preparation example Construction

[0048] The present invention also provides a method for preparing a lightweight flame-retardant sponge, the steps of which include:

[0049] Temperature control and stirring of polyether polyol PPG and toluene diisocyanate TDI of corresponding mass parts;

[0050] Stir and mix the temperature-controlled and stirred polyether polyol PPG and toluene diisocyanate TDI and the remaining components of the corresponding mass parts to form a sponge foam;

[0051] The obtained sponge body is subjected to aging treatment.

[0052] Further, the steps of the method also include: cutting the cured lightweight flame-retardant sponge according to customer requirements.

[0053] Further, the control temperature of the temperature control is 23-25°C; this temperature range is limited to the optimum foaming temperature of the above components, and the foaming is relatively stable if the temperature is limited within this range.

[0054] Further, the stirring speed during the temperature contr...

Abstract

The invention discloses a lightweight flame-retardant sponge and a preparation method and application thereof. The lightweight flame-retardant sponge is formed by foaming, molding and curing the following components in parts by mass: 100 parts of polyether polyol PPG; 110 to 120 parts of toluene diisocyanate TDI; 0.4 to 0.8 part of a halogen-free reactive flame retardant, 0.6 to 1 part of a catalyst; 6-8 parts of silicone oil; 90-110 parts of methylene chloride; 12-15 parts of water; 0.4 to 0.8 part of an antioxidant; 1-1.5 parts of a plasticizer; 0.4 to 0.8 part of a heat stabilizer and 1-1.5parts of glycerol. The density of the lightweight flame-retardant sponge can be reduced, the quality of materials with the same volume can be reduced, the toughness is improved, and the manufacturingcost is reduced.

Description

technical field [0001] The invention relates to a lightweight flame-retardant sponge, a preparation method and application thereof. Background technique [0002] At present, the foam sponges on the market have the lowest density sponges at 8-10kg / m 3 , the demand for lightweight filling materials in the automotive or motor vehicle industry cannot be met. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art and provide a lightweight flame-retardant sponge, which can reduce its density, reduce the quality of materials with the same volume, improve its toughness, reduce manufacturing costs, and improve the success of foaming. Rate. [0004] In order to solve the above technical problems, the present invention provides a lightweight flame-retardant sponge, which is formed by foam molding and aging treatment of the following components in corresponding parts by mass, including: [0005] Pol...
