Problems solved by technology

During production, formaldehyde has a strong pungent smell, is poisonous and has a certain degree of easy to ethylene violence. Because of the presence of free formaldehyde in its finished products, it is very harmful to the health of production and construction personnel.
At the same time, the formaldehyde contained in construction glue will aggravate pollution and bring pungent smell. Its release period is generally 3-15 years, and the harm to human body is long-term, latent and hidden.

Abstract

The invention provides a joint adhesive for adhering the joint of a door / window profile and a preparation method of the joint adhesive. The joint adhesive is prepared from the following raw materials in parts by weight: 6-8 parts of sodium based bentonite, 1-3 parts of borax, 5-7 parts of sodium silicate, 3-5 parts of polyving alcohol, 2.5-5 parts of milled wood lignin, 4-6 parts of oxalic acid and 800-900 parts of water. The preparation method comprises the following steps: preparing the raw materials according to the formula; adding water into a reaction kettle, and heating to be 70 DEG C; adding polyving alcohol in a slow flowing mode, stirring, and heating to dissolve the materials until no granules are retained; cooling to 40-45 DEG C, slowly adding sodium based bentonite, borax, sodium silicate, milled wood lignin and oxalic acid into the reaction kettle when continuously stirring, sufficiently stirring and mixing, further heating to be 65-70 DEG C, after polymerization reaction is completed, heating to be 80-90 DEG C, and stopping heating; after 10-20 minutes after the polymerization reaction, cooling to be less than 50 DEG C; step 6, sampling, testing the viscosity, the pH value and the solid content, and after the indexes are all qualified, cooling and packaging. The joint adhesive is high in adhesion property, free of formaldehyde, free of toxicity, free of environment pollution, and low in cost.

Description

technical field [0001] The invention relates to the field of construction adhesives, in particular to a joint adhesive used for joint bonding of door and window profiles and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, the demand for building adhesives in the construction and decoration market is increasing, and residential environmental protection has also become the focus of attention. The main sources of indoor formaldehyde are the adhesives used in interior decoration, the formaldehyde contained in the glue used in furniture, and the joint glue used in door and window building materials. Glue is a common raw material in industry, but most of its manufacturing raw materials contain formaldehyde. For example, the traditional 107 glue is produced by the condensation reaction of polyvinyl alcohol and formaldehyde. During production, formaldehyde has a strong pungent smell, is poisonous and has a certain degre...
