Embodiment Construction

[0014] The present invention will be further described below in conjunction with embodiment:

[0015] A method for manufacturing an environmental-friendly board adhesive, the manufacturing steps are as follows:

[0016] (1) 90 parts by weight of formaldehyde solution with a mass concentration of 15 to 25 wt%, 0.3 to 0.5 parts of an alkaline solution and 0.3 to 0.5 parts of an amino-terminated hyperbranched polymer PAMAM with a mass concentration of 20 to 30 wt%, stirring to obtain the initial mixture;

[0017] (2) Add 2 to 6 parts by weight of hexachlorocyclotriphosphazene to the initial mixture in step (1), raise the temperature to 80°C, when the temperature rises to 85°C, add 20 to 30 parts by weight of melamine, and continue to heat up to 90°C , the reaction gives a preliminary polycondensate;

[0018] (3) adding 30 to 40 parts by weight of melamine to the preliminary polycondensate in step (2), and adding 0.8 to 1.5 parts by weight of p-toluenesulfonamide to obtain a sec...

Abstract

The invention discloses a preparation method of an environment-friendly adhesive for a board, and belongs to the technical field of building materials. The preparation method comprises the following preparation steps of weighing the following components in parts by weight: 90 parts of formaldehyde aqueous solution with a mass concentration of 15wt% to 25wt%, 0.3 to 0.5 part of alkaline matter solution with a mass concentration of 20wt% to 30wt% and 0.3 to 0.5 part of amino-terminated hyperbranched polymer PAMAM (Polyamidoamine) and agitating to obtain an initial mixture; adding 2 to 6 parts byweight of hexachlorocyclotriphosphazene into the initial mixture, raising a temperature to 80 DEG C, adding 20 to 30 parts by weight of melamine when the temperature is raised to 85 DEG C, continuously raising the temperature to 90 DEG C and reacting to obtain a primary condensation polymer; adding 30 to 40 parts by weight of melamine into the primary condensation polymer and adding 0.8 to 1.5 parts by weight of para toluene sulfonamide, so as to obtain a second condensation polymer; adding 20 to 35 parts by weight of urea when the temperature of the second condensation polymer is decreased to 60 DEG C, continuously reacting for 15min to 20min and discharging the adhesive when the temperature is decreased to 50 DEG C. The environment-friendly adhesive not only retains a better flame-retarding effect and has a small formaldehyde emission amount, but also has more stable product quality.

Description

technical field [0001] The invention belongs to the technical field of building materials, and relates to a method for manufacturing an adhesive, in particular to a method for manufacturing an environmentally friendly board adhesive. Background technique [0002] Decorative board is a kind of man-made board. It is a thermosetting laminated plastic made of high-temperature and high-pressure adhesive after chemical treatment with a variety of special papers. The board surface has various wood grains or patterns, bright and flat, bright and beautiful. The walls and roofs of many high-end houses, well-made cabinets, cabinets, tables, beds, workbenches for precision instruments, laboratory test benches, TV sets, radios and other shells of broadcasting and telecommunications equipment, mostly use this new type of material. Decorative plates. [0003] Adhesive is an indispensable material in the preparation of boards. With the prosperity of the economy, vicious fire accidents caus...
