Embodiment Construction

[0012] The composite emulsion of this embodiment is prepared from the following raw materials in parts by weight: epoxy-modified styrene-acrylic emulsion 55 with a solid content of 50-60%, nano-ceramic powder transparent liquid 4.5 with a solid content of 50%, and nano-zirconia 2.5 , Soluble polyimide resin 2.5, N-methylpyrrolidone appropriate amount, polyvinyl alcohol 0.2, deionized water 14, sodium dodecylbenzene sulfonate 0.2.

[0013] The preparation method of the epoxy resin modified styrene-acrylic emulsion with high strength and high toughness for dip coating of a kind of alkali-resistant glass fiber mesh cloth, the preparation method is:

[0014] (1) First put the soluble polyimide resin into N-methylpyrrolidone, stir until it is completely dissolved, add nano-ceramic powder transparent liquid, 1 / 2 weight part of sodium dodecylbenzene sulfonate, continue to stir and mix Emulsify for 2.5 hours to obtain a pre-emulsified polyimide solution for subsequent use;

Abstract

The invention discloses high-strength high-toughness epoxy resin modified styrene-acrylic emulsion for dip-coating alkali-resistant glass fiber lattice cloth. According to the compound emulsion, soluble polyimide resin and nanosized ceramic powder transparency liquid are prepared into copolymer milk-globules and the milk-globules are distributed uniformly and efficiently in epoxy-modified styrene-acrylic emulsion, so as to achieve the effects of toughening and strengthening, heat resisting, corrosion resisting and the like, glass fibers coated and treated through the compound emulsion has excellent toughness and strength, and is less likely to fracture and deform, alkali-resisting and heat-resisting, and economical and durable.

Description

technical field [0001] The invention relates to the technical field of preparation of modified styrene-acrylic emulsion, in particular to an epoxy resin-modified styrene-acrylic emulsion with high strength and high toughness for dip coating of alkali-resistant glass fiber mesh cloth and a preparation method thereof. Background technique [0002] With the continuous advancement of building energy conservation, the application of glass fiber mesh for thermal insulation is becoming more and more extensive. Mainly used for thermal insulation system of expanded polystyrene board thin plastering external wall, external wall thermal insulation system of rubber powder polystyrene particles, wall thermal insulation system of inorganic vitrified microbead thermal insulation mortar, external thermal insulation system of rock wool board external wall, etc. Wall insulation. It plays an anti-crack protection effect on the insulation layer, and does not damage the insulation layer due to ...
