Embodiment 1

[0023] Firstly, the silica-coated ammonium polyphosphate is prepared: the ammonium polyphosphate powder is immersed in the silica sol for 24 hours, and then the mixture is dried, crushed, and ground to obtain the silica-coated ammonium polyphosphate.

[0024] Slowly add 10 parts of ammonium salt modified acrylate emulsion to 100 parts of water glass, and manually stir to make the two evenly mixed. Then add 4 parts of magnesium myristate, 1 part of silane coupling agent, 5 parts of tetrapod zinc oxide whiskers, stir evenly at a speed of 800r / min, then add 1 part of xanthan gum and 3 parts of dioxide Silicon-coated ammonium polyphosphate, 3 parts of molybdenum oxide and 10 parts of water were stirred and dispersed for 30 minutes at a rotation speed of 800r / min. Finally, add 6 parts of silicon powder and stir evenly.

Embodiment 2

[0026] Slowly add 15 parts of ammonium salt modified acrylate emulsion to 100 parts of water glass, and manually stir to make the two evenly mixed. Then add 6 parts of magnesium myristate, 1.5 parts of silane coupling agent, 7.5 parts of tetrapod zinc oxide whiskers, stir evenly at a speed of 800r / min, then add 2 parts of xanthan gum and 5.5 parts of dioxide Silicon-coated ammonium polyphosphate, 4 parts of molybdenum oxide and 20 parts of water were stirred and dispersed for 45 minutes at a speed of 800r / min. Finally, add 9 parts of silicon powder and stir evenly.

Embodiment 3

[0028] Slowly add 20 parts of ammonium salt modified acrylate emulsion to 100 parts of water glass, and manually stir to mix the two evenly. Then add 8 parts of magnesium myristate, 2 parts of silane coupling agent, and 10 parts of tetra-needle zinc oxide whiskers. After stirring evenly at a speed of 800r / min, add 3 parts of xanthan gum and 8 parts of dioxide The silicon-coated ammonium polyphosphate, 5 parts of molybdenum oxide and 30 parts of water were stirred and dispersed for 60 minutes at a rotation speed of 800r / min. Finally, add 12 parts of silicon powder and stir evenly.

Abstract

The invention discloses a water glass-based multiple-effect wood adhesive and a preparation method thereof. The water glass-based multiple-effect wood adhesive comprises the following materials by weight parts: 100 parts of water glass, 10-20 parts of ammonium salt modified acrylate emulsion, 4-8 parts of magnesium myristate, 1-2 parts of a silane coupling agent, 5-10 parts of tetrapod-like zinc oxide whiskers, 1-3 parts of xanthan gum, 3-8 parts of silicon dioxide coated ammonium polyphosphate, 3-5 parts of molybdenum oxide, 10-30 parts of water, and 6-12 parts of silica micro-powder. The preparation method comprises the two steps: preparation of silicon dioxide coated ammonium polyphosphate and preparation of the water glass-based adhesive. The water glass-based multiple-effect wood adhesive has environment-friendly and non-poisonous effects, and has the functions of inflaming retarding, smoke suppression, bacteria prevention, sound absorption, corrosion prevention, water proofing and the like; the preparation method is simple and convenient, and is easy in industrialization.

Description

Technical field [0001] The invention relates to the field of wood adhesives, in particular to a water glass-based multi-effect wood adhesive and a preparation method thereof. Background technique [0002] Traditional wood adhesives usually only have the function of bonding. As a result, the preparation of functionalized wood composite materials often requires multiple treatments such as flame retardant and anticorrosion on the wood first, which is cumbersome and weak in effect. The increasing development of the modern wood-based panel industry has made it more and more demanding for adhesives. In addition to high bonding properties, multi-effect wood adhesives with aldehyde-free, flame-retardant, antibacterial, and anti-corrosion properties are receiving more Pay more attention. Summary of the invention [0003] The technical problem solved by the present invention is to provide a water glass-based multi-effect wood adhesive to solve the above-mentioned disadvantages in the backg...
