Embodiment 1

[0013] A composite wood modifier whose components are proportioned by mass percentage: nano calcium carbonate 15%, zinc borate 8%, amidine urea phosphate 10%, N-hydroxyethyl ethylamine triacetic acid 8%, Sodium borate 10%, chlorothalonil 8%, didecyl dimethyl ammonium chloride 5%, sodium lauryl sulfate 1%, water 20%, silica sol 15%, the nano calcium carbonate is the particle size In the light calcium carbonate nanoparticles of 1-100 nm, the silica content in the silica sol accounts for 25wt%-30wt%.

[0014] Preparation method: (1), weigh each component according to the weight ratio; (2), add nano calcium carbonate and sodium lauryl sulfate into a mixer, mix well, then add water, and heat up to 50℃~80 ℃, stir at a high speed of not less than 6000r / min for 20-50min, then ultrasonically disperse for 15-30min, then add zinc borate, amidine urea phosphate, N-hydroxyethyl ethylamine triacetic acid, sodium octaborate and nanometer Silica sol, stir at a low speed of 80-150r / minr for 10-1...

Embodiment 2

[0016] A composite wood modifier whose components are proportioned by mass percentage: nano calcium carbonate 10%, zinc borate 5%, amidino urea phosphate 5%, N-hydroxyethyl ethylamine triacetic acid 5%, eight Sodium borate 5%, chlorothalonil 5%, didecyl dimethyl ammonium chloride 4%, sodium lauryl sulfate 1%, water 40%, silica sol 20%, the nano calcium carbonate is the particle size In the light calcium carbonate nanoparticles of 1-100 nm, the silica content in the silica sol accounts for 25wt%-30wt%.

[0017] The preparation method is the same as in Example 1.

Abstract

The invention discloses a composite wood modifier, the composite wood modifier comprises the following components by mass: 10%-15% of nano calcium carbonate, 5%-8% of zinc borate, 5%-10% of amidinourea phosphate, 5%-8% of N-hydroxyethyl ethylamine triacetic acid, 5%-10% of sodium octoborate, 5%-8% of chlorothalonil, 3%-5% of didecyldimethylammonium chloride, 1%-2% of lauryl sodium sulfate, 20%-40% of water and 15%-20% of silica sol, and the nano calcium carbonate is light calcium carbonate nanoparticles with the particle diameter of 1 to 100 nm. The beneficial effects are that the composite wood modifier has flame retardant, anti-corrosion, enhancing and other functions, and has the advantages of good permeability, strong resistance to erosion, low cost and convenient use to wood treatment.

Description

Technical field [0001] The invention relates to the technical field of wood treatment agents, in particular to a composite wood modifier. Background technique [0002] Wood is a natural organic material with obvious biological characteristics. It is easy to be attacked by bacteria, insects, marine borer insects and other organisms. It is also easy to burn and absorb moisture, which will greatly affect its application effect and application field. Therefore, it is usually necessary to carry out anti-corrosion and flame-retardant modification treatments before wood is used to better improve the performance of wood. At present, various wood treatment agents have appeared on the market, such as preservatives, flame retardants, etc. However, due to the different formulations of each treatment agent, the wood treatment effect is also different, and the effect is still far from the expected effect. There are gaps. Summary of the invention [0003] The purpose of the present invention i...
