Embodiment 1

[0010] A method for making thermal insulation boards from waste foam glass, which is characterized in that foam glass fragments, foam glass powder, cellulose, rubber powder, cement and lime are mixed evenly with water, cast into a rectangular body by using a mold, and cut into pieces after natural drying Plate-shaped recycled material finished product, the weight ratio of the above foam glass fragments is 64%, the block diameter is 30mm-150mm, the weight ratio of foam glass powder is 16%, the weight ratio of cellulose is 0.24%, the weight ratio of rubber powder The weight ratio of cement is 0.12%, the weight ratio of cement is 15%, and the weight ratio of lime is 4.64%.

[0011] Above-mentioned embodiment has adopted the cellular glass fragment of different sizes,

Embodiment 2

[0015] Divide the rectangular body poured by the above method into recycled material sheets, place two recycled material sheets on the upper layer and the lower layer, sandwich a layer of non-recycled material sheets in the middle, and glue them together to make a finished composite insulation board. The indicators are shown in Table 2:

Abstract

The invention discloses a method for manufacturing a heat-preservation plate by using a foam glass waste material. The method is characterized by comprising the following steps: uniformly stirring foam glass fragments, foam glass powder, cellulose, rubber powder, cement and lime by using water, pouring to obtain a rectangular body by using a mold, naturally drying, and then slitting into a platy reclaimed material finished product, wherein the weight percentage of the foam glass fragments is 60-65%; the block diameter of each foam glass fragment is 30-150mm; the weight percentage of the foam glass powder is 15-17%; the weight percentage of cellulose is 0.2-0.3%; the weight ratio of the rubber powder is 0.1-0.15%; the weight percentage of the cement is 14-16%; the weight percentage of lime is 4-5%; meanwhile, a reclaimed material and a non-reclaimed material are compounded, so that each performance index can be further improved, and more application requirements can be met. More importantly, the method disclosed by the invention is used for creatively solving the difficulties of recycling foam glass fragment wastes, and has economic and social benefits.

Description

technical field [0001] The invention relates to a method for making a heat preservation board, in particular to a method for making a heat preservation board by using foam glass waste. Background technique [0002] The foam glass plate is an inorganic non-metallic glass material made of cullet, foaming agent, modified additive and foaming accelerator, etc., after finely pulverizing and uniformly mixing, then melting at high temperature, foaming and annealing. A light-weight building material with superior performance in heat insulation (cold preservation), sound absorption, moisture resistance and fire prevention. It is very brittle, and a large number of fragments of foam glass are formed in the process of production, transportation and sales. This fragment of foam glass cannot be recycled and utilized, causing waste pollution. Contents of the invention [0003] The purpose of the present invention is to address the above problems, to propose a method for waste utilizati...
