Description

A kind of processing method for improving Algae-resistant fishing net lasting effect
Technical field
The invention belongs to fishing net processing technique field, and in particular to a kind of processing method of raising Algae-resistant fishing net lasting effect.
Background technology
China's culture fishery is quickly grown, it is necessary to which using substantial amounts of fishing net, fishing net is typically by polyethylene, polychlorostyrene second Alkene, polypropylene or nylon are that the yarn woven that raw material is made is formed, different according to cultivation object, sealike colour and mesh size Have nothing in common with each other；In use, fishing net needs to be immersed in water for a long time, is highly prone to algae, liver moss, fungi, barnacle, dragon The erosion of the aufwuches such as Jie, mussel, oyster and amphipoda, so as to shorten its service life, in order to solve this problem, There are a large amount of researchs on Algae-resistant fishing net, but popularization and application are seldom, to find out its cause, mainly there is following several respects：Anti- algae preparation is molten Yu Shui, can be polluted to waters；Anti- algae poor performance, lasting effect is poor；Film forming is poor, easily makes that product is tacky, quality is not good；Also There is the problem of price height is unfavorable for popularization；Therefore, in above mentioned problem should be considered in when considering solution.
The content of the invention
The purpose of the present invention is that there is provided a kind of processing method for improving Algae-resistant fishing net lasting effect the problem of being directed to existing.
The present invention is achieved by the following technical solutions：A kind of processing method for improving Algae-resistant fishing net lasting effect, including Following steps：
（1）Pressed using ultra-high molecular weight polyethylene, nylon, polypropylene, modified red stilbite powder, erucyl amide, Naproxenic acid Weight compares 100：28-35:12-17:6-10:0.8-1.4:0.2-0.7, blending is merged into nettle；
（2）It is 1.8 × 10 that gained nettle is placed in into vacuum-2Pa-3.2×10-2In Pa reactor, being passed through mass concentration is 2% sulfuric acid vapor, after handling 2.5-3 hours, recovers normal pressure, is baked to 1.5-2 hours, standby；
（3）Remove algae paint in above-mentioned standby antibacterial of the nettle surface spraying containing ethylene acrylic, after the completion of with irradiation dose be 10- 20kGy gamma-radiation irradiation, irradiation is produced after 2-6 hours；
（4）By the nettle after processing have knot netting machine on fishing net is made.
As further improvement of these options, the polyacrylic melt index is 3.0-4.0g/10min.
As further improvement of these options, the ultra-high molecular weight polyethylene is 102- using preceding in temperature Dried 6-8 hours under conditions of 108 DEG C.
As further improvement of these options, the preparation method of the modified red stilbite powder is：By epidesmine Powder is that constant temperature drying is to constant weight under conditions of 300 DEG C in temperature, then with the magnesia equivalent to its weight 12-18%, 1-3% Erucyl amide is mixed, and then mixes its absolute ethyl alcohol dilution with mass concentration for 0.8-1.5% silane coupler Even, then ultrasonic disperse 10-15 minutes is stirring reaction 30 minutes under conditions of 120-135 DEG C in temperature, it is heavy to be collected by filtration Form sediment, pulverized after drying, cross 120 mesh sieves and produce.
As further improvement of these options, the step（2）Middle drying temperature is 50-60 DEG C.
As further improvement of these options, the antibacterial containing ethylene acrylic includes following weight except algae paint The raw material of part：Between 100 parts of acrylic resin, 2.2-4.5 parts of glass microballoon, 20-25 parts of acetone, 4-7 parts of ethylene acrylic, tetrachloro 8-12 parts of benzene dicarbonitrile, 4.5-8 parts of N- (chlorophenyl) maleimides, 1.2-2.5 parts of dithiocyano-methane, phosphine oxide nitrile 0.8-1.2 parts, copper -1.8-4.5 parts of 2-mercaptobenzothiazole；Wherein ethylene acrylic can improve coating and be handled with sulfuric acid vapor The compatibility on nettle surface afterwards, it is in network structure to make its adhesive surface.
The present invention has advantages below compared with prior art：By adding modified red stilbite in nettle in the present invention Powder, makes itself have certain antibacterial ability, modified red stilbite powder can be combined preferably with matrix, and transmission meets with stresses, The hole of effective filled composite materials, serves as the effect of the strong point in the composite, improves the compression performance of composite, resistance The only insertion and cutting of abrasive particle, so as to improve the wearability and intensity of composite；Then by using sulfuric acid under vacuum Steam treatment, makes nettle surface form one layer of complicated compact texture, then removed in antibacterial of its surface spraying containing ethylene acrylic Algae paint, after the completion of irradiated with low irradiation dose gamma-radiation, the adhesion strength on increase coating and nettle surface solves monofilament The problem of surface gloss paint is difficult attachment；Also improve the impact resistance and wearability of fishing net to a certain extent simultaneously, Coating not facile hydrolysis, the anti-algae ability of antibacterial is strong, and lasting effect is up to more than 2 years under normal usage.
