Embodiment 1
[0024] (embodiment 1, polyvinyl chloride toughening modifier)
[0025] This embodiment is a polyvinyl chloride toughening modifier, comprising:
[0026] Methyl methacrylate-butadiene-styrene copolymer is also called MBS: 1.1 parts; the specific choice is the MBS produced by Japan Zhongyuan Company with the brand name B564;
[0027] Acrylic ester impact modifier is also called ACR impact modifier: 10.5 parts; specifically select the ACR impact modifier of KM355P produced by Singapore Kureu Company; the acrylate impact modifier It is a core-shell copolymer formed by the copolymer of alkyl acrylate and methyl methacrylate or acrylate and methyl methacrylate as the shell, and the elastomer formed by crosslinking butyl acrylate as the core. The parts of the above-mentioned components are all parts by weight.
[0028] The composition and proportioning of this embodiment are shown in Table 1.
