Embodiment 1
[0027] A profile used for guardrails, the mass parts of which are composed of raw materials include: 80 parts of polyvinyl chloride resin, 1 part of rare earth stabilizer, 1 part of zinc stearate, 1 part of barium stearate, and 1.5 parts of polyacrylate resin 3 parts, impact modifier 3 parts, titanium dioxide 3 parts, metal oxide 10 parts, metal powder 10 parts, stearic acid 0.1 part, solid paraffin 0.1 part, ASA / PMMA resin 1 part, microemulsion 1 part.
[0028] Specifically, the density of the polyvinyl chloride resin is 1.35~1.45g / cm 3 , the apparent density is 0.4~0.5 g / cm 3 .
[0029] Specifically, the polyvinyl chloride resin is a compact polyvinyl chloride resin, the particle size of which is less than 0.1 mm, and is in the shape of a table tennis ball.
[0030] Specifically, the rare earth stabilizer is any one or multiple combinations of rare earth oxides, rare earth chlorides, single rare earth elements, and mixtures of rare earth elements. It has excellent thermal ...
