Problems solved by technology

Traditional gypsum board surface stickers have defects such as dampness, airtightness, mildew, and poor flatness. After a certain period of time, the surface of the paper-faced gypsum board is prone to moisture, and yellowing, deformation, fracture, and falling off occur, and the appearance is very poor. , and the extensive use of stickers also causes a waste of natural wood resources

Embodiment 1

[0012] The preparation of embodiment 1 glass fiber coating mat

[0013] Preparation coating slurry 100kg, operation is as follows: take by weighing calcium carbonate powder 56kg, wherein 400 order light calcium carbonate and 700 order light calcium carbonate weight ratio are 4: 1, take by weighing concentration and be 52% acrylic latex 14kg, D5040 amine salt dispersant 0.1kg, thickener hydroxyethyl cellulose 5.0kg, D705 antifungal agent 0.02kg, grass green pigment paste 0.3kg, water balance.

[0014] When adding water to acrylic latex, the agitator first stirs the liquid at a low speed of 200 rpm to fully emulsify the acrylic latex; then slowly add auxiliary materials such as dispersant, antifungal agent, thickener, color paste, etc., and then increase the stirring speed to 1000 rpm, and slowly put in calcium carbonate mixed powder, and stir to form a uniform slurry.

[0015] Using glass fiber as raw material, preferably medium-alkali glass fiber with a diameter of 12 μm and ...

Embodiment 2

[0018] Preparation of slurry 100kg: take 65kg of calcium carbonate powder, wherein the weight ratio of 600 mesh light calcium carbonate and 800 mesh heavy calcium carbonate is 4:1, and mix the two; respectively weigh 12.5kg of acrylic acid latex with a concentration of 45% , D5040 type amine salt dispersant 0.32kg, thickener hydroxyethyl cellulose 4.0kg, D705 type antifungal agent 0.03kg, green pigment color paste 0.15kg, yellow pigment color paste 0.15kg, black pigment color paste 0.1kg , Water balance. Stir at a low speed of 200 rpm to fully emulsify the acrylic latex with water; then slowly add auxiliary materials such as dispersant, thickener, antifungal agent, color paste, etc., and then rotate at a high speed, controlled at 1000 rpm, slowly divide Add calcium carbonate mixed powder several times and mix evenly.

[0019] In addition, using glass fiber as raw material, glass fiber reinforced thin felt is made according to mature technology. The longitudinal tensile streng...

Embodiment 3

[0020] Embodiment 3: prepare coating slurry gross weight 100kg, take by weighing calcium carbonate powder 60kg, wherein order light calcium carbonate 500 orders: 600 order heavy calcium carbonate=4: 1, both mix; % of acrylic latex 10kg, D5040 type amine salt dispersant 0.2kg, thickener hydroxyethyl cellulose 4.5kg, D705 type antifungal agent 0.04kg, black pigment color paste 0.5kg, water surplus, according to the method of the previous example Stir into a slurry.

[0021] The above mixed paint is evenly coated on the surface of the glass fiber reinforced thin felt (one side), and the temperature of the hot air is controlled to dry the coating at a temperature of 180°C to 200°C.

Abstract

The invention relates to a glass fiber coating mat, which is used for an overlay of a gypsum board. The glass fiber coating mat is a glass fiber thin mat which is compounded with a solidified coating layer and formed by uniformly coating calcium carbonate mixed slurry on one surface of a glass fiber thin mat and then drying the glass fiber thin mat. The calcium carbonate mixed slurry is mixture which takes calcium carbonate as a main composition, and the compositions by weight percentage of the mixed slurry are: 56 to 65 percent of calcium carbonate powder, 10 to 14 percent of emulsion, 0.02 to 0.04 percent of mildew inhibitor, 0.10 to 0.32 percent of dispersant, 4.0 to 5.0 percent of thickener, the balance being water. The glass fiber coating mat replaces the prior paper overlay of the gypsum board, takes one surface of the glass fiber coating mat to be bonded and compounded with the surface of the gypsum board, and has the advantages of good air permeability, no foaming, smooth application and so on; the surface of the glass fiber coating mat can be provided with colors or patterns, thereby the glass fiber coating mat is beautiful and durable; and the gypsum overlay is made to realize non-paper, and the wood resource is saved.

Description

technical field [0001] The present invention relates to a kind of glass fiber coating mat, which is used for gypsum board veneering. Background technique [0002] Face paper gypsum board has many advantages such as light weight, heat preservation and sound absorption, so it is widely used in interior and exterior walls of homes, public places, basements or bathrooms and other interior wall panels. Traditional gypsum board surface stickers have defects such as dampness, airtightness, mildew, and poor flatness. After a certain period of time, the surface of the paper-faced gypsum board is prone to moisture, and yellowing, deformation, fracture, and falling off occur, and the appearance is very poor. , and extensive use of stickers also causes a waste of natural wood resources. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the existing gypsum board stickers, and provide a glass fiber coated mat with moisture-proof, mild...
