Problems solved by technology

[0004] At present, there are still two major technical problems in the backboard adhesive in mineral wool sound-absorbing panels. One is that manufacturers are still using a large amount of urea-formaldehyde resin, which leads to serious excess formaldehyde in mineral wool sound-absorbing panels. As we all know, formaldehyde is a first-class carcinogen , when formaldehyde reaches a certain concentration indoors, people will feel uncomfortable.
Greater than 0.08mg / m 3 The concentration of formaldehyde can cause red eyes. GB / T25998-2010 stipulates that mineral wool sound-absorbing panels need to meet the E1 standard. , because the moisture-proof and anti-sag of the backboard adhesive is not enough, which leads to its failure to be widely used in the south, and its application is greatly restricted. Therefore, it is necessary to further develop a backboard adhesive in a mineral wool sound-absorbing panel Adhesive, which can take into account moisture-proof performance and environmental protection performance, used in mineral wool sound-absorbing panels

Embodiment 1

[0017] Embodiment 1 (preparation of modified acrylic resin)

[0018] Formula: 60 parts of water-soluble acrylic resin, 5 parts of casein, 0.5 part of microcrystalline paraffin, 1 part of sodium benzoate, 2 parts of agar, 0.5 part of silane coupling agent, and 5 parts of water.

[0019] According to the above formula, mix water and water-soluble acrylic resin evenly, add casein at 30-35°C, mix in a high-speed mixer, then adjust the pH to 3-5, add sodium benzoate and agar to it, stir well, and then Add silane coupling agent and microcrystalline paraffin, stir and mix evenly.

Embodiment 2

[0020] Embodiment 2 (preparation of modified acrylic resin)

[0021] Formula: 80 parts of water-soluble acrylic resin, 15 parts of casein, 1 part of microcrystalline paraffin, 2 parts of sodium benzoate, 3 parts of agar, 1.5 parts of silane coupling agent, and 10 parts of water.

[0022] According to the above formula, mix water and water-soluble acrylic resin evenly, add casein at 30-35°C, mix in a high-speed mixer, then adjust the pH to 3-5, add sodium benzoate and agar to it, stir well, and then Add silane coupling agent and microcrystalline paraffin, stir and mix evenly.

Embodiment 3

[0023] Embodiment 3 (research on formula of backboard glue)

[0024] Formula: 20 parts of modified water-soluble acrylic resin, 30 parts of biomass raw material, 30 parts of filler, 1 part of potassium tripolyphosphate, and 20 parts of water.

[0025] The modified water-soluble acrylic resin adopts the product obtained in Example 1. The biomass raw material is glucose syrup. The filler adopts glass microspheres.

Description

technical field [0001] The invention belongs to the technical field of fine chemical products, and in particular relates to a formaldehyde-free bio-based backing glue for a mineral wool sound-absorbing board and a preparation method thereof. Background technique [0002] Mineral wool sound-absorbing board is mainly a kind of building material obtained by pressing and hardening mineral wool, starch and backboard adhesive. Because the average thermal conductivity of mineral wool is small, it is easy to keep warm, and it has sound absorption, non-combustibility, heat insulation, and light weight. It is an indoor ceiling decoration material that integrates the advantages of all ceiling materials and is widely used in various building ceilings and wall-attached interior decoration; such as hotels, restaurants, theaters, shopping malls, offices, etc. Places, broadcasting studios, studios, computer rooms and industrial buildings, etc. [0003] Mineral wool sound-absorbing panels u...
