Problems solved by technology

When the two-component glue is used, it needs to be temporarily blended in a specific proportion and stirred evenly, which leads to an extra process, increases the cost of use, and is easy to mix unevenly, and gel appears during use. In addition, The storage time of the stirred glue is also relatively short (2 hours / about 25°C)

Abstract

The invention relates to a one-component laminating glue which comprises the following components in parts by weight: 900 to 945 parts of intermediate material, 25 to 30 parts of polyvinyl alcohol aqueous solution PVA-H2O with the weight percent concentration of 17%, 10 to 15 parts of AlCl3, 0.5 to 1.2 parts of mineral oil defoamer 691, 12 to 18 parts of multifunctional additive DB and 8 to 12 parts of plasticizer DPGDB (Dipropylene Glycol Dibenzoate), wherein the one-component laminating glue is formed by mixing all the components. The one-component laminating glue is very convenient to use, rapid in construction speed and low in cost. In addition, for the one-component laminating glue, the quality is further guaranteed; the heat-resistant performance is improved obviously; the service life and the open period are prolonged; and the one-component laminating glue generates little pollution to the environment.

Description

technical field [0001] The invention relates to a one-component puzzle glue. Background technique [0002] Panel glue refers to the adhesive used for splicing glulam and other wood products, and is suitable for panel bonding of non-structural materials and glulam for structural materials. At present, two-component splicing glue is commonly used in China. Two-component splicing glue means that in addition to glue, a curing agent is required to be used together. , to adjust to the appropriate ratio. When the two-component glue is used, it needs to be temporarily blended in a specific proportion and stirred evenly, which leads to an extra process, increases the cost of use, and is easy to mix unevenly, and gel appears during use. In addition, The storage time of the stirred glue is also relatively short (2 hours / 25°C or so). Contents of the invention [0003] In order to solve the above technical problems, the purpose of the present invention is to provide a kind of very c...
