Problems solved by technology

Most of the flame retardant impregnating glue flame retardants used on wooden materials contain materials such as borax, such as the impregnated adhesive paper disclosed in patent CN 1898333 A and the wood flame retardant impregnating glue disclosed in CN 101462287 B, while the key components of fire retardant such as boron infiltrate Depth to wood is less than ideal
In the dipping process, the compatibility of flame retardants and resins is poor, and it is easy to affect its curing time
In addition, most of the curing agents used in impregnating glue are imported products, and the production cost is high

Embodiment 1

[0030] A flame-retardant impregnating glue prepared by parts by weight from the components described in Table 1:

[0031] Table 1

[0032]

[0033] Among them, melamine-formaldehyde resin is generally weakly alkaline, and as the amount of free formaldehyde increases, the curing time will be accelerated. In this implementation, the mass fraction of formaldehyde in the melamine formaldehyde resin is 4%. The solid content and viscosity of the melamine formaldehyde resin will affect the system stability of the impregnating glue and the permeability of the functional components. In this embodiment, the solid content of the formaldehyde resin is 56%, and the viscosity is 17 seconds.

[0034] Wherein, the composite flame retardant powder is made of 25 parts by weight of ammonium polyphosphate, 5 parts by weight of small particle urea, 40 parts by weight of Al(OH) 3 and 30 parts by weight of Mg(OH) 2 Mix well.

[0035] Among them, the curing agent is prepared by dissolving 20 p...

Embodiment 2

[0038] A flame-retardant impregnating glue, which is uniformly mixed by stirring and mixing the components shown in Table 2 in parts by weight:

[0039] Table 2

[0040]

[0041] Wherein, the solid content of the melamine formaldehyde resin is 55%, the viscosity is 17 seconds, and the mass fraction of free formaldehyde is 2%;

[0042] The composite flame retardant powder is mixed evenly by 22 parts by weight of ammonium polyphosphate and 8 parts by weight of small particle urea, and then added 35 parts by weight of Al(OH) 3 and 35 parts by weight of Mg(OH) 2 production. Small granular urea is urea with a nitrogen content of 46.4% and a particle size of 0.85-2.80 mm.

[0043] Wherein the penetrating agent is selected from alkylate penetrating agents, the release agent is selected from silicone release agents, the defoamer is selected from silicone defoamers, and the dust remover is selected from stearic acid amide dust removers.

[0044] The curing agent is prepared by d...

Embodiment 3

[0046] A flame-retardant impregnating glue, which is formed by stirring and mixing the components shown in Table 3 in parts by weight:

[0047] table 3

[0048]

[0049]During the mixing process, first take 40 parts of composite flame retardant, add 12 parts by weight of water to mix and dissolve, mix with 55 parts by weight of melamine formaldehyde resin, add 0.3 parts by weight of penetrating agent, 0.05 parts by weight of release agent, 0.03 parts by weight of Part of dust remover, 0.05 part by weight of defoamer, and then add 0.5 part by weight of polyamide wax water-based anti-settling agent as anti-settling agent, stir and mix evenly to obtain flame-retardant adhesive.

[0050] The polyamide wax water-based anti-settling agent model Disparon 5501.

[0051] Wherein, the solid content of the melamine formaldehyde resin is 52%, the viscosity is 15 seconds, and the mass fraction of free formaldehyde is 5%.

[0052] Wherein, the composite flame retardant powder is made b...

Abstract

The invention relates to a flame-retardant impregnating adhesive and an application of the impregnating adhesive in preparation of a flame-retardant finishing decorative plate. The flame-retardant impregnating adhesive comprises the following components in parts by weight: 45-55 parts of melamine formaldehyde resin, 0.2-0.3 parts of curing agent, 30-40 parts of composite flame-retardant powder, 0.2-0.5 parts of assistant and 10-12 parts of water, wherein the composite flame-retardant powder is prepared from magnesium hydrate, aluminum hydroxide, ammonium polyphosphate and small-particle urea; and the curing agent is prepared from p-toluenesulfonic acid, morpholine and water. The flame-retardant impregnating adhesive is good in system compatibility, and the possibility of bubbling, thickening and the like is low. The flame-retardant finishing decorative plate prepared after an impregnating adhesive tape is prepared via the flame-retardant impregnating adhesive is low in production cost and good in flame-retardant effect.

Description

technical field [0001] The invention relates to an adhesive and its application, in particular to a flame-retardant impregnated adhesive and its application. Background technique [0002] The country has national mandatory standards for interior decoration materials in public places, which are required to meet Class B or above in the classification of combustion performance of building materials and products (GB 8624-2006). Facing decorative panels are mainly composed of wood-based panels and decorative panels. Usually, wood-based panels cannot reach the B-level classification of building materials and product combustion performance. The base paper of decorative panels is a combustible base paper. Amino resin can play a certain flame retardant effect, but not many can reach the B grade of the combustion performance classification of building materials and products. Due to the lack of strict implementation in practical applications, fire accidents emerge in endlessly. At pr...
