Building appearance light-weight decorative member
Technical field
The utility model relates to a kind of building unit
Background technology
Come from human pursuit to U.S., the outer decoration of building receives publicity always.Along with the raising of economy, technology and art, my country development in the last few years on the outer decoration of new building thing is very fast.Outer motif in the past, lines use all is basic constructional materials such as concrete, and work progress is complicated, and the ratio of decoration is great.Therefore manually, the cost of the input of material is higher.
Summary of the invention
The purpose of this utility model provides a kind of low cost, simple installation, long-lived external surface of buildings light-weight decorative member, overcomes the aforementioned deficiency that building external decorative exists in the prior art.
External surface of buildings light-weight decorative member of the present utility model is made up of with the polymer mortar top layer that is coated in outer surface of matrix the matrix of polystyrene (EPS) expanded material.
The material on polymer mortar top layer is formed to be had:
1, by VAE emulsion (ethene-vinyl acetate copolymer emulsion) 500--700 weight portion, water 350--420 weight portion, modifier (cellulose ether 3--7 weight portion, wood fiber 0.5-1.5 weight portion), auxiliary agent (bactericide HF3-5 weight portion, defoamer 681F0.01-0.02 weight portion) mixes, and forms bonding agent.Again with above-mentioned bonding agent, the 425# quick hardening sulphoaluminate cement, quartz sand mixes in 1: 1.88: 3.25 ratio, promptly forms and is called three-component polymer mortar skin-material.
2, by acrylic resin 400-500 weight portion, fine sand 350-450 weight portion, modifier (calcium lignosulfonate 1-3 weight portion, dispersed 50401-3 weight portion, water 100-150 weight portion, wood fiber 12-17 weight portion), auxiliary agent (bactericide HF3-5 weight portion, defoamer 681F 0.03-0.06 weight portion) is formed bonding agent.With bonding agent, the 425# quick hardening sulphoaluminate cement mixes in 1: 1.1 ratio again, promptly forms and is called bi-component polymeric mortar skin-material.
3, by redispersible polymer powder 400-500 weight portion, cement 360-400 weight portion, quartz sand 140-160 weight portion, modifier (cellulose ether 4-6 weight portion, calcium lignosulfonate 46 weight portions) mixes, and mixture and water are being concocted in 100: 20 ratio.Promptly form and be called single polymer mortar skin-material.
More than be the utility model basic scheme.
For the intensity on increase decorative thread polymer mortar surface and the bonding fastness of mortar top layer and matrix, self-adhesion, alkali-resistant glass fibre grid cloth are arranged between EPS matrix and polymer mortar top layer.
Use good effect of the present utility model to be: decorative thread can be prefabricated, and be shaped easily.Body is light, convenient, difficult drop-off when bonding on building.Surface waterproofing, cracking resistance, flexible, shock resistance can have same application life with building.

The specific embodiment (building appearance light-weight decorative line)
Embodiment 1
Determine linear decoration member matrix 1 with the EPS plate by the profile that sets.Be stained with self-adhesion alkali-resistant glass fibre grid cloth 2 at EPS matrix combination with decorative surfaces, grid cloth mesh 2 * 2mm.Join again by VAE emulsion (ethene-vinyl acetate copolymer emulsion) 600 weight portions, water 390 weight portions, modifier (cellulose ether 5 weight portions, wood fiber 1 weight portion), auxiliary agent (bactericide HF4 weight portion, defoamer 681F 0.02 weight portion) mixes, and forms bonding agent., again with above-mentioned bonding agent, the 425# quick hardening sulphoaluminate cement, quartz sand mixes in 1: 1.88: 3.25 ratio, promptly forms to be called three-component polymer mortar skin-material.With skin-material with spray gun spraying or brushing, holiday to the decorative thread matrix surface, applied thickness 2.5-5mm forms polymer mortar top layer 3.When half-dried, again light is scraped on the polymer mortar surface, promptly finished manufacturing of the utility model decorative thread.
Embodiment 2
By acrylic resin 450 weight portions, fine sand 400 weight portions,, modifier (calcium lignosulfonate 2 weight portions, dispersed 50402 weight portions, water 130 weight portions, wood fiber 15 weight portions), auxiliary agent (bactericide HF 4 weight portions, defoamer 681F 0.05 weight portion) is formed bonding agent.Bonding agent, 425# quick hardening sulphoaluminate cement are mixed in 1: 1.1 ratio again, promptly form and be called bi-component polymeric mortar skin-material, other processes are with embodiment 1.
Embodiment 3
By redispersible polymer powder 450 weight portions, cement 380 weight portions, quartz sand 160 weight portions, modifier (cellulose ether 5 weight portions, calcium lignosulfonate 5 weight portions) mixes, and mixture and water is concocted in 100: 20 ratio again.Promptly form and be called single polymer mortar skin-material, other processes are with embodiment 1.
This decorative thread is with the bonding agent that provides in the present specification decorative thread to be bonded to desired location toward the fixing means on the building.
