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

Embodiment 1

[0019] 1. Soak the wood to be treated in water, and use an ultrasonic wave with a power of 800W for 60 minutes every 4 hours. After the moisture content of the wood reaches more than 66%, take out the wood.

[0020] 2. Add 80g of sodium tetraborate decahydrate, 15g of sodium carbonate, 90g of boric acid, and 100g of sodium octaborate tetrahydrate into 1000g of water, heat and stir at 60-70°C until completely dissolved, then add 25g of silica sol, 12g of urea, and 30g of sodium fluoride , 10g potassium sorbate, keep stirring at constant temperature until the solution is clear and transparent, and prepare solution A; soak wood with a moisture content of more than 66% in solution A, heat to 60°C, and use an ultrasonic wave with a power of 800W every 4 hours 60 minutes, for a total soak time of 48 hours, remove the wood.

[0021] 3. Soak the wood treated by soaking in solution A in step 2 in an aqueous alum solution with a mass fraction of 20%, soak for 40 minutes, take out the wo...

Embodiment 2

[0023] In Example 1, 40g of sodium tetraborate decahydrate, 5g of sodium carbonate, 60g of boric acid, and 80g of sodium octaborate tetrahydrate were added to 1000g of water, heated and stirred at 60-70°C until completely dissolved, then 20g of silica sol, 8g of urea, 15g sodium fluoride, 5g potassium sorbate, keep stirring at constant temperature until the solution is clear and transparent, and prepare solution A. Other steps are identical with embodiment 1.

Embodiment 3

[0025] In Example 1, 120g of sodium tetraborate decahydrate, 20g of sodium carbonate, 140g of boric acid, and 120g of sodium octaborate tetrahydrate were added to 1000g of water, heated and stirred at 60-70°C until completely dissolved, then 30g of silica sol, 15g of urea, 35g of sodium fluoride and 15g of potassium sorbate were stirred at constant temperature until the solution was clear and transparent, and then solution A was prepared. Other steps are identical with embodiment 1.

[0026] In order to prove the beneficial effects of the present invention, the inventor has carried out a large amount of laboratory research tests, and various test conditions are as follows:

[0027] 1. Effect of ultrasonic treatment on water absorption of wood

[0028] According to the method of Example 1, paulownia wood with a size of 34cm×1.9cm×1.0cm was treated, and the mass of paulownia wood was weighed before and after each ultrasonic treatment, and the influence of ultrasonic treatment o...

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...
