Embodiment 1

[0013] The present invention uses organic raw materials to make glass wool adhesive, the main component of which is formaldehyde-free acrylic resin, adding appropriate amount of organic and inorganic salts, stirring at room temperature for 1-3 hours, and then heating to 120- 140°C; react for 5 hours and dehydrate; its weight components are: polymethacrylic acid 120-150 groups; alkylbenzenesulfonic acid 30-40 groups; silane 1-3 groups; polyvinyl alcohol 30-50 groups ; Ammonium sulfate 2 to 10 groups.

Embodiment 2

[0015] The present invention is realized in the following way: an environment-friendly formaldehyde-free glass wool adhesive, the present invention uses organic raw materials to make the glass wool adhesive, the main component of which is formaldehyde-free acrylic resin, adding an appropriate amount of organic and For inorganic salts, stir at room temperature for 1-2 hours, then heat to 140-150°C; react for 1 hour and dehydrate; its weight components are: polymethacrylic acid 150-170 groups; alkylbenzenesulfonate Acid 30-50 groups; Silane 0-2 groups; Polyvinyl alcohol 30-60 groups; Ammonium sulfate 5-12 groups.

Embodiment 3

[0017] The present invention is realized in the following way: an environment-friendly formaldehyde-free glass wool adhesive, the present invention uses organic raw materials to make the glass wool adhesive, the main component of which is formaldehyde-free acrylic resin, adding an appropriate amount of organic and For inorganic salts, stir at room temperature for 1-3 hours, then heat to 120-140°C; react for 3 hours and dehydrate; its weight components are: polymethacrylic acid 130-150 groups; alkylbenzenesulfonate Acid 20-35 groups; Silane 2-4 groups; Polyvinyl alcohol 30-50 groups; Ammonium sulfate 6-8 groups.

[0018] After several tests, we put forward the above three sets of analysis data and conducted tests in the laboratory. After comparison, the test result of Example 1 is the most ideal: the glass wool adhesive does not contain formaldehyde and has no peculiar smell, and does not volatilize during use. or escape any harmful ingredients.

Abstract

The invention discloses an environmental protective non-formaldehyde glass wool additive, which comprises the following parts: 100-170wt% polymethacrylic acid, 10-50wt% sodium alkyl benzene sulphonate, 0-5wt% silicane, 10-60wt% polyvinyl alcohol and 0-12wt% ammonia sulfate. The preparing method comprises the following steps: adding fitful organic and inorganic salt; stirring for 1-4h under normaltemperature; heating to 100-160 Deg C; reacting 5h; dehydrating.

Description

Technical field: [0001] The invention belongs to the preparation and synthesis of a zero-formaldehyde environment-friendly adhesive. The invention uses organic raw materials such as methacrylic acid and acrylic acid to replace the traditional formaldehyde-containing glass wool adhesive with phenolic resin as raw material. Background technique: [0002] The current domestic glass wool adhesive uses formaldehyde-containing phenolic resin, which releases free formaldehyde during the production and use of glass wool, causing certain harm to the human body and restricting the development and expansion of the application field of glass wool products. Invention content: [0003] The purpose of the present invention is to provide an environmentally friendly formaldehyde-free glass wool adhesive, which mainly solves the problem of formaldehyde in the existing glass wool adhesive and the volatilization of formaldehyde caused by the use of phenolic resin. , due to the serious consequ...
