Embodiment 1

[0045] Embodiment 1 (mixed material viscosity value is 10000~100000cps):

[0046] Add 100 parts of bisphenol A liquid epoxy resin E~51, 75 parts of methyltetrahydrophthalic anhydride MeTHPA, 0.2 parts of silane coupling agent KH~550, and 0.5 parts of wetting and dispersing agent into the container, and use high Stir with a constant speed mixer with shear force, such as a dough mixer or a planetary mixer. After stirring evenly, add 50 parts of glass hollow microspheres. After stirring well, add 40 parts of glass hollow microspheres in batches and stir evenly. Use the feeding method 1 to pump the mixed material through the material inlet 9 through the pressure pump figure 1 In the devices shown, the retaining nuts on the devices are determined to be at maximum slack. Seal the material inlet 9 and the air outlet 8, and then tighten the fastening nuts 10 evenly.

[0047] Put the mixed material together with the equipment into the oven for heating and curing. The curing process i...

Embodiment 2

[0051] Embodiment 2 (when the viscosity value of the mixed material is 100000~250000cps):

[0052] Heat 100 parts of bisphenol A liquid epoxy resin E~51 to 75~80°C, add 0.2 parts of silane coupling agent and 0.5 parts of wetting and dispersing agent and stir evenly; add 80 parts of glass hollow microspheres into the resin in batches , Stir evenly with a high-shear constant-speed stirrer; heat 30 parts of aromatic amine curing agent diaminodiphenylmethane to 85-90°C, and after the solid diaminodiphenylmethane is completely melted, quickly add it to the previous mixing In the good material, stir evenly. Close the material inlet and air outlet, and add the mixed material into the figure 1 in the device shown. Specifically: open the fixing bolts, remove the pressure metal cover and pressure adjustment layer, fill the material into the equipment, install the pressure adjustment layer after filling, cover the pressure metal cover, screw on the bolts, and then put the nuts evenly ...

Abstract

The invention provides a preparation method of a polymer matrix light pressure resistant floating material and a piece of equipment thereof, which can solve the problems of high content of bubbles, difficulty in removing such bubbles and thus poor performance existing in the prior art. The adopted technical proposal lies in that the method includes four steps: mixing and stirring, adding in the equipment, solidification by heating and knockout; the equipment is provided with a pressure regulating layer, in which continuous pressure is added to the material being solidified, so that the bubbles mixed in the materials can be pushed out timely; therefore, the obtained polymer matrix light pressure resistant floating material has the advantages of dense and even texture, no bubble, high compressive strength, low water absorption and stable performance.

Description

technical field [0001] The invention relates to a lightweight material capable of providing net buoyancy used in marine development, in particular to a preparation method and equipment for making a polymer-based lightweight pressure-resistant buoyancy material for deep-sea operations. Background technique [0002] The polymer-based lightweight pressure-resistant buoyancy material is a composite material obtained by filling hollow glass microspheres into a resin matrix, filling the mixture into equipment, and curing the resin matrix. This composite material has obvious advantages over traditional foam plastics. The reason is as follows: the cell structure of the polymer-based lightweight pressure-resistant buoyancy material is provided by the cavity in the middle of the glass hollow microsphere, while the foam structure of the traditional foam plastic is obtained by physical or chemical foaming. The ideal polymer-based lightweight pressure-resistant buoyancy material is supp...
