specific Embodiment approach 1

[0015] Specific implementation mode 1: This implementation mode is a method for preparing a polyethylene modified material used in a honeycomb restraint system, which is specifically completed according to the following steps:

[0016] 1. Preparation of component A: 20-70 parts of HDPE resin, 6-10 parts of low-temperature toughening modifier, 0.2-0.4 parts of antioxidant, 0.9-1.3 parts of cross-linking modifier and 1-3 parts of lubricant Mix evenly to obtain the mixture A, transfer the mixture A to a mixer for mixing, the mixing temperature is 140-180°C, and the mixing time is 5min-20min, and the A component is obtained;

[0017] 2. Preparation of component B: weigh 8 to 15 parts of LLDPE resin, 0.1 to 0.15 parts of initiator, 0.1 to 0.15 parts of crosslinking agent and 0.2 to 0.4 parts of crosslinking catalyst, weigh them and put them into the mixer at a speed of 30r / min~40r / min and mixed for 5min~10min to get mixture B, put mixture B into SHJ series twin-screw extruder. Th...

specific Embodiment approach 2

[0025] Specific embodiment 2: The difference between this embodiment and specific embodiment 1 is that in step 1, 60-70 parts of HDPE resin, 9-10 parts of low-temperature toughening modifier, 0.2-0.3 parts of antioxidant, 0.9- 1.3 parts of cross-linking modifier and 1-3 parts of lubricant A are uniformly mixed to obtain mixture A. Others are the same as the first embodiment.

specific Embodiment approach 3

[0026] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: the HDPE resin described in step one has a fluid flow rate of 7.98g / 10min -1 of high-density polyethylene. Others are the same as those in Embodiment 1 or 2.

Abstract

The invention provides a preparation method of a polyethylene modified material used for a honeycomb restraint system, relating to preparation methods of polyethylene modified materials and aiming to solve the problems of elongation reduction and brittleness increase caused after thermal oxidation and photoaging of existing polyethylene plastics. The preparation method comprises the following steps: I. preparing a component A by using HDPE (high density polyethylene) resin, a low-temperature toughening modifier, an antioxidant, a crosslinking modifier and a lubricating agent as raw materials; II. preparing a component B by using LLDPE (linear low density polyethylene) resin, an initiator, a crosslinking agent and a crosslinking catalyst as raw materials; III. using the component A, the component B, a lubricating agent B and a surfactant as raw materials and carrying out mixing and extrusion, thus obtaining the polyethylene modified material used for the honeycomb restraint system. The preparation method is mainly used for preparing the polyethylene modified material used for the honeycomb restraint system.

Description

technical field [0001] The invention relates to a preparation method of a polyethylene modified material. Background technique [0002] With the continuous development of material technology, product performance, and functional innovation engineering methods, a technology that uses polyethylene modified materials to produce honeycomb restraint system products has been applied in the field of ecological slope protection. This technology retains its original advantages. Now, the transformation of long-term, civilian use and engineering has been realized, especially the development of subversive polymer composite alloy. On the basis of satisfying long-term use, the use of the material of the present invention to produce honeycomb restraint system products not only prevents soil materials from It is the most effective solution for soil stabilization, load-bearing slope protection, river canal protection, and vegetation retaining walls. [0003] The carrier materials currently u...
