Description

A kind of acid and alkali-resistance fishing net

Technical field

The present invention relates generally to a kind of fishing net, relates in particular to a kind of acid and alkali-resistance fishing net.

Background technology

Modern fishing net mainly adopts polyethylene, the raw materials such as nylon are processed, wherein polythene fishing net, to adopt polythene material through fusion plastification, spinning, plying is twisted thread and is made into, use Yu Haiyang trawlnet, purse seine, wind resistance sea net cage etc., there is longer life cycle, higher catching rate, but the mechanical property of polyethylene itself is general, TENSILE STRENGTH is lower, creep resistance is bad, just cause the intensity of conventional polyethylene fishing net, anti-wear performance, at the bottom of toughness is unwell to Complex Sea and wind and waves environment fishing operation, reduced the service life of fishing gear, not only waste resource, also directly affect catch.

Summary of the invention

The object of the invention is just to provide a kind of acid and alkali-resistance fishing net.

The present invention is achieved by the following technical solutions:

A kind of acid and alkali-resistance fishing net, it is comprised of the raw material of following weight parts:

Ultra-high molecular weight polyethylene 92-100, linear low density polyethylene 5-7, Mono-n-butyltin 0.2-0.4, pentaerythrite 2-3, urea groups propyl-triethoxysilicane 1-2, modification plasticizer 3-4;

Described modification plasticizer is comprised of the raw material of following weight parts: MTES 1-1.2, dioctyl ester 2-2.3, ATBC 1.2-1.4, peanut oil 2-2.3, turpentine oil 1-1.2, eucalyptus oil 0.3-0.4, poly-different diene 1.2-1.4, morpholine 0.2-0.3, antioxidant MB 1-1.2, methyl ethyl ketone peroxide 0.2-0.3, styrene 1.2-1.4, nano titanium oxide 0.2-0.3;

Above-mentioned methyl ethyl ketone peroxide is added drop-wise in other each mixtures of materials, and stirring reaction 60-90 minute, is warming up to 120-130 ℃, and stirring reaction 2-3 hour obtains described modification plasticizer.

A preparation method for acid and alkali-resistance fishing net, comprises the following steps:

The urea groups propyl-triethoxysilicane of getting above-mentioned weight 10-15% mixes with linear low density polyethylene, stirring reaction 10-15 minute at 60-70 ℃, add pentaerythrite, continue insulated and stirred 5-8 minute, be cooled to normal temperature, add the each raw material of residue, by extruder, melt extrude, drawing-off, sizing, spinning, obtain described acid and alkali-resistance fishing net.

Advantage of the present invention is:

The fishing net that the present invention produces has good toughness, tensile strength and weather resisteant, and acid-alkali-corrosive-resisting is strong, to the strong adaptability of water body, can increase the service life.
