concentration of the glass fiber in the slurry preparation section is 0.11%, and the viscosity of the prepared white water is 6.2CP.

[0046] The dehydration flows in the first to fifth zones of the dehydration molding section are: 310m 3 , 330m 3 , 1100m 3 , 800m 3 and 270m 3 .

[0047] The mass percentage of urea-formaldehyde resin, acrylate, coupling agent and color paste in the binder is 72:25:2:1. The concentration of the binder emulsion configured in the wet felt dipping process is 30%.

[0048] The technical performance index of the glass fiber thin felt of gained under this method is as follow...

[0050] Example 3

[0051]The difference between the preparation method of this kind of gypsum board caulking glass fiber thin felt and embodiment 1 is:

[0052] Chopped glass fibers of three specifications are selected, with diameters of 10 microns, 13 microns, and 13 microns, and lengths of 12 mm, 12 mm, and 36 mm, respectively, and the weight ratio of the three is 1:1:1.

[0053] The slurry concentration of the glass fiber in the slurry preparation section is 0.15%, and the viscosity of the prepared white water is 7.8CP.

[0054] The dehydration flows in the first to fifth zones of the dehydration molding section are: 470m 3 , 480m 3 , 1000m 3 , 600m 3 and 100m 3 .

[0055] The mass percent of urea-formaldehyde resin, acrylate, coupling agent and color paste in the binder is 80:15:4.5:0.5. The concentration of the binder emulsion configured in the wet felt dipping process is 15%.

[0056] The technical performance index of the glass fiber thin felt of gained under th...

Abstract

The invention relates to a glass fiber mat for gypsum board caulking and a preparing method thereof. The glass fiber mat comprises glass fiber chopped strands, wherein the glass fiber chopped strands have two specifications; for one specification, diameter is 3-14 microns, and length is 6-18 millimeters; for the other specification, diameter is 12-20 microns, and length is 12-36 millimeters; the weight ratio of the two specifications of glass fiber chopped strands is (1.0-3.0):1. The glass fiber mat is high in water resistance and does not deform or become moldy after absorbing moisture; fiber disperse is uniform, thickness is stable, and holes are reasonable; stiffness is moderate, structural stability is high, appearance is excellent, and follow-up coating is convenient; pore distribution is reasonable, fiber dispersion is uniform, thickness is stable, pores are small, advantages of paper gridding cloth and advantages of glass fiber gridding cloth are both realized, interface friendliness is realized with binders and gypsum slurry for decoration, the mat can be firmly combined with a gypsum board after coating, and surface is smooth.

Description

technical field [0001] The invention belongs to the field of gypsum board wall surface decoration, and in particular relates to a thin glass fiber felt for caulking of gypsum boards and a preparation method thereof. Background technique [0002] With the rapid development of the economy and the continuous improvement of people's living standards, the requirements for office and living environments are getting higher and higher. The decoration industry has sprung up, and the decoration requirements are beautiful and high-end. Gypsum board is an indispensable material for decoration. The use of gypsum board will inevitably have joint problems. The traditional caulking tape is made of paper. Although it is simple and easy to implement, due to the characteristics of the paper itself, it has poor corrosion resistance and crack resistance. It is easy to absorb moisture and deform, and it is easy to mildew after absorbing moisture, which seriously affects the decoration effect. La...
