Embodiment 1～5
[0044] A high-strength anti-aging polyvinyl chloride composite material, in parts by weight, including the raw materials described in Table 1 below.
[0045] The raw material composition of table 1 different embodiment
[0046]
[0047]
[0048] Wherein, activated lignin is lignin modified by titanate coupling agent.
[0049] The above-mentioned high-strength anti-light aging polyvinyl chloride composite material is used to prepare PVC-U drainage pipes, and the specific preparation method is as follows:
[0050] Mix the components uniformly at 110°C, cool to 52°C, and then extrude at a mold temperature of 160-175°C and a screw speed of 30 rpm. After cooling and cutting, high-strength anti-aging polyvinyl chloride can be obtained. drain pipe.
Embodiment 6
[0052] A high-strength anti-aging polyvinyl chloride composite material includes the same raw material composition as in Example 3 in parts by weight.
[0053] Wherein the lignin powder is a titanate coupling agent modified lignin, and the specific preparation method is as follows:
[0054] Dilute the titanate coupling agent TC-2 in deionized water at a ratio of 1:8, add 30wt% alkali lignin, and heat the reaction at 60°C for 2h, then place it in a vacuum at 85°C Treat in a drying oven until the solvent is completely evaporated to obtain activated lignin.
