Embodiment Construction

[0017] like figure 1 As shown, the thermal insulation wallboard of the present invention is covered with a layer of shell 1 on the outer surface of the polystyrene foam board 2, and the shell 1 is made of a layer of alkali-resistant glass fiber mesh 4, 30-40 parts (weight) of fly ash, The mixed slurry solidified layer 3 is formed by mixing 60-70 parts (weight) of ordinary portland cement, 10 parts of construction adhesive and 1 part of auxiliary agent.

Abstract

The invention discloses a fly ash light-weight and heat-preservation wallboard and a manufacturing method thereof. The method comprises the following steps: a polyphenyl cystosepiment is put in a mould; mixed slurries with the thickness of 0.5cm, alkali resistant glass fiber mesh and the mixed slurries with the thickness of 0.5cm are paved on the polyphenyl cystosepiment evenly in sequence; the periphery space of the polyphenyl cystosepiment and the mould is infilled with the mixed slurries and finally the cystosepiment is packaged in the middle and demoulds after solidifying for 3 to 4 hours; and then the wallboard can be manufactured well after air-curing is carried out for 5 to 10 days. The mixed slurries are made by mixing fly ash waste, portland cement, construction adhesive, assistant and water. The wallboard has lighter weight, is easy for transport and installation, fully utilizes industrial residue and reduces environment pollution.

Description

technical field [0001] The invention relates to building materials, in particular to a manufacturing method of a lightweight thermal insulation wallboard. Background technique [0002] Present thermal insulation wallboards are generally made of hydraulic materials into a hollow shape, although they are hollow, they still weigh a lot. [0003] At present, some industrial wastes such as fly ash and cinders generally have to be thrown away, which is a pity. Also do not find the light-weight insulation quality wallboard that fly ash slag and polystyrene foam are made at present. Contents of the invention [0004] In order to solve the problem of the weight of the thermal insulation partition board and make full use of industrial waste, the invention proposes a light thermal insulation wall board made of industrial waste fly ash and polystyrene foam and a manufacturing method thereof. [0005] A kind of fly ash slag light insulation wallboard, it is characterized in that, be ...
