Abstract

PURPOSE: A building material using papermaking sludge is provided which can be used as a heat shield material, a protection material against insects, a waterproof material. CONSTITUTION: The heat shield material and the protection material against insects are produced by a process comprising the steps of: pulverizing a waste paper to make a pulp paper wadding; mixing the paper wadding with the papermaking sludge; adding an urea, a formalin, a sodium hydroxide, a fire extinguisher, an antibacterial drug, deodorizer and then pressing the product. The waterproof material is produced by a process comprising the steps of: mixing the paper wadding with the papermaking sludge; adding an emulsifying agent, a dissolved bitumen in waste lubricant, sand, silica sand and then pressing the product.

Description

Manufacturing building materials with the utilization of paper sludge}

Conventionally, the use of papermaking sludge as a fuel has been developed. However, the technology using papermaking paper as a fuel has been developed, but it has not solved problems such as odor, and various kinds of living containers have been used, but have not been put into practical use.

In the present invention, in order to increase the filling effect of paper sludge and increase the adsorption of water, the waste paper is pulverized to make pulp-type cotton wool, mixed with paper sludge, and urea, formarin and caustic soda are synthesized. The urea resin was used to make building insulation with high filling and thermal insulation.

In addition, in order to enhance the semi-permanent antimicrobial effect on the paper paper slurries, silver was synthesized by organic and inorganic materials to make silver solution, and an inorganic antimicrobial agent having high antimicrobial activity was used, and a zeolite having a high deodorizing effect was also synthesized and emulsified to increase the flame retardant effect. Chlorinated paraffin phosphate was used to increase the semi-permanent flame retardant effect.

As described above, the pulp-type paper wool using waste paper was synthesized to increase the filling effect. Also, the flame retardant and the silver ion antimicrobial agent were used to have a semi-permanent antibacterial effect as well as a flame retardant effect.

In addition, by reducing the amount of solution of urea, formarin, caustic soda and so on, the urea resin was reduced to compress the heat to increase the thermal insulation effect and the filling effect was the same as Styropol.

In addition, in order to make the papermaking sludge with the pulp-type cotton of the lung paper, an emulsifier is synthesized in the papermaking clutch to make a slate-type roofing and waterproofing agent, and the bone talcum is dissolved in the waste lubricating oil to synthesize a part of chlorinated paraffin and a part of rosin so that there is adhesion and flameproofing. After compressing by mixing with soft silica sand or silver sand, it can be used to make a thread-type roofing, and if used as semi-solid without roofing to waterproof the roof, a waterproof elasticizer is made.

Example 1

1st process

(Waste paper wool production)

10 kg of waste paper is put in a grinder with a blade and pulverized to form a pulp paper batting.

2nd process

20 kg of paper sludge is mixed with 10 kg of low-step waste paper wool.

3rd process

To prevent flame retardant deodorization, liquefied by mixing 5kg of sodium phosphate 5kg water and liquefied, and 3kg of chloride paraffin was synthesized by mixing 300g of emulsifier and 100g of silver ionic antimicrobial agent, 2 liters of primary sodium chlorate was mixed and 500g of zeolite was synthesized and stirred.

4th process

The waste paper wool and papermaking sludge of the second process are mixed with the synthesized semi-solid sheet and the synthesized chemical of the third process.

5th process

2 kg of urea, 500 g of formalin and 500 g of caustic soda are synthesized, and the pigment is added while synthesizing with the product of the fourth step.

6th process

The product of the fifth process is compressed into a compressor that can adjust the thickness to complete insulation or various product fillers, which are building materials.

Example 2

1st process

Example 1 10 kg of pulp cotton is prepared using the waste paper pulp cotton of the process.

2nd process

20 kg of papermaking slurries are mixed with 10 kg of paper wool to make a semi-solid.

3rd process

1 kg of an emulsifier is synthesized in the semi-solid sludge of the second step.

4th process

For flame retardant treatment, 10 g of emulsifier was added to 2 liters of chlorinated paraffin, 1 liter of water was mixed and emulsified, and 5 kg of sodium phosphate was dissolved in water for synthesis.

5th process

The flame retardant of the fourth process is synthesized with the emulsified semisolid sludge of the third process.

6th process

Dissolve the bone talcum by mixing 5 kg of bone talcum with 6 liters of waste lubricant.

7th process

Synthesis is performed with the flame retardant paper sludge treated in the fifth step and the bone talcum of the sixth step and synthesized by increasing the viscosity with silica sand or silver sand.

8th process

The seventh process is compressed to complete the roofing thread.

9th process

The waterproofing agent uses the product of the sixth process as it is.

The present invention not only uses paper sludge efficiently, but also uses it as a thermal insulation material or insect repellent instead of styropol, so it is economically effective. In addition, the roofing thread has excellent durability, waterproofness and economy. It can also be used semi-permanently.
