Problems solved by technology

This kind of imposition glue is not only expensive, but because it is not a special adhesive developed for the production of bamboo flooring, there are problems such as high viscosity of the adhesive, poor fluidity, difficulty in hand brushing and machine rolling; short active period, and poor application. Convenience; aging time is short, affecting production efficiency and other disadvantages
Due to the above reasons, the grade of the bamboo floor made is not high, and the qualified rate of meeting the European E0 standard and the Japanese environmental protection product standard is low

Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the examples, but not as the basis for any limitation of the present invention.

[0029] Example. Taking the main agent of 1000kg of bamboo floor adhesive as an example, prepare the following raw materials: 95kg of polyol, 2kg of emulsifier, 16kg of isocyanate, 200kg of acrylic acid emulsion and 2kg of preservative, and the rest is water; prepare according to the following steps.

[0030] A. Add the polyol into water and heat it to no more than 97 degrees Celsius to stir and dissolve, then lower it to room temperature and add an emulsifier, stir evenly to fully dissolve the polyol, and obtain product A;

[0031] B. In the state of stirring, add isocyanate and acrylic acid emulsion to product A dropwise, and get product B after stirring evenly;

[0032] C. Add preservatives to product B, mix well to get the finished product.

[0033] The finished product is the main agent, and isocyanat...

Abstract

The invention discloses a bamboo floor adhesive and a preparation method thereof. The host crystal of the adhesive in 1,000 weight portions is produced from the following raw materials: 80 to 120 portions of polyol, 1 to 3 portions of an emulsifier, 10 to 20 portions of carbimide, 150 to 250 portions of acrylic latex, 1 to 4 portions of a preservative and sufficient water. The polyol and the emulsifier are heated, are stirred, are added with the carbimide and the acrylic latex and are added with the preservative to prepare the bamboo floor adhesive. The bamboo floor adhesive has the advantages that the product is easy to produce and has low production cost; the adhesive has suitable viscosity and fluidity, convenient hand brushing and machine rolling, long activity period of the product, long aging time, convenient use and high production efficiency; and 100 percent of the manufactured bamboo floor can reach European EO standard and Japanese environment-friendly products standard.

Description

technical field [0001] The invention relates to an adhesive for floor production, especially an adhesive for bamboo floor production. Background technique [0002] At present, there is no special adhesive for bamboo flooring production on the market. Bamboo floor manufacturers generally use imported wood imposition glue for wood floor production as the bamboo floor adhesive in order to produce bamboo floors with a formaldehyde content that does not exceed the standard. This kind of imposition glue is not only expensive, but because it is not a special adhesive developed for the production of bamboo flooring, there are problems such as high viscosity of the adhesive, poor fluidity, difficulty in hand brushing and machine rolling; short active period, and poor application. Convenience; aging time is short, affecting production efficiency and other shortcomings. Due to the above reasons, the grade of the bamboo floor made is not high, and the qualified rate of meeting the Eur...
