Embodiment Construction

[0026] The invention discloses a novel production method of vacuum heat insulation panels, a production method of novel vacuum heat insulation panels. The core material is put into a high-barrier gas film bag, and sealed after vacuuming. It is characterized in that the composition of the core material and The parts by weight are: microsilica powder 10-14, fumed silica 15-18, white carbon black 5-8, superfine natural silica powder 8-10, inorganic fiber 5-7, vacuum stabilizer 1-2 , getter 1-2;

[0027] The manufacturing process includes the following steps:

[0028] (1) Ingredients: Put various materials of the formula into the mixer for full mixing;

[0029] (2) Drying: Dry the evenly stirred mixture, and control the drying temperature at 100-120°C. During the drying process, measure the moisture content of the mixture every 8 minutes until the moisture content of the mixture reaches 0.5 % below, stop drying;

[0030] (3) Bag making and filling: Put the dried mixture into th...

Abstract

A production method of a novel vacuum insulated panel has the processing steps: feeding fumed silica, silica micropowder, silica fume, aerogel, fibers and a vacuum active stabilizer in a mixer to fully mix to obtain a mixture, drying the uniformly stirred mixture, forming core material, that is, feeding the dried mixture and a degasser in a die, and putting the die in a press for pressure forming; wrapping: taking out cross-band veneer formed through pressing of the die, and wrapping a layer of non-woven fabrics on the periphery of the core-band veneer so as to obtain the vacuum insulated core-band veneer for buildings; putting the core-band veneer in a high-resistance air film bag for vacummizing, wherein the vacuum degree is 0.02 to 20 Pa, and sealing. The production method has the advantages that the fibers as well as the fumed silica, silica micropowder, silica fume and aerogel are mixed to improve the strength of the insulated panel, the thermal conductivity of the core material is lower, the core material is an inorganic material, and is not easy to burn, the prices of raw materials are lower, the costs of the raw materials are reduced, and the environmental pollution is reduced.

Description

technical field [0001] The invention relates to a production method of a novel vacuum heat insulation panel, which is used for producing the vacuum heat insulation panel, which is used as a building or industrial heat preservation material. Background technique [0002] Existing vacuum insulation panels are mainly composed of internal heat-insulating core material and outer high-barrier film, in which the heat-insulation core material is generally made of conventional thermal insulation materials (such as foamed plastics), glass fiber or / and airgel, etc. Its disadvantages are high material cost, high energy consumption and not environmental protection. Contents of the invention [0003] The invention aims to provide a novel production method of vacuum insulation panels to solve the problems of high material cost, high energy consumption and environmental protection in the prior art. [0004] The technical solution of the present invention is: a novel production method of ...
