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.

[0029] Table 1

[0030]

Embodiment 2 to Embodiment 3

[0032] Embodiment 2 to Embodiment 3 are basically the same as Embodiment 1, the difference is that: the ratio of raw materials used is different, and the specific ratio is shown in Table 1.

Embodiment 4 to Embodiment 6

[0034] Embodiment 4 to Embodiment 6 are basically the same as Embodiment 1, except that the ACR impact modifier is ACR401 produced by Taixing Linjiang Chemical Factory. See Table 1 for the specific proportioning of each embodiment in Embodiment 4 to Embodiment 6.

Abstract

The invention discloses a polyvinyl chloride toughening modifier, which comprises 1.0 to 2.0 portions of methylmethacrylate butadine stryrene copolymer which is also called MBS, and 6 to 15 portions of acrylates impact modifier which is also called ACR impact modifier; and the portion of the compositions is weight portion. The polyvinyl chloride toughening modifier has good toughening and modification effects on polyvinyl chloride.

Description

technical field [0001] The invention belongs to the technical field of plastic pipes, in particular to a polyvinyl chloride toughening modifier. Background technique [0002] Polyvinyl chloride is one of the most widely used thermoplastics. At present, the annual consumption of polyvinyl chloride in the world is about 30 million tons, of which about one-third is used in pipes and fittings. Although facing competition from other plastic pipes, PVC pipe systems are still the most used plastic pipes so far. [0003] For a long time, PVC water supply pipes have once become the first choice in our country. In the 21st century, traditional PVC pipes face many competitors, especially PE pipes with excellent toughness and water hammer impact resistance. It seems that there is no other countermeasure except for price wars and cost control. [0004] There are usually two forms of damage to plastic pipes, one is ductile failure and the other is brittle failure. Compared with PE pipe...
