preparation example 1

[0070] Preparation Example 1: Preparation of Urea-Formaldehyde Resin 1

[0071] 340 g of formaldehyde (Formalin: Formaline (37%)) and 126 g of urea (Urea) were added to a 4-necked synthesis flask equipped with a thermometer and a stirring device, and stirred at room temperature while blowing nitrogen gas. Then, after confirming that the liquid phase was clear, 0.8 g of sodium hydroxide (20% aqueous solution) was added. Then, after confirming that the pH reached the level of 8-9, the temperature was gradually raised to 80°C. After maintaining at this temperature for 2 hours, the temperature was lowered to room temperature, and then diluted with 232 g of distilled water. As a result, a urea-formaldehyde resin having a solid content of 36% and a pH of 8.26 was obtained. Here, it was confirmed that the total molar equivalent ratio of formaldehyde to the urea (Urea) was 2:1.

[0072] Preparation Example 2: Preparation of Urea-Formaldehyde Resin 2

[0073] 511 g of formaldehyde (formalin (37%)) and 126 g of urea (Urea) were added to a 4-neck synthesis flask equipped with a thermometer and a stirring device, and stirred at room temperature while blowing nitrogen gas. Then, after confirming that the liquid phase was clean, 1.0 g of sodium hydroxide (20% aqueous solution) was added. Then, after confirming that the pH reached the level of 8-9, the temperature was gradually raised to 80°C. After maintaining at this temperature for 2 hours, the temperature was lowered to room temperature, and then diluted with 238 g of distilled water. As a result, a urea-formaldehyde resin having a solid content of 36% and a pH of 8.31 was obtained. Here, it was confirmed that the total molar equivalent ratio of formaldehyde to the urea was 3:1.

Embodiment 1

[0075] Add 350kg of the urea-formaldehyde resin composition prepared in Preparation Example 1, 310kg of molasses (Molasses (80%)), 30kg of citric acid (Citricacid (98%)), 3800kg of distilled water, 2kg of Silicone water repellent (SI1420Z-KCC) and 3 kg of dustproof oil (DustOil-GoviGaro217S) were stirred for 30 minutes with a mixer to prepare an adhesive composition. It was confirmed that the solid content of the prepared adhesive was about 9%.

Abstract

The present invention relates to a binder composition and a binding method using the same, and can provide a binding method of a fibrous material using the binder composition. The binder composition according to the present invention little contains a harmful material such as formaldehyde and has economical curing conditions, and can realize high water resistance and surface hardness of processed products through the binding method using the binder composition.

Description

technical field [0001] The present invention relates to an adhesive composition and an adhesive method using the same. Background technique [0002] Glass wool used as a non-combustible heat insulating material is a material used to suppress the flow of heat from a high temperature to a low temperature, and it is a heat insulating material whose thermal conductivity at normal temperature is approximately 0.1Kcal / mh°C or less. As far as glass wool is concerned, 6 kinds of glass raw materials other than silica sand are melted at high temperature and fiberized by high-speed rotating force, and then formed into man-made mineral fiber (ManMadeMineralFiber: MMMF) with a certain shape. It is a product that continuously forms pores and is used as thermal insulation, heat insulation, and sound-absorbing materials. It is a thermal-insulation, heat-insulation, and sound-absorbing material that is formed by spraying thermosetting resin on a fibrous product to form a pad or plate. [00...
