Embodiment Construction

[0008] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0009] figure 1 As shown, a new type of marine cold storage installation composite plate includes an upper protective layer 1, a middle thermal insulation layer 2 and a lower base material layer 3, and the upper protective layer 1, the middle thermal insulation layer 2 and the lower base material layer 3 are stacked sequentially from top to bottom, The middle insulation layer 2 is a modified phenolic resin foam insulation layer. The thickness of the middle insulation layer is 20-150mm. Layer 3 is a protective surface layer of galvanized steel plate or stainless steel or color steel plate or aluminum plate, and the thickness of the lower substrate layer is 0.05-0.5 mm.

[0010] The preparation method of the marine new-type cold storage installation composite plate of the present invention is: cutting the upper protective layer and the lower bas...

Abstract

The invention relates to a method for preparing a novel cold storage installation composite board for ships. The method comprises the following steps: manufacturing an upper protective layer and a lower base material layer according to the dimension of the composite board, heating and mixing an expandable modified phenolic resin, a surfactant, a foaming agent, a curing agent and an auxiliary at the temperature of 25-60 DEG C, spraying the mixture between the upper protective layer and the lower base material layer through a high-pressure spray gun, emulsifying, forming and holding the temperature for 24 hours through equipment of a continuous production line, and demoulding, thereby obtaining the composite tube, wherein the mass ratio of expandable modified phenolic resin to the surfactant to the foaming agent to the curing agent to the auxiliary is 100:4:5:25:5; the surfactant is a general surfactant of silicane and tween series; the foaming agent is a NaCO or metal powder general solid foaming agent; the curing agent is hydrochloric acid or sulfuric acid or phosphoric acid; the auxiliary is boracic acid or urea or antimony oxide.

Description

technical field [0001] The invention relates to a composite thermal insulation board, in particular to a method for preparing a metal-faced phenolic composite thermal insulation board suitable for thermal insulation boards such as cold stores in the shipbuilding industry. Background technique [0002] As an indispensable and important part of the cold storage in the modern shipbuilding industry, the cold storage board has its materials and manufacturing technology constantly updated with the continuous progress and development of science and technology. For example, the heat insulation materials used in traditional bulk cold storage are rock wool or ultra-fine glass wool, which will produce harmful dust during processing and installation, which is harmful to the human body, has relatively poor heat preservation effect, and increases the weight of the hull. The assembled cold storage is assembled on-site with polyurethane composite module panels, which is simple and quick...
