Embodiment 1

[0045] Modified calcium carbonate whiskers are prepared by the following steps:

[0046] Step B1: Mix the silane coupling agent KH550 and ethanol according to the dosage ratio of 10mL: 17.5mL to prepare a modified liquid for later use; take calcium carbonate whiskers and deionized water according to the dosage ratio of 10g: 24.5mL to obtain a dispersion liquid for later use;

[0047] Step B2: Add the modified liquid and dispersion liquid into the reactor, control the temperature at 67°C, stir at 300r / min, reflux for 5 hours, and when the reaction is complete, filter the reaction liquid with suction and put the filter cake in a vacuum drying oven for control The drying temperature is 50° C., and drying is carried out to constant weight to obtain modified calcium carbonate whiskers.

Abstract

The invention discloses a heat preservation method for a land-based fishing ground, belongs to the technical field of aquaculture, and solves the technical problems that in the prior art, a fishpond culture capital construction project is large, and an existing waterproof film is poor in performance. Hot-dip steel pipes are welded to serve as a pond wall structure, heat preservation cotton is laid on the pool bottom, then a waterproof film is laid on the heat preservation cotton, finally, a cold and hot water pipeline and an oxygenation pipeline are laid on the waterproof film, building of the heat preservation land-based fishing ground is completed, the construction period is short, and maintenance is easy. The invention also provides a preparation method of the waterproof membrane, the waterproof membrane is prepared by blending PVC, PVDF and butyl rubber to obtain a sizing material, good comprehensive properties of water resistance, aging resistance, toughness and plasticity are obtained, and the hardness and wear resistance of the waterproof membrane are improved by adding the modified calcium carbonate whisker and utilizing the characteristics of high elongation and high elastic modulus of the modified calcium carbonate whisker; and a nylon net is arranged in the waterproof film to prevent the waterproof film from deforming, so that the waterproof film has good tensile property and tear resistance.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a heat preservation method for a land-based fishery. Background technique [0002] Due to the increasingly serious problems of water environment pollution and eutrophication in the watershed, traditional watershed aquaculture makes aquatic products susceptible to disease. Therefore, the aquaculture method of land-based fish farms is gradually flourishing. The most common implementation method of land-based fish farms is fish pond aquaculture. In the early stage of construction, a large number of infrastructure projects need to be done, such as land hardening, cement brick concrete insulation layer masonry, etc., the construction period is long and labor-intensive; at present, there are also fish pond breeding methods that use waterproof membranes and frames. In the state of water pressure, it is necessary to have good stretch resistance, tear resistance, wear resi...
