Problems solved by technology

The substrates used for these two types of plastic floor leather are all non-woven fabric materials. The non-woven fabric substrate is easy to shrink and deform at high temperature, which will affect the stable production of plastic floor leather, resulting in uneven surface of plastic floor leather and uneven thickness of floor leather. Uniformity, poor dimensional stability, etc., which restrict the application of plastic floor leather in middle and high-end decoration

Embodiment Construction

[0031] The production specification below is 30g / m 2 Take 50,000 square meters of plastic floor leather base material glass fiber thin felt as an example, and illustrate the specific production method of the invention:

[0032] 1) Raw material preparation: purchase 1535kg of medium-alkali glass fiber chopped strands with a diameter of 9 μm; Resin 325kg; KH560 coupling agent 3.7kg;

[0033] 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 0.12%, the addition of hydroxyethyl cellulose acetate is about 10-12 kg per 1000 liters of water, and the actual addition is adjusted according to the viscosity of the slurry to ensure that the viscosity of the slurry reaches 10-12 kg. 12CP is better, the amount of surfactant added is to...

Abstract

The invention discloses a thin felt with glass fiber for the substrate of plastic floor ant the manufacturing method, comprising short-cut silk of glass fiber, dispersant, surfactant and organic binder. Said short-cut silk of glass fiber is middle-alkali or non-alkali, the diameter is 9-10 mum and the length is 6-12mm. Said dispersant is thickener belonging to cellulose acetate. Said surfactant is quaternary ammonium cationic surfactants. The organic binder is the mixture of polyethylene acetate emulsion thermosetting resin, KH560 coupling agent and water. Said thin felt with glass fiber is produced by wet technology, which comprises producing stock, preparing slurry, sizing forming, dipping and drying so on. The product is provided with high compactness, even thickness, widely applied temperature, and no-deformation under high temperature. The plastic floor surface with the felt as the substrate, is provided with flat and smooth, no shrinkage deformation, no-bending, no mildewing and stable dimension.

Description

Technical field: [0001] The invention relates to a plastic floor leather substrate, in particular to a thin glass fiber felt. Background technique: [0002] Plastic floor has two kinds of polyvinyl chloride coil floor and polyvinyl chloride block floor, and plastic floor leather in the present invention refers to polyvinyl chloride coil floor. This kind of plastic floor leather is made of polyvinyl chloride resin as the main raw material, adding appropriate additives, and is produced on a sheet-like continuous substrate through a coating process. There are two kinds of PVC coiled flooring and dense PVC coiled flooring with substrate. The substrates used for these two types of plastic floor leather are all non-woven fabric materials. The non-woven fabric substrate is easy to shrink and deform at high temperature, which will affect the stable production of plastic floor leather, resulting in uneven surface of plastic floor leather and uneven thickness of floor leather. Unifo...
