preparation example Construction

[0031] The preparation method of the present invention's bottoming decorative putty is:

[0032] Weigh each component of the primer decorative putty by weight percentage, put 200 mesh quartz sand, cellulose ether, waste paper fiber, sodium polyacrylate, active material and pigment into a high-speed mixing machine with a speed of 1300r / min and a volume of 200L Mix in the machine for 3 minutes to prepare the mixture, release it for later use; put the aluminate cement, acrylic acid redispersible latex powder, filler, zeolite powder and the mixture into the mortar mixer, add water and mix for 3 minutes to obtain the base decorative putty.

[0033] See Table 1 with the performance of the primer putty prepared by the present invention:

[0034] Table 1: The performance index of the primer putty prepared by the present invention

[0035]

[0036] The above experiments refer to the following standards: "Flexible Putty for Exterior Walls" (GB / T 23455-2009), "Primers for Building In...

Abstract

The invention discloses a heat insulation system decorative surface structure which comprises, from inside to outside, a heat insulation layer, an anti crack layer, a putty layer and a decorative surface coating layer; the putty layer is a layered structure formed by mixing base decoration putty and water and applying the mixture to the anti crack layer; the base decoration putty comprises the following components: 10-25% of aluminate cement, 8-25% of acrylic redispersible latex powder, 20-40% of 200 mesh quartz sand, 10-25% of a filler, 2-4% of zeolite powder, 0.2-0.5% of cellulose ether, 0.3-0.6% of waste paper fiber, 0.01-0.05% of sodium polyacrylate, 0.5-2% of active substances and 0-5% of a pigment. Compared with the prior art, a closed primer layer is reduced, cost is reduced, the putty layer has good flexibility, cracking resistance, construction smoothness, alkali burnout resistance and water resistance, can replace a traditional putty layer and primer layer, reduces the use of the primer layer, reduces primer cost and labor cost, has long-term weather resistance, and provides a decorative effect.

Description

technical field [0001] The invention relates to the technical field of building exterior wall decoration, in particular to a decorative surface structure of a thermal insulation system. Background technique [0002] Putty is a kind of decorative concrete material for leveling the surface of the wall, and it is an indispensable product before painting. Apply to the mortar or directly to the object to remove uneven defects on the surface of the object to be coated. The product forms of putty mainly include powder putty and paste putty. The main components of powder putty are cement, filler, thickener, redispersible latex powder, etc. Paste putty is mainly composed of emulsion, admixture, filler or cement in proportion, the main function is to level and prevent cracking. There are few decorative effects. [0003] The general method of facing the thermal insulation system is to scrape and coat the flexible water-resistant putty layer on the anti-crack mortar leveling layer of...
