The invention discloses an anti-collision protection lining and an
ice hockey helmet, and relates to the field of safety protection buffer functional materials, the anti-collision protection lining comprises an outer layer high
microsphere density area, a middle layer
fiber reinforcement area, an inner layer
low density opening area and an inner layer composite antibacterial foaming
polypropylene foam layer; the preparation of the anti-collision protection lining comprises the following steps: adding
polyvinyl alcohol and
polyethylene glycol into hot water for dissolving, adding
silicon dioxide
aerogel powder for stirring, and carrying out
boric acid crosslinking, alkali treatment,
polyurethane prepolymer coating and high-pressure hot
air dispersion drying; performing
plasma activation and
maleic anhydride grafting; the preparation method comprises the following steps: mixing a component A containing nano
colloid microspheres and grafted fibers with a polyisocyanate component B according to a ratio of 1: 1, and carrying out foaming molding to form a
microsphere gradient enrichment layer; antibacterial foamed
polypropylene foam is attached to the perforated layer in a hot-pressing mode and
cut; through molecular flexible modification,
microsphere elastic
coating and interface strengthening and gradient
energy distribution, the use reliability and
impact resistance of the
ice hockey helmet are improved.
