Embodiment 1
[0039] 305g of dibutyl phthalate, 10g of bisphenol A type epoxy resin, 151g of high rubber powder, 103g of benzoyl peroxide and 11.5g of castor oil were mixed uniformly to obtain an oxidizing agent.
[0040] Mix 206.5g methyl methacrylate, 103.1g impact modifier, 101.5g chlorosulfonated polyethylene, 10g triethylenediamine, 5.1g paraffin, 10.8g acrylic acid, 3.2g stabilizer and 12g organomodified bentonite Evenly, the reducing agent is obtained.
[0041] In parts by volume, 1 part of oxidizing agent and 8 parts of reducing agent are uniformly mixed to obtain acrylate glue.
[0042]In this example, the impact modifier is a mixture of ABS, ACR and MBS with a mass ratio of 1:1:1, the paraffin wax has a melting point of 47°C, and the stabilizer is hydroquinone, naphthoquinone, or benzoquinone. Mixture, its mass ratio is 1:2:3.
