Fireproofing and insect-proofing modifying liquid for collection tools of files and cultural relics and application of modifying liquid

Abstract

The invention provides a fireproofing and insect-proofing modifying liquid for collection tools of files and cultural relics and an application of the modifying liquid. The modifying liquid is composed of a solution A and an alum aqueous solution with a mass fraction of 15%-25%, wherein the solution A is composed of the following components in parts by weight: 1000 parts of water, 8-15 parts of urea, 40-120 parts of sodium tetraborate decahydrate, 5-20 parts of soluble carbonate, 60-140 parts of boric acid, 80-120 parts of sodium octoborate tetrahydrate, 15-35 parts of sodium fluoride, 20-30 parts of silica sol and 5-15 parts of potassium sorbate. The application method of the fireproofing and insect-proofing modifying liquid comprises the steps: soaking wood in water until the moisture content of the wood is above 66%; next, soaking the wood in the solution A, and in the soaking process, applying ultrasonic treatment every four hours; and finally, soaking the wood in the alum solution with the mass fraction of 15%-25%. The modifying liquid provided by the invention is low in price, non-volatile and non-toxic; the wood treated by using the modifying liquid does not generate toxic gases, has a good flame retardant effect, and is resistant to insects and good in leaching resistance; as a result, the wood can be used for fabricating the collection tools of files and cultural relics.

Description

technical field [0001] The invention belongs to the technical field of physical and chemical modification of wood, and in particular relates to a modification liquid for making wooden materials such as archives and cultural relics with fireproof performance, and an application method of the modification liquid. Background technique [0002] At present, the utensils commonly used for archives and cultural relics are mostly made of horse manure paper, kraft paper, or acid-free paper with a single function, bonded with flour paste, or stored in wooden file boxes and file cabinets with no technological content. These cartons and wooden boxes are flammable and prone to insects. In order to prevent fire prevention, archives, libraries, museums and other cultural and museum collection units have invested huge sums of money in improving fire prevention facilities when building their museums. These facilities are all burned with water or CO 2 Fire fighting, lack of proactive preven...

AI Technical Summary

Problems solved by technology

In a national document collection unit in our country, there was an accident where the smoke alarm was falsely reported, causing a large amount of water to pour into the warehouse and destroy the collection.

In order to prevent insects, archives, books, and cultural relics departments generally use chemicals such as camphor and naphthalene for prevention, and toxic drugs such as ethylene oxide and methyl bromide for killing. Although they have a protective effect on cultural relics to a certain extent, these chemical reagents pollute Cultural relics and the working environment are harmful to human health

[0003] At present, there are many reports on wood flame retardant at home and abroad. Among the existing flame retardants, organic flame retardants release a large amount of toxic gases when burned and are expensive; halogenated flame retardants will produce hydrogen halide and other gases when burned. It will form dense smoke and cause fatal damage to the human body; resin-type flame retardants have unsatisfactory flame retardant effects, poor permeability, and darker wood color; inorganic flame retardants are characterized by good flame retardant effects, wide sources, and low prices

At present, the amount of inorganic flame retardants accounts for about 60% of the total demand for flame retardants, but its disadvantage is that it is easy to lose
