Abstract
The invention discloses a flame-retardant polyether polyol which is characterized by comprising raw materials of 3, 4-dibromo-3-chloro-1, 2-butanediol, a catalyst and alkylene oxide. The invention also discloses a preparation method of the single-component polyurethane foam joint mixture taking the single-component polyurethane foam joint mixture as a raw material. The flame-retardant polyether polyol contains bromine and chlorine at the same time, so that the flame-retardant property of the OCF foam prepared by the flame-retardant polyether polyol can be effectively improved. The limited flame-retardant polyether polyol meets the requirements of OCF on low-functionality polyether, low-molecular weight and low-viscosity, and the problems of large OCF residual glue amount, low foaming multiplying power and the like are not caused; the initiator has low toxicity, can be less harmful to workers in industrial production, and has little pollution to the environment. The preparation method of the single-component polyurethane foam joint mixture is simple and convenient for daily use.
Description
Technical Field
The invention relates to the technical field of organic material synthesis, in particular to flame-retardant polyether polyol and a single-component polyurethane foam joint mixture using the same as a raw material.
Background
One-component polyurethane foam caulking (OCF) is a special moisture-curing rigid polyurethane foam system. Polyurethane prepolymer, catalyst, foaming agent and the like are filled in a pressure-resistant aerosol can, and when the material is ejected from the aerosol can, the foam-shaped polyurethane material rapidly expands and is solidified with air or moisture in a contacted matrix to form foam. The solidified foam has excellent performances of joint filling, bonding, sealing, heat insulation, sound insulation and the like, and is widely used for filling and sealing side seams of doors and windows of buildings, expansion joints of members and holes. With the rapid development of national residential construction and the continuous improvement of household conditions, the requirements of people on the quality of the building engineering are increasingly high. As a common building material, the single-component polyurethane foam joint mixture has become a key point for research at home and abroad to improve the flame retardant property of the single-component polyurethane foam joint mixture. The flame retardant effect of the one-component polyurethane foam caulking agent on the market at present is poor, and the majority is in the grade of B3 or B2 (DIN 4102B 1). There are two methods for improving the flame retardant properties of single component polyurethane foam caulking agents: 1. flame retardants are added such as tris (2-chloroethyl) phosphate (TCEP), tris (2-chloropropyl) phosphate (TCPP), dimethyl methylphosphonate (DMMP), chlorinated paraffins, and the like. The flame retardant can effectively improve the flame retardant property of the OCF, but at the same time, the problems of increased plasticity, poor adhesive force, splashing during foam ejection and the like of the OCF foam can be caused. 2. Flame retardant polyether polyols are used. Flame retardant elements such as chlorine, bromine, nitrogen, phosphorus and the like are introduced into the polyether polyol. The method has little influence on the mechanical property of the foam and long time for maintaining the flame retardant effect, and has become an important method for improving the flame retardant property of the OCF.
For example, chinese patent document CN109306056a mentions a reactive flame retardant polyether polyol for OCF joint compound and a preparation method thereof, and the flame retardant polyether polyol obtained by the method has good flame retardant property and good dimensional stability, but the product prepared by the method has high viscosity (4000-5000 mpa·s), and the application of the reactive flame retardant polyether polyol in OCF can cause problems of large residual glue amount, low tensile bonding strength, brittle foam, low foaming multiplying power and the like.
Disclosure of Invention
Therefore, the technical problem to be solved by the invention is to overcome the defects of large residual glue amount, poor foam adhesion, brittle foam and low foaming multiplying power caused by large viscosity of the flame-retardant polyether polyol in the existing single-component polyurethane foam joint mixture, and further provide the flame-retardant polyether polyol and the single-component polyurethane foam joint mixture using the flame-retardant polyether polyol as raw materials.
In order to solve the technical problems, the invention adopts the following technical scheme:
the invention provides a flame-retardant polyether polyol, which comprises raw materials of 3, 4-dibromo-3-chloro-1, 2-butanediol, a catalyst and alkylene oxide.
Further, the functionality of the flame-retardant polyether polyol is 2, the bromine content is 25-35 wt%, the chlorine content is 6-8 wt%, the hydroxyl value is 200-250 mgKOH/g, and the viscosity at normal temperature is 2700-3200 mPa.s.
Preferably, the molar ratio of 3, 4-dibromo-3-chloro-1, 2-butanediol to alkylene oxide is 1:3-7.
