[0044] (1) Preparation of self-made metal antifungal agent:

[0045] Mix ethyl orthosilicate, absolute ethanol and deionized water at a mass ratio of 3:5:10 and put them into a beaker, then move the beaker into a water bath, heat up to 50-60°C, and add Adjust the pH to 3-4 with hydrochloric acid, and stir for 30-40 minutes;

[0046] After the above stirring reaction is completed, continue to stir at 40-50°C, and slowly add copper chloride solution and orthosilicate solution with a concentration of 1mol / L 2 to 3 times the mass of ethyl orthosilicate to the beaker under stirring. 3-Aminopropyltriethoxysilane with 50% ethyl ester mass, continuously stirred and reacted for 3-5 hours to obtain a self-made metal antifungal agent;

[0047] (2) Preparation of pre-emulsion:

[0048] In parts by weight, weigh 10-12 parts of the above self-made metal antifungal agent, 10-15 parts of tetraethyl orthosilicate, 5-8 parts of propylene glycol, 15-16 parts of n-butanol and 1-2 parts of hard ...

Abstract

The invention relates to ancient architecture timber structure waterproof anticorrosive paint and a preparation method thereof, and belongs to the technical field of timber protection. A timber impregnating compound is prepared from a mixed solution of triethylamine trihydrogen fluoride and ammonium hexafluorophosphate; ionization ions in the mixed solution of triethylamine trihydrofluoride and ammonium hexafluorophosphate can penetrate into an amorphous region of wood fibers to access to the outer surface of a crystallization zone; by destroying hydrogen bond bonding between water and cellulose, swelling in a cellulose amorphous region occurs, which further facilitates permeation of the waterproof anticorrosive paint; meanwhile, tetraethoxysilane and copper ions are compounded to preparethe silica gel immobilized copper mildew preventive, and after the coating permeates into the wood, the silica gel can firmly fix metal copper ions in the timber structure material, the protective performance of the ancient architecture timber structure to mold is improved through the good mold resistance of the metal copper ions, and the waterproof performance of the ancient architecture timber structure is also remarkably improved after the paint is used. Therefore, the paint of the invention has wide application prospects.

Description

technical field [0001] The invention relates to a waterproof and anti-corrosion paint for wooden structures of ancient buildings and a preparation method thereof, belonging to the technical field of wood protection. Background technique [0002] China is a large land and sea country, with a coastline length of 18,000 kilometers, ranking fourth in the world; along the coastline of the mainland, there are many bays and port cities, from north to south: Dalian, Qinhuangdao, Tianjin, Yantai, Qingdao, Lianyungang, Nantong , Shanghai, Ningbo, Wenzhou, Fuzhou, Xiamen, Guangzhou, Zhanjiang, Beihai, etc. In these cities, there are wooden ancient building groups of different ages. They are the country's non-renewable and precious historical heritage, an important symbol of national civilization, and a precious wealth of the nation. Strong winds in these coastal cities will bring the salt spray in the sea to the land, forming a salt spray corrosive environment. [0003] Therefore, it...
