Embodiment 1

[0012] 70 parts of vinylidene chloride polymer emulsion, 28 parts of pure acrylic emulsion, 1.8 parts of nano-silica, 2 parts of antimony trioxide, 0.04 part of sodium polyacrylate dispersant, mix well in the presence of appropriate amount of water, and coat the mixture Dry the liquid glass fiber cloth in an oven at 105°C for about 90 seconds until the glue is completely dry, then remove it from the oven. The obtained mesh cannot be ignited with fire, the warp and weft are positioned well, the hand feels non-sticky and elastic, and the appearance is similar to ordinary glass fiber mesh without yellowing.

Embodiment 2

[0014] 70 parts of vinylidene chloride polymer emulsion, 37 parts of styrene-acrylic emulsion, 2.2 parts of nanoclay, 2.3 parts of antimony trioxide, 0.075 parts of sodium polyacrylate dispersant, mix well in the presence of an appropriate amount of water, and apply the mixture liquid Dry the glass fiber cloth in an oven at 115°C for about 90 seconds until the glue is completely dry, then remove it from the oven. The obtained mesh cannot be ignited with fire, the warp and weft are positioned well, the hand feels non-sticky and elastic, and the appearance is similar to ordinary glass fiber mesh without yellowing.

Embodiment 3

[0016] 70 parts of vinylidene chloride polymer emulsion, 32 parts of styrene-butadiene emulsion, 4.6 parts of nanoclay, 2.3 parts of antimony trioxide, 0.045 parts of sodium alkylnaphthalene sulfonate dispersant, mix well in the presence of appropriate amount of water, and coat the Dry the glass fiber cloth of the mixture liquid in an oven at 110°C for about 85 seconds until the glue is completely dry, then remove it from the oven. The obtained mesh cannot be ignited with fire, the warp and weft are positioned well, the hand feels non-sticky and elastic, and the appearance is similar to ordinary glass fiber mesh without yellowing.

Abstract

The invention discloses a frame retardant glass fiber mesh, which is formed by submerging a mesh in a flame retardant adhesive, and is characterized in that: the flame retardant adhesive comprises a PVDC latex, a strengthened positioning emulsion, an inorganic nano filler, an assistant flame retardant and a dispersant of which a dry matter ratio is 2:(0.5-1.5):(0.05-0.35):(0.05-0.25):(0.001-0.1). The flame retardant glass fiber mesh has the advantages that: the technological process is simple and convenient to operate and control, raw materials have low cost, and the production process has no pollution; the obtained glass fiber mesh product has good flame retardancy; and the indexes, such as hand feeling, elasticity, positioning effect, strength and the like all meet related requirements. The mesh prepared by the invention can be used in the industrial and civil buildings and places without limitation to halogenated flame retardancy.

Description

technical field [0001] The invention relates to a flame-retardant glass fiber mesh cloth, in particular to the preparation process conditions of a flame-retardant glass fiber mesh cloth and the selection and compounding method of flame-retardant glue. Background technique [0002] Flame-retardant fiberglass mesh is used in many industrial and civil buildings. This mesh is made by coating flame-retardant positioning glue on the glass fiber mesh gray cloth and drying. The usual flame retardant glue is made of PVC resin paste diluted with a large amount of organic solvents to form a glue with good fluidity and good coating or a halogen-free polymer emulsion compounded with a large amount of expensive flame retardants. Either a large amount of organic matter is released into the environment during processing to pollute the environment, or the cost is extremely high and cannot meet the needs of market competition. Contents of the invention [0003] The object of the present in...
