Embodiment 1

[0075] The preparation of embodiment 1 urushiol-based phosphorus-containing polymer D1

[0076] Synthesis and Characterization of a1 Urushiol-based Diglycidyl Ethers

[0077] Add 0.3 mol of urushiol and 0.6 mol of epichlorohydrin into a four-neck flask equipped with a stirrer, reflux condenser, thermometer, and dropping funnel, heat up to 55°C, and add 60 ml of 10 mol of / L NaOH solution for 1.5 hours. After the dropwise addition, the temperature was raised to 65° C., and the reaction was carried out at a constant temperature for 5 hours to obtain a mixture containing urushiol bis-shrunk oil ether, water, and sodium chloride. Add xylene and water to the mixture containing urushiol diglycidyl ether, water, and sodium chloride, wash with water, let stand overnight and separate layers, remove the inorganic matter in the water layer, wash repeatedly, and distill under reduced pressure to obtain urushiol-based diglycidol Ether compounds, denoted as r1-1 # .

[0100] The preparation of embodiment 2 urushiol-based phosphorus-containing polymer D2

[0101] Synthesis and Characterization of a2 Urushiol-based Diglycidyl Ethers

[0102] Add 0.3 mol of urushiol and 0.6 mol of epichlorohydrin into a four-necked flask equipped with a stirrer, reflux condenser, thermometer, and dropping funnel, heat up to 55°C, and add 30 ml of 10 mol of / L KOH solution for 2 hours, after the dropwise addition, the temperature was raised to 65°C, and the reaction was carried out at constant temperature for 4 hours to obtain a mixture containing urushiol bis-shrunk oil ether, water, and sodium chloride. Add xylene and water to the mixture containing urushiol diglycidyl ether, water, and sodium chloride, wash with water, let stand overnight and separate layers, remove the inorganic matter in the water layer, wash repeatedly, and distill under reduced pressure to obtain urushiol-based diglycidol Ether compounds, denoted as r2-1 # .

Embodiment 3

[0119] Embodiment 3 Preparation of Flame Retardant Pressure Sensitive Adhesive 1#

[0120] The preparation method of the flame-retardant pressure-sensitive adhesive is: mix 60.0g of urushiol-based phosphorus-containing polymer D1, 1.0g of curing agent TDI, and 39.0g of ethyl acetate under mechanical stirring to obtain a flame-retardant pressure-sensitive adhesive. Glue, recorded as sample 1#.

[0121] In sample 1#, the mass content of each component is:

[0122] Urushiol-based phosphorus-containing polymer D1: 60%;

[0123] Curing agent TDI: 1%;

[0124] Ethyl acetate: 39%.

Abstract

The invention discloses a flame-retardant pressure sensitive adhesive and an application thereof. The flame-retardant pressure sensitive adhesive includes a urushiol-based phosphorus-containing polymer, a curing agent, and an organic solvent. The flame-retardant pressure sensitive adhesive contains a recyclable natural product urushiol unit, and the long-side unsaturated chain of the recyclable natural product urushiol unit is prone to crosslink and react, so the flame-retardant pressure sensitive adhesive has good bonding performance and an excellent flame retarding property; and a preparation method of the adhesive has the advantages of simplicity in operation, and wide sources of raw materials.

Description

technical field [0001] The application relates to a flame-retardant pressure-sensitive adhesive and its application, belonging to the field of chemical materials. Background technique [0002] Pressure-sensitive adhesives are used in all areas of people's lives, such as labels, packaging, surface protection films, book bindings, tapes, etc. Acrylic pressure-sensitive adhesive has the fastest development in the pressure-sensitive adhesive industry in recent years because of its excellent pressure-sensitive performance, anti-aging and solvent resistance. At present, the output of acrylic pressure-sensitive adhesives has accounted for more than 90% of the output of the entire pressure-sensitive adhesive field. The development of acrylic pressure-sensitive adhesives has greatly facilitated people's lives. Because acrylate materials have flammable hydrocarbon chain segments in their structure, they are easy to burn and difficult to self-extinguish in case of fire. When burning, ...
