Problems solved by technology

[0003] In the prior art, the main problems of flame retardants suitable for polyurethane adhesives are: 1. There are many types of flame retardants, each with its own characteristics and effects, and it is difficult to choose a suitable model; 2. Two-component Polyurethane adhesives generally use calcium carbonate as a filler, which has a certain impact on the flame retardant effect of nitrogen-phosphorus flame retardants; 3. Liquid flame retardants have a certain plasticizing effect, and the added double-group 4. The flame retardant effect of halogen-based flame retardants is better, but it will release harmful substances during combustion and heating, threatening human health, the environment and the next generation.

Embodiment 1

[0018] Example 1, a high-efficiency flame-retardant two-component polyurethane adhesive comprises the following components:

[0019] 40 kg of polyester polyol;

[0020] Calcium carbonate 28 kg;

[0021] Flame retardant 20 kg;

[0022] Molecular sieve 2 kg.

[0023] The above-mentioned materials are all commercially available, and the polyester polyol is purchased from Shanxi Kaixirui Technology Co., Ltd. The calcium carbonate was purchased by Xinxiang Yuanfeng Calcium Industry Co., Ltd. The flame retardant is a nitrogen-phosphorus flame retardant purchased from Guangzhou Guanyou Chemical Technology Co., Ltd. The molecular sieves were purchased from Nanjing Yongcheng Molecular Sieve Co., Ltd. Of course, the raw materials involved in this formula come from a wide range of sources. Polyester polyols, calcium carbonate, molecular sieves, and nitrogen-phosphorus flame retardants can all be replaced by other similar raw materials.

[0024] The blending process is as follows: a...

Abstract

The invention discloses an efficient flame retardant two-component polyurethane adhesive comprising the following components and the weight parts of the corresponding components: 40 parts by weight of polyester polyol; 28 parts by weight of calcium carbonate; 20 parts by weight of a flame retardant; and 2 parts by weight of molecular sieve. Even if the flame retardant is added in the two-component polyurethane adhesive, no obvious influence on the properties of an original two-component polyurethane adhesive exists, and the original cohesive strength, bonding strength, color appearance, viscosity, application time, foaming rate and main solid ratio can be substantially kept.

Description

technical field [0001] The invention relates to the technical field of the adhesive industry, in particular to a high-efficiency flame-retardant two-component polyurethane adhesive. Background technique [0002] In the adhesive industry, there are various requirements for adhesive properties, and flame retardant is one of them. Currently used flame retardants are halogen-based, nitrogen-based, phosphorus-based, and inorganic-based. [0003] In the prior art, the main problems of flame retardants suitable for polyurethane adhesives are: 1. There are many types of flame retardants, each with its own characteristics and effects, and it is difficult to choose a suitable model; 2. Two-component Polyurethane adhesives generally use calcium carbonate as a filler, which has a certain impact on the flame retardant effect of nitrogen-phosphorus flame retardants; 3. Liquid flame retardants have a certain plasticizing effect, and the added double-group 4. The flame retardant effect of...
