Abstract

The utility model relates to construction components which are light energy saving building blocks made of waste plastics. The light energy saving building blocks are made of all waste plastics, having light weight and head isolation. The building blocks are composed of a plurality of face material layers and base material layers whose faces are prefabricated with cement, the base material layers are made of fly ash of 35-55%, the cement of, 15-35% and the waste plastics of 25-45% which are mixed, the base material layers are added with one or a plurality of kinds of fibre materials of 3-5%, and the one or a plurality of kinds of fibre materials in the base material layers can be mineral fibres or plant fibres, such as glass fibres, asbestos fibres or wood fibres.

Description

The light energy conservation building block

The utility model relates to buiding material members, is a kind of light energy conservation building block made from waste plastics.

Waste plastic can be divided into thermosetting and thermoplastic two big classes.At present, with the waste plastic is light energy-saving brick or the plate that raw material is made, general all is to adopt single waste plastic, as foamed plastic, this just utilizes and has handled few part waste plastic, the product that makes can only reach lightweight and warming effect, and produces required raw material sources and extremely lack; In addition, very loaded down with trivial details and complicated to the classification processing and the treatment process of the waste plastics that utilized, increased cost of production, thereby producer can't accept; Owing to the limitation of material utilization, its product of making all can not reach the technical indicator that the load-bearing fragment of brick requires, and generally can only be used to do sheet material or inserts warming, heat insulation, sound insulation besides.

The purpose of this utility model provides a kind of light energy conservation building block, and it can adopt all waste plastics to manufacture, and the product lightweight thermal, also can reach the requirement of bearing building block.

The purpose of this utility model reaches by following technical measures: the building block of geometry is by being shaped on the cement precoat in advance on a plurality of and binder layer constitutes.Binder layer is mixed by 35～55% flyash, 15～35% cement and 25～45% waste plastics, also adds one or more fibrous materials of 3～5% in the binder layer.

One or more fibrous materials in the described binder layer can be earlier with mineral fibers or string, as glass fiber, asbestos fiber or wood fibre.

The utility model is described in further detail below in conjunction with embodiment and accompanying drawing thereof.

Fig. 1 is the schematic diagram of the utility model embodiment.Fig. 2 is the A-A sectional drawing of Fig. 1.

As shown be a building block of making hollow support body, its surface is cement precoat (1), and inside is binder layer (2).Binder layer is mixed by 35～55% flyash, 15～35% cement and 25～45% waste plastics, also adds one or more fibrous materials (3) of 3～5% in the binder layer.The raw material of above-mentioned composition is mixed by proportioning, put into mould after the water of adding raw material gross weight 18～25% stirs, at 7～9 kilograms forming under the pressure; Also can prolong moldedly by up-down vibration, promptly get various geometries, as building block products such as groined type, rectangles.Light and the easy construction of the product good heat insulating that makes, body.

Because the utility model can adopt all waste plastic manufacturings such as thermoplasticity and thermosetting, thereby raw material wide material sources, and can more effectively eliminate white pollution, again owing to do not need waste plastic classified and reclaim and handle, thereby can significantly reduce equipment investment, real small investment, instant effect, the high effect of repayment of realizing has good social benefit and economic benefit.The lightweight fragment of brick product that the utility model is made is economy but also can sound-insulation and heat-insulation not only, can also make the load-bearing fragment of brick, is fit to very much the use technological requirement of building trade.

Claims
