9 Claims

1. A shear thickening composite material, prepared from a premix and a curing agent; wherein

the premix comprises the following components in parts by weight: 30-80 parts of polyether diol, 20-70 parts of polyether polyol, 1-20 parts of a chain extender, 0.5-3 parts of a cross-linking agent, 5-50 parts of a filler, 0.5-5.0 parts of a coupling agent, 0.05-15 parts of a foaming agent, 0.1-5.0 parts of an emulsifier, and 0.05-5.0 parts of a catalyst; a quantity of hydroxyl groups in the polyether polyol is more than 3, and a hydroxyl value of the polyether polyol is 22-56 mgKOH/g;

the curing agent is diphenylmethane diisocyanate and/or 1,5-naphthalene diisocyanate; and

a molar ratio of hydroxyl groups in the premix to isocyanate groups in the curing agent is 100:105.
