Embodiment Construction

[0037] Crush the diatomite through a 20-30 mesh sieve, and dry it in an oven at a temperature of 60-80°C to a constant weight to obtain dry diatomite; crush the rock salt ore soil through a 20-30 mesh sieve, and place it in Dry in an oven at a temperature of 60-80°C to constant weight to obtain dry rock-salt ore soil; stir and shear the dry rock-salt ore soil at a temperature of 800-850°C and a stirring speed of 1000-2000r / min for 20-30min, press Add dry diatomaceous earth at a mass ratio of 1:2, continue stirring and shearing for 1 to 2 hours to obtain a mixture; place the mixture on a flat vulcanizing machine, and heat press at a temperature of 160 to 180°C and a pressure of 1 to 5 MPa for 5 to 10 minutes. Cool to room temperature to obtain a green body, crush and grind the green body, and pass through a 20-30 mesh sieve to obtain a precursor; mix gelatin and deionized water at a mass ratio of 1:40, and keep warm at a temperature of 40-50°C for 20 ~30min, to get a mixture, a...

Abstract

The invention relates to a preparation method of a wood treating agent with a formaldehyde adsorption function, and belongs to the technical field of wood treating agents. According to the method, rock salt ores are intercalated into diatomite in a melt intercalation manner to serve as a body, photosynthetic bacteria are embedded by gelatin to serve as fillers, epoxy resin serves as a solvent, andthe wood treating agent is prepared. The surface of wood is coated with the wood treating agent, the wood is taken out and cured, the wood treated by the wood treating agent has good formaldehyde removal effects, the rock salt ores can release negative ions at the temperature of 30 DEG C, so that the formaldehyde is decomposed into carbon dioxide and water, the air negative ions can automaticallycapture harmful substances in the air, the harmful substances such as falling dust and floating dust in the air can be removed, the air negative ions and decoration pollutants such as formaldehyde, benzene and TVOC (total volatile organic compounds) in the air can be reacted, the decoration pollutants are decomposed into carbon dioxide and water, and the ecological air negative ions are small inparticle diameter, high in activity and far in migration distance, so that no-dead-angle and no-residue removing of the formaldehyde is achieved.

Description

technical field [0001] The invention relates to a preparation method of a wood treatment agent with the function of absorbing formaldehyde, and belongs to the technical field of wood treatment agents. Background technique [0002] Wood and its products are widely used in interior decoration, furniture manufacturing, house construction and exterior decoration, but they have problems of shrinkage and swelling when wet, and poor dimensional stability, which affects the service life and use of its products. How to improve dimensional stability has become a widely concerned issue in the wood processing industry. [0003] Cotton fiber is widely used in textile production. The main component of cotton fiber is cellulose, which has strong hygroscopicity and poor dimensional stability. The garments and other products made of it have poor shape retention, are easy to wrinkle and deform, and affect the use of the product. Therefore, how to improve the dimensional stability of cotton p...
