Description
Technical Field
The invention relates to the technical field of furan resin production, in particular to a solvent for removing a furan resin heating curing product by a hydrogen peroxide oxidation method.
Background
The furan resin has the characteristics of high normal temperature strength, good toughness and low toxicity, and the raw materials are easy to obtain and low in price, so that the furan resin is one of the resins with the largest application amount. One of the normal detection indexes of the furan resin is to determine the total moisture in the furan resin, the determination method of the moisture is a distillation method, in the daily detection process, after the furan resin is determined in toluene by the distillation method, a layer of thick byproduct is attached to the wall of a container, the byproduct is a furan resin cured product, the product is cured into a macromolecular product by heating, the macromolecular product is insoluble in acid and alkali and a general organic solvent, and the general solvent does not have enough dissolving capacity to remove the cured product. At present, the method for removing furan resin heated and cured products is to carry out carbonization at high temperature, and the temperature can be carbonized only when reaching more than 300 ℃, waste gases such as carbon dioxide and nitrogen oxide can be generated in the process, the environment is polluted, the service life of a container can be reduced by frequently using high-temperature carbonization, the economic expenditure is increased, and the danger coefficient of a high-temperature furnace is large.
Disclosure of Invention
In view of the above technical problems, the invention provides a solvent for removing a furan resin heated and cured product by a hydrogen peroxide oxidation method, which solves the problems of time consumption, resource waste and poor safety in the prior art for removing the furan resin heated and cured product, can rapidly and thoroughly remove the cured product at normal temperature, ensures the cleanness of a container, does not generate waste gas, can be recycled, and greatly saves the cost.
In order to achieve the purpose, the technical scheme adopted by the invention is as follows:
a solvent for removing furan resin heated and solidified products by a hydrogen peroxide oxidation method is composed of the following raw materials in parts by weight:
40-50 parts of water, 40-50 parts of hydrogen peroxide and 5-10 parts of an organic mixed solvent, wherein the organic mixed solvent consists of toluene, acetone and dichloromethane.
Preferably, the mass ratio of the toluene to the acetone to the dichloromethane is 1:1: 5.
Preferably, the solvent for removing the furan resin thermal curing product by the hydrogen peroxide oxidation method is composed of the following raw materials in parts by weight:
42-47 parts of water, 43-48 parts of hydrogen peroxide and 7-9 parts of organic mixed solvent.
Preferably, the solvent for removing the furan resin thermal curing product by the hydrogen peroxide oxidation method is composed of the following raw materials in parts by weight:
44 parts of water, 45 parts of hydrogen peroxide and 8 parts of organic mixed solvent.
Preferably, the solvent for removing the furan resin thermal curing product by the hydrogen peroxide oxidation method is used under the conditions of normal temperature and illumination.
The beneficial effects of the invention are as follows:
1. the formula solvent developed by the invention overcomes the technical defect that the heated cured product is not easy to remove in the process of measuring the moisture by a furan resin distillation method in daily experiments, can quickly and thoroughly remove the cured product at normal temperature, and ensures the cleanness of a container;
2. according to the invention, under the illumination condition, the hydrogen peroxide is subjected to oxidative decomposition under the illumination condition, so that the cured product can be changed into a small molecular substance, the small molecular substance is dissolved by the organic solvent, the reaction speed of the hydrogen peroxide is accelerated through illumination, and finally the dissolution of the cured product generated after the furan resin is detected can be accelerated;
3. the method has safe operation environment, only generates oxygen in the reaction process, does not influence the environment, and can recycle the solvent, thereby greatly saving the cost;
4. the organic mixed solvent of the invention selects toluene, acetone and dichloromethane, because toluene and acetone basically do not have redox reaction under hydrogen peroxide and normal temperature, and acetone can be dissolved in water and various organic matters, while dichloromethane is a low boiling point solvent, is nonflammable, has good safety and can be mutually dissolved with various solvents, the three organic solvents have lower density than hydrogen peroxide, and can be well dissolved when small molecular resin which is not oxidized in the future floats to the upper layer of the hydrogen peroxide.
