Embodiment Construction

[0030] The production specification below is 60 g / m 2 50,000 square meters of thin glass fiber mats used for waterproof coil bases are taken as an example to illustrate the specific production method of the invention:

[0031] 1) Raw material preparation: Purchase 2800kg of medium-alkali glass fiber chopped strands with a diameter of 12-13μm; 120kg of non-alkali glass fiber continuous yarn; 1000kg of dispersant hydroxyethyl cellulose acetate (recycled); 25kg of surfactant (recycled ); thermosetting resin 960kg; KH560 coupling agent 6.72kg.

[0032] 2) Slurry preparation: put glass fiber chopped strands, dispersant, surfactant and water into a mixing tank (stainless steel storage tank) and stir evenly to obtain a slurry, which is pumped into a slurry pool (concrete pool), and the slurry The glass fiber content (percentage by weight) in the material is 0.22%, the addition of hydroxyethyl cellulose acetate is about 10-12kg per 1000 liters of water, and the actual addition is adj...

Abstract

The invention provides a thin felt with glass fiber for waterproofing fetus basis and the manufacturing method, comprising short-cut silk of glass fiber, yarn of glass fiber, dispersant, surfactant and organic binder. The short-cut silk of glass fiber is middle-alkali or non-alkali, the diameter is 12-13 mum and the length is 10-18mm. The yarn of glass fiber is non-alkali the linear density is 60-70Tex. The dispersant is thickener belonging to cellulose acetate. The surfactant is quaternary ammonium cationic surfactants. The organic binder is the mixture of thermosetting resin, KH560 coupling agent and water. Said thin felt with glass fiber is produced by wet technology, which comprises producing stock, preparing slurry, adding reinforced rib yarn for sizing forming, dipping and drying so on. The felt is provided with even thickness, high intensity, no-deformation under high temperature, and high hole ratio. The waterproofing rolling-material produced by the felt as the fetus basis is provided with corrosion resistance, good waterproofness, high intensity and good weather resistance so on.

Description

Technical field: [0001] The invention relates to a waterproof coiled material base and a preparation method thereof, specifically glass fiber thin felt. Background technique: [0002] The base of asphalt waterproofing membranes for ordinary buildings is paper or polyester-cotton non-woven fabrics, among which paper-based linoleum has basically withdrawn from the market due to its poor resistance to mold corrosion and aging, and its short service life. Polyester-cotton non-woven fabric base or polyester-cotton non-woven fabric and glass fiber mesh composite base, because the composition contains a considerable proportion of plant fibers, the mold corrosion resistance and anti-aging properties of the coil are comparable to those of paper tires. No fundamental improvement is possible. A kind of glass fiber mat produced by wet process is used as the base of the waterproof membrane, because the composition does not contain any plant fibers, the resistance to mold corrosion and a...
