Abstract

The invention discloses a vacuum bag membrane material as well as a preparation method and application thereof. The vacuum bag membrane material consists of the following components in percentage by weight: 30-72% of polycaprolactam, 25-69% of copolymer nylon and 1-3% of additives, wherein the additives consist of an anti-blocking agent and an antioxidant. The vacuum bag membrane material disclosed by the invention can be used for preparing vacuum bag membranes. An obtained product has the tensile strength of more than or equal to 70 MPa, the elongation at break of more than or equal to 350%, and the highest operating temperature of 150 DEG C; meanwhile, the vacuum bag membrane material reduces the cost, and is simple in method and easily-available in material.

Description

A kind of vacuum bag mould material, preparation method and its usage
Technical field
The present invention relates to Material Field, relate in particular to a kind of vacuum bag mould material, preparation method and its usage.
Background technology
Original wind power generation blade uses low temperature ethylene base resin, and forming and hardening temperature is 120 DEG C, and fiber is mainly glass fibre.Along with the requirement to blade work-ing life and environment promotes, carbon fiber progressively promotes in blade applications ratio, and foreign trader's Vestas, Gamesa Wind etc. have adopted carbon glass fiber shuffling technique, promotes product property.The variation of technique directly causes forming and hardening temperature to improve, and the vacuum bag film of existing polyethylene/polycaprolactam cannot satisfied temperature demand, faces the risk being eliminated.
Summary of the invention
The object of the present invention is to provide the better vacuum band of a kind of performance mould material.
For achieving the above object, a kind of vacuum bag mould material, is characterized in that, is made up of 30-72 % by weight polycaprolactam, 25-69 % by weight copolymer nylon and 1-3 % by weight additive.
Described additive is opening agent and oxidation inhibitor composition.
The part by weight of described opening agent and oxidation inhibitor is 1:1-1:3.
Described opening agent is erucicamide or silicon-dioxide or Zinic stearas.
Described oxidation inhibitor is Copper Complex or Hinered phenols.
Described Copper Complex is cupric ion oxidation inhibitor.
Described Hinered phenols is oxidation inhibitor 1098.
The present invention also protects the preparation method of described vacuum bag mould material, by the polycaprolactam of aequum, copolymer nylon and additive physical mixed.
Described vacuum bag mould material is for the preparation of the purposes of vacuum bag film
Costco Wholesale: the film of the present invention with equal-specification exceeds 20-30% than existing composite membrane, but under equal performance, cost can reduce 5-10% slightly.
The inventive method is simple simultaneously, and material is easy to get.
Because the tensile strength of polycaprolactam is poly 200-300%, elongation is poly 50-70%.The tensile strength of copolymer nylon is poly 200-300%, and elongation is poly 70-90%.By the allotment of ratio of the present invention, under the approaching condition of elongation, the 120-150% that tensile strength is composite membrane, can effectively reduce thickness 20-30%, cost savings 5-10%.
Innovative point:
By multi-layer co-extruded technology, by the material comprehensive advantage of different performance, produce rational composite membrane.
The physical property of product: tensile strength >=70MPa, is specially 70～90MPa;
Fracture elongation >=350%, is specially 350～400%;
Maximum operation (service) temperature is 150 DEG C-160
Market polyethylene/polycaprolactam performance is followed successively by 40MPa, 450%, 120 DEG C.
Technical process:
Weigh → mix and blend of proportioning → extrude shearing → Blown Film → cooling rolling → packaging shipment
Compliance test result:
All adopt GB or American Standard universal test way, as tensile strength and elongation: ASTM-D882.
Equipment aspect:
Common nylon-type forcing machine, without particular requirement.The place of production: Shantou, Guangdong.
