preparation example Construction

[0022] Further, the preparation method of above-mentioned fiberglass mesh adhesive tape, comprises the following steps:

[0023] Step 1: Put 0.5-1.0 parts of acrylic acid, 0.3-0.5 parts of hydroxyethyl acrylate, 29-32 parts of isooctyl acrylate, 9-11 parts of butyl acrylate and 7-10 parts of vinyl acetate into the emulsification tank, turn on the stirring and mixing for 10 Minutes to obtain mixed products;

[0024] Step 2: Put half of the total amount of the mixed product into the reaction furnace, put 40-44 parts of ethyl acetate in the reaction furnace, turn on the stirring, feed nitrogen, the speed of the reaction furnace is 25 revolutions per minute, and the temperature is raised to 74-76°C;

[0025] Step 3: Mix 0.2-0.3 parts of lauroyl peroxide and 7-9 parts of ethyl acetate, and titrate in the reaction furnace. Boiling phenomenon will appear after titration for about 20 minutes, and the temperature will rise to 85-86 ° C. Stop titration, and the temperature Drop to 63-...

Embodiment 1

[0041] Step 1: Put 0.7 parts of acrylic acid, 0.4 parts of hydroxyethyl acrylate, 30 parts of isooctyl acrylate, 10 parts of butyl acrylate and 8 parts of vinyl acetate into the emulsification tank, turn on the stirring and mixing for 10 minutes to obtain a mixed product;

[0042] Step 2: Put half of the total amount of the mixed product into the reaction furnace, put 42 parts of ethyl acetate in the reaction furnace, turn on the stirring, feed nitrogen, the speed of the reaction furnace is 25 revolutions per minute, and the temperature is raised to 75°C ;

[0043] Step 3: Mix 0.25 parts of lauroyl peroxide and 8 parts of ethyl acetate, and titrate in the reaction furnace, the temperature rises to 85°C, stop the titration, the temperature drops to 65°C, continue the titration, open the emulsification tank at the same time, in the reaction Put the other half of the mixed product in the furnace, continue to titrate to 150 minutes, cool down and unload the glue after 4 hours of h...

Embodiment 2

[0051] Step 1: Put 0.5 parts of acrylic acid, 0.3 parts of hydroxyethyl acrylate, 29 parts of isooctyl acrylate, 9 parts of butyl acrylate and 7 parts of vinyl acetate into the emulsification tank, turn on the stirring and mixing for 10 minutes to obtain a mixed product;

[0052] Step 2: Put half of the total amount of the mixed product into the reaction furnace, put 40-44 parts of ethyl acetate in the reaction furnace, turn on the stirring, feed nitrogen, the speed of the reaction furnace is 25 revolutions per minute, and the temperature is raised to 74°C;

[0053] Step 3: Mix 0.2 parts of lauroyl peroxide and 7 parts of ethyl acetate, and titrate in the reaction furnace. Boiling will appear after about 20 minutes of titration, and the temperature will rise to 85°C. Stop titration, and the temperature will drop to 63°C. Continue Titrate, open the emulsification tank at the same time, put the other half of the mixed product in the reaction furnace, continue to titrate to 150 m...

Abstract

The invention relates to the technical field of adhesive tapes, and especially relates to a glass fiber grid adhesive tape and a preparation method thereof. The glass fiber grid adhesive tape comprises a glass fiber grid cloth layer and a glue layer coated on the surface of the glass fiber grid cloth layer, wherein the glue layer is prepared by mixing the following components in parts by weight; 0.5 to 1.0 part of acrylic acid, 0.3 to 0.5 part of hydroxyethyl acrylate, 29 to 32 parts of iso-octyl acrylate, 9 to 11 parts of butyl acrylate, 7 to 10 parts of vinyl acetate, 47 to 53 parts of ethylacetate, 0.2 to 0.3 part of lauroyl peroxide and 7 to 9 parts of ethyl acetate. The glass fiber grid cloth keeps dimensional stability in a very wide temperature range, and can provide longitudinal and transverse stable dimensions without deformation. The adhesive tape has the advantages of high viscosity, high biaxial tensile strength, softness, fitness, wear resistance, water resistance and moisture resistance, and can also be used for firmly adhering rough or irregular surfaces.
