Abstract

The invention relates to a special adhesive resin for a wire-frame-reinforced polyethylene tube and a production method thereof. The special adhesive resin for a wire-frame-reinforced polyethylene tube is mainly used for bonding the outer layer, wire and inner layer of a wire-mesh-frame-reinforced polyethylene tube. The special adhesive resin for a wire-frame-reinforced polyethylene tube is prepared from the following raw materials in percentage by weight: 30-90% of HDPE (high-density polyethylene), 8-40% of LLDPE (linear low-density polyethylene), 0.1-10% of maleic anhydride, 0.01-1% of peroxide crosslinking agent and 0.01-1% of acetone. The production method comprises the following steps: carrying out pre-reaction on the maleic anhydride, peroxide and acetone, mixing with the HDPE and LLDPE, and carrying out thermal granulation. By using the product provided by the invention, the peel strength among the outer layer, wire and inner layer of the wire-mesh-frame-reinforced polyethylene tube is up to more than 500N/25mm.

Description

A kind of steel-wire carcass strengthens polyvinyl piping materials special bonding resin and method of manufacture thereof
Technical field
The present invention relates to plastics tubing, be specially a kind of steel-wire carcass and strengthen polyvinyl piping materials special bonding resin, mainly use steel-wire carcass and strengthen bonding between polyvinyl piping materials skin, steel wire, the internal layer.
Background technology
At present; Domestic do not have specialty to be applicable to that steel-wire carcass strengthens the special-purpose adhering resin of polyvinyl piping materials; It is the grafts of singly depositing that existing steel-wire carcass strengthens the employed adhering resin of polyvinyl piping materials, and its shortcoming is that cost is high, stripping strength is low, the use difficulty is big, is prone to bubble etc.
Summary of the invention
In order to overcome the defective of prior art, reduce the production use cost, improve stripping strength, be prone to use, stop bubble appearance etc., the present invention to provide a kind of steel-wire carcass to strengthen polyvinyl piping materials special bonding resin and method of manufacture thereof.
The technical scheme that the present invention taked is: a kind of steel-wire carcass strengthens polyvinyl piping materials special bonding resin; Its material composition weight ratio is: HDPE 30-90%, LLDPE 8-40%, maleic anhydride 0.1-10%; Peroxide cross-linking agent 0.01-1%, acetone 0.01-1%; Wherein, HDPE is a high density polyethylene(HDPE), tensile strength >=23Mpa, elongation at break >=600%, Vicat softening point >=120 ℃, more than the melt flow rate(MFR) 1g/10min; LLDPE is a linear low density polyethylene, fracture tensile strength >=10Mpa, elongation at break >=1000%, Vicat softening point >=95 ℃, more than the melt flow rate(MFR) 20g/10min.
More specifically the material composition weight ratio is: HDPE 70%, and LLDPE 20%, maleic anhydride 2%, peroxide cross-linking agent 0.1%, acetone 0.1%.
Said peroxide cross-linking agent is a Di Cumyl Peroxide 99.
Its production technique comprises the steps:
Earlier maleic anhydride and superoxide are mixed;
Add acetone, restir evenly becomes small powder, deposits more than 10 hours at 10 ℃ of-50 ℃ of room temperature inner openings of temperature, and this process can make maleic anhydride, superoxide and acetone carry out pre-reaction;
HDPE, LLDPE are joined 1.5-10 minute one-tenth of stirring compound in the spice machine together with above-mentioned small powder;
Above-mentioned compound is sent into dual-screw-stem machine carry out graft reaction and granulation, 200 ℃-240 ℃ of melt temperatures of control, the residence time 30-240 second of material in machine barrel.
Beneficial effect of the present invention: a kind of steel-wire carcass strengthens polyvinyl piping materials special bonding resin; In macromolecular chain, add polar group (maleic anhydride) with the grafting form; Guaranteeing to increase cementability under higher draw tensile strength and the elongation at break situation; Suitably add LLDPE, can significantly improve workability.Process using is reacted again earlier, and the grafted method reduces difficulty of processing.Use steel-wire carcass of the present invention to strengthen the steel-wire carcass enhancing polyvinyl piping materials that polyvinyl piping materials special bonding production of resins goes out; Stripping strength between its skin, steel wire, the internal layer reaches 500N/25mm above (seeing accompanying drawing 1), satisfies its needed stripping strength requirement fully.And reduce the production use cost, stop bubble appearance etc.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further specified.
The steel-wire carcass enhancing polyvinyl piping materials that Fig. 1 produces for using the present invention, the power of the stripping strength between its skin, steel wire, the internal layer-deformation curve figure.
Embodiment
Embodiment:: a kind of steel-wire carcass strengthens polyvinyl piping materials special bonding resin, material composition weight ratio: HDPE70%, LLDPE20%, maleic anhydride 2%, Di Cumyl Peroxide 99 linking agent 0.1%, acetone 0.1%.
Its production technique comprises the steps:
Earlier maleic anhydride and superoxide are mixed;
Add acetone, restir evenly becomes small powder, deposits more than 10 hours at 10 ℃ of-50 ℃ of room temperature inner openings of temperature, and this process can make maleic anhydride, superoxide and acetone carry out pre-reaction;
HDPE, LLDPE joined in the spice machine together with above-mentioned small powder stirred 1.5-10 minute;
Above-mentioned compound is sent into dual-screw-stem machine carry out graft reaction and granulation, 200 ℃-240 ℃ of melt temperatures of control, the residence time 30-240 second of material in machine barrel.
