specific Embodiment 1

[0022] This embodiment relates to an acid and alkali resistant wallpaper for laboratory use, including an acid and alkali resistant layer and a base layer. The acid and alkali resistant layer is formed by mixing the following raw materials: furan 11-15%, phenolic vinyl resin 36-40%, organic Silicon monomer resin 36-40%, catechol 1-5%, pyrogallic acid 1-5%, tris 1-5% and dopamine 1-5%, the base layer is made of non-woven fabric .

[0023] In the present invention, the acid and alkali resistant layer is formed by mixing the following raw materials: furan 11%, phenolic vinyl resin 40%, organic silicon monomer resin 40%, catechol 2%, pyrogallic acid 2%, trihydroxy Methylaminomethane 2.5% and Dopamine 2.5%.

[0024] In the present invention, the acid and alkali resistant layer is formed by mixing the following raw materials: furan 12%, phenolic vinyl resin 39%, organic silicon monomer resin 39%, catechol 2.5%, pyrogallic acid 2.5%, trihydroxy Methylaminomethane 2.5% and Dopamine ...

specific Embodiment 2

[0029] This embodiment relates to a preparation method of acid and alkali resistant wallpaper for laboratory use, comprising the following steps:

[0030] S1: Prepare raw materials in proportion.

[0031] S2: heat-melt phenolic vinyl resin and silicone monomer resin;

[0032] S3: Add furan, catechol, and pyrogallic acid to the colloid, and stir evenly;

[0033] S4: Immerse the colloid in a mixed aqueous solution of Tris and dopamine for 15 minutes and take it out;

[0034] S5: Pour the colloid hot melt into the mold again, and press the non-woven fabric on the colloid acid and alkali resistant layer;

[0035] S6: standing for cooling, polishing the acid and alkali resistant layer.

[0036] The present invention uses the mixture of phenolic vinyl resin and organosilicon monomer resin as the base material of the acid and alkali resistant layer, which has high acid and alkali resistance, and by using furan, the unsaturated bonds in the epoxy vinyl resin and the organosilicon r...

Abstract

The invention discloses acid-and-alkali-resistant wallpaper for a laboratory and a preparation method thereof. The laboratory acid and alkali resistant wallpaper comprises an acid-and-alkali-resistant layer and a base layer, and the acid-and-alkali-resistant layer layer is prepared by mixing the following raw materials: 11-15% of furan, 36-40% of novolac vinyl resin, 36-40% of organosilicon monomer resin, 1-5% of catechol, 1-5% of pyrogallic acid, 1-5% of tris(hydroxymethyl)aminomethane and 1-5% of dopamine. The base layer is made of non-woven fabric. According to the acid-and-alkali-resistant wallpaper for the laboratory and the preparation method of the acid-and-alkali-resistant wallpaper, the novolac vinyl resin and the organosilicon monomer resin are mixed to serve as a base material of the acid-and-alkali-resistant layer, so that the acid-and-alkali-resistant wallpaper has high acid-and-alkali-resistant performance; and by adoption of thefuran, unsaturated bond structures in the epoxy ethylene resin and the organosilicon resin can be subjected to bond breakage and react with an aliphatic amine modified curing agent or an aliphatic curing agent to form a new chain structure, so that new bond connection is formed between the two resins, and the curing hardness of the resins is improved.

Description

technical field [0001] The invention relates to the field of wallpaper, in particular to an acid and alkali-resistant wallpaper for laboratories and a preparation method thereof. Background technique [0002] Wallpapers are more and more popular in people's daily life because of their incomparable characteristics such as various colors, rich patterns, luxurious style, safety and environmental protection, convenient construction, and affordable prices.
