Embodiment 1

[0020] Weigh 300 grams of epoxy resin, 70 grams of epoxy reactive diluent, and 12 grams of silane coupling agent into a premix tank equipped with a stirrer, stir the materials evenly at room temperature, and put them into 280 grams of graded hollow Glass beads, mixed at a slow speed to form "bean dregs", put the materials into the kneader, and knead for 15 minutes. Add 180 grams of 3,3 ， -Diethyl 4,4,-diaminodiphenylmethane curing agent, continue kneading for 40 minutes until the material has a "dough" shape. The discharged material is filled into a mold, hot-pressed and solidified on a flat vulcanizing machine, and after demoulding, it is post-cured at 140°C for 4 hours to obtain a solid buoyancy material blank. Its product material density is 0.507g / cm 3 , The uniaxial compressive strength is 30.15Mpa, and the volume fraction of hollow glass microspheres is 64.0%.

Embodiment 2

[0022] Take by weighing 240 grams of epoxy resin, 60 grams of epoxy reactive diluent, and 12 grams of silane coupling agent, put into the premix tank equipped with agitator, stir the material evenly at room temperature, drop into 220 grams of graded Hollow glass microspheres, mixed at a slow speed to form "okara" shape, put the material into the kneader, and knead for 15 minutes. Add 86 grams of isophorone diamine curing agent and continue kneading for 40 minutes until the material becomes "dough". The discharged material is filled into a mold, hot-pressed and solidified on a flat vulcanizing machine, and after demoulding, it is cured at 120°C for 4 hours to obtain a solid buoyancy material blank.

Abstract

The invention discloses a solid buoyancy material and a manufacture method thereof by splitting building block type modules. The manufacture method comprises the steps of: polishing and finishing a buoyancy material blank, machining to manufacture a building block type standard module, and manufacturing the solid buoyancy material from the splitting building block type standard module through finish machining. The solid buoyancy material comprises the following chemical components in parts by mass: 100 parts of epoxy resin, 20-25 parts of epoxy reactive diluents, 40-80 parts of curing agent, 3-5 parts of silane coupling agent and 85-100 parts of hollow glass beads. According to the invention, the building block type modules are adhered by adopting a light adhering agent, and thus the prepared solid buoyancy material has good comprehensive property, is applied flexibly, is conveniently produced according to the density, the size and the shape required by a user, and is suitable for different use occasions.

Description

technical field [0001] The invention relates to a solid buoyancy material and a manufacturing method thereof. Background technique [0002] In the 1960s, the U.S. Naval Applied Science Laboratory began to develop solid buoyancy materials. When the material density was 0.35g / cm 3 , the uniaxial compressive strength is 5.5Mpa. Solid buoyancy material for 7,000-meter manned submersible developed by Emerson & Cuming of the United States, with a density of 0.5g / cm 3 At this time, it can dive to a depth of 7000 meters. The preparation method of solid buoyant material is reported more, and U.S. Patent USP4829094, USP4843104, USP4902722, USP4916173, USP4595623, USP6166109 have reported some solid buoyant materials prepared by different methods, including chemical foaming foam material, copolymer foam material, syntactic foam material . [0003] USP4,021,589, USP5,973,031 report a buoyancy material made of hollow glass microspheres filled with unsaturated polyester resin. Unsatu...
