Embodiment 1

[0046] A special material for expressway protective barriers and its preparation method, which uses glass fiber and matrix resin polyvinyl chloride (PVC) to compound, and treats the surface of the glass fiber with a coupling agent and the matrix resin polyvinyl chloride (PVC) through a modifier. PVC) after modification, grafting and cross-linking the olefinic bond of the coupling agent connected to the glass fiber with the matrix resin polyvinyl chloride (PVC), kneading to form a composite material, and then granulating according to the conventional method to obtain A special material for highway protection barriers. Among them, the formula (by weight and mass parts) of the special material for the highway protective barrier includes at least the following materials:

[0047] Base resin polyvinyl chloride (PVC) 100 parts;

[0048] Acrylate series modifier (ACR) 8-10 parts;

[0049] Chlorinated polyethylene modifier (CPE) 8-12 parts;

[0050] 15-25 parts of glass fiber;

Abstract

The invention relates to a special material for polyvinyl chloride (PVC) protection railing of a highway and a preparation method thereof. The preparation method is characterized in that glass fiber is adopted to be compounded with substrate resin PVC, the surface of the glass fiber is processed with coupling agent, the glass fiber is chopped into segments of 2 to 4mm, the subsrate resin PVC is modified through a modifier, a coupling agent olefinic bond which is connected onto the glass fiber is grafted and cross-linked with the substrate resin PVC to be mixed into a composite material, and then the composite material is granulated to produce the special material for the protection railing of the highway.

Description

technical field [0001] The invention relates to a material for highways and a manufacturing method thereof, in particular to a PVC modified special material for expressway protective barriers and a manufacturing method thereof, belonging to the field of new material manufacturing. Background technique [0002] At present, the protective barriers used on expressways are mostly made of steel. However, steel guardrails are heavy, inconvenient to install, repair and maintain, have poor corrosion resistance, and are easily eroded by automobile exhaust. Poor identification ability. Impact resistance also needs to be improved. Due to the advancement of plastic technology and the improvement of plastic performance, it is an inevitable development trend for plastics and their composite materials to enter highway barriers. The use of plastic barriers for highways has many advantages and can overcome many shortcomings of steel guardrails. However, without improvement or compounding ...
