Embodiment 8

[0105] Glass wool is used as the inorganic fiber. The following adhesive is used as the adhesive, and the adhesive is 100 parts by mass of a mixture of 70:30 mixture of resole phenolic resin and urea resin, adding 0.2 mass part of aminosilane (aminosilane) and 1 mass part Obtained from ammonium sulfate which becomes a curing catalyst. Adhesive is given to glass wool so that the amount of adhesive attached is 9.5% by mass based on the mass of the inorganic fiber heat-insulating and sound-absorbing material to obtain a thickness of 25 mm and a density of 96 kg / m. 3 Inorganic fiber insulation and sound-absorbing materials.

[0106] The aldehyde scavenger of Example 1 was applied by the spraying method so that the adhesion amount thereof was 4.8 g / m in terms of solid components relative to the surface area of ​​the inorganic fiber heat-insulating and sound-absorbing material obtained by the above-mentioned method. 3 , Obtain the building material of embodiment 8.

Embodiment 9～12

[0108] In Example 8, except having used the aldehyde scavenger of Examples 2-5 instead of the aldehyde scavenger of Example 1, it carried out similarly to Example 8, and obtained the building material of Examples 9-12.

Embodiment 13

[0128] Glass wool is used as the inorganic fiber. The following adhesive is used as the adhesive, and the adhesive is 100 parts by mass of a mixture of 70:30 mixture of resole phenolic resin and urea resin, adding 0.2 mass part of aminosilane (aminosilane) and 1 mass part Obtained from ammonium sulfate which becomes a curing catalyst. Adhesive is given to glass wool so that the amount of adhesive attached is 9.5% by mass based on the mass of the inorganic fiber heat-insulating and sound-absorbing material to obtain a thickness of 50mm and a density of 32kg / m 3 Inorganic fiber insulation and sound-absorbing materials.

[0129] The aldehyde scavenger of Example 1 was applied by spraying so that the amount of adhesion relative to the surface area of ​​the obtained inorganic fiber heat-insulating and sound-absorbing material was 4.8 g / m in terms of solid components 3 , followed by 30g / m in terms of solid components 2 The amount of the chloropropylene rubber (chrolopropylene rub...

Abstract

The invention provides a water system aldehyde catching agent capable of maintaining excellent aldehyde catching effect for a long time and construction material with aldehydes releasing inhibited. The principal components of the agent in the invention is adhesive of aldehyde condensative thermosetting resin; the construction material obtained by forming and solidifying has the adhesion of aldehyde catching agent which consists of the water based composition including polyamide, bisulfite and carbamide in 0.05-10g / m2 measured in solid state component relative to the surface area of the construction material.

Description

technical field [0001] The present invention relates to an aldehyde scavenger having an excellent aldehyde scavenging effect over a long period of time, and a building material in which the release of aldehydes is suppressed. Background technique [0002] In recent years, from the viewpoint of energy saving, high heat insulation and high airtightness of residential buildings are being recommended. On the other hand, volatile organic compounds (VOCs) released from organic materials used in building materials are continuously degrading the living environment. [0003] In particular, there is a large amount of aldehyde-condensable thermosetting resins used in construction materials such as plywood for structures, furniture, coatings for building materials, adhesives, and inorganic fiber heat-insulating and sound-absorbing materials. )” in the case of formaldehyde as the causative substance. [0004] Therefore, in order to maintain a comfortable residential environment, it is ...
