Embodiment
[0039] The invention provides a special material for making polystyrene pipes, which includes polystyrene recycled broken material, toughening agent, HDPE (high density polyethylene) broken material, filler, EBS (ethylene bis stearamide), Antioxidant, coupling agent, stearic acid. The ratio of parts of various components is as follows:
[0048] Among the above components, the toughening agent can be SBS or SEBS; the filler can be talcum powder, or it can be obtained by mixing wollastonite and talc powder in a ratio of 1:2.
[0049] The coupling agent is preferably a titanate coupling agent (the addition ratio of titanate is 2%); and the antioxidant is preferably antioxidant 1010.
[0050] The above components can be pr...
example 1
[0059] The various components of special materials, the number of parts are: polystyrene recycled crushed material: 90 parts, SBS: 2 parts, HDPE crushed material: 3 parts, talcum powder: 4 parts, EBS: 0.2 parts, antioxidant: 0.2 parts, coupling agent: 0.4 parts, stearic acid: 0.2 parts.
example 2
[0061] The various components of special materials, the number of parts are: polystyrene recycled crushing material: 80 parts, SEBS: 4 parts, HDPE crushing material: 5 parts, wollastonite: 2 parts, talcum powder: 4 parts, EBS: 0.5 parts, antioxidant: 0.5 parts, coupling agent: 3.5 parts, stearic acid: 0.5 parts.
[0062] Table 1 shows the performance comparison of pipes made of special materials obtained from the components of Example 1 and Example 2 with PP pipes and ordinary polystyrene pipes. The comparison parameters also include ring stiffness, deformation, and TIP.
[0063]
[0064] Table 1
[0065] It can be seen from Table 1 that the pipes prepared from the special materials obtained in Examples 1 and 2 of the present invention have obvious advantages in various technical parameters compared with PP pipes and ordinary polystyrene pipes. , the TIP value of rigidity (ring stiffness), flexibility (deformation) and drop weight impact of the polystyrene pipe made by the...

Abstract
The invention discloses a special material for polystyrene pipes and a preparation method thereof. The special material is composed of polystyrene recycled broken material, toughening agent, HDPE broken material, filler, EBS, antioxidant, coupling agent and stearic acid The preparation method of special materials includes: (1) cleaning, drying and homogenizing polystyrene recycled materials; (2) crushing polystyrene recycled materials and HDPE materials respectively, and mixing them with toughening agents Stir; (3) add EBS, antioxidant and stearic acid in turn and mix, and stir again; (4) add the filler after surface activation, and continue to stir; (5) extrude the mixture in a molten state, Obtain special material for polystyrene pipe. When the invention is used to make polystyrene pipes, the comprehensive mechanical properties (rigidity, flexibility, toughness) of polystyrene pipes are greatly improved, and the cost of pipe production is effectively reduced, meeting the requirements of "health, safety and environmental protection" of green plastic pipes requirements.
Description
technical field [0001] The invention relates to a special material for pipes, in particular to a special material for polystyrene pipes and a preparation method thereof. Background technique [0002] Stimulated by increasing demand in municipal engineering, construction, agriculture, industry and other industries, the plastic pipe industry has developed rapidly. At present, the most used areas of plastic pipes in my country are mainly urban construction water supply and drainage systems. In recent years, polyethylene pipes (PE), polypropylene pipes (PP), polybutylene pipes (PB), polystyrene pipes (PS) and aluminum-plastic composite pipe (PAP) and other water supply and drainage pipe sales increased rapidly. In 2003, the domestic consumption of plastic pipes in this field reached 300,000 tons, and a complete industrial chain of special pipe materials, pipe processing, and municipal engineering applications has been formed. Many plastic pipe manufacturers have also begun to le...
