Problems solved by technology

In the above-mentioned prior art, components such as diatomaceous earth make the putty layer have a better effect of absorbing formaldehyde in the air, and calcium oxide improves the self-strength of the putty after the reaction, which makes up for components with lower viscosity such as diatomaceous earth. The impact on the strength is to ensure that the putty layer does not lose powder or peel; however, when calcium oxide meets water and carbon dioxide, it will produce calcium hydroxide with a certain degree of alkalinity, and this alkalinity will generally last for 5-7 days before disappearing If this alkalinity is not well controlled, it will make the builder feel burning, and it is easy to burn the skin of the builder during the construction process.

Embodiment

[0029] Embodiment: the quality of each component is as shown in table 1 in each embodiment.

[0030] Table 1

[0031]

[0032]

[0033] Among the above components, diatomite has a mesh number of 1000 mesh and a whiteness of 96%; 2488 polyvinyl alcohol has a mesh number of 120-200 mesh.

[0034] After fully mixing the neutral environment-friendly putty of Examples 1-5 with water according to the mass ratio of 1:0.4, the mixture is coated on a plane, and it can be observed that the neutral environment-friendly putty has good whiteness before and after mixing with water . Then its performance was tested according to the standard of "Putty for Building Interiors" (JG / T298-2010), and the test results are shown in Table 2.

[0035] Table 2

[0036]

[0037] It can be seen from Table 2 that Example 2 has better performance when no white carbon black is added, so Example 2 is a more preferred solution when no white carbon black is added. The neutral environment-friendly p...

Abstract

The invention discloses a neutral environment-friendly putty which comprises the following components in parts by weight: 100-150 parts of white cement, 630-660 parts of heavy calcium carbonate powder, 140-190 parts of adsorptive filler, 0.1-1 part of edible seaweed powder, 1.4-2 parts of polyvinyl alcohol, 3-3.7 parts of hydroxypropyl methylcellulose and 0.9-1.2 parts of hydroxypropyl starch ether. The neutral environment-friendly putty has the advantages of high safety and favorable environment friendliness, and has favorable capacity for improving the environment quality.

Description

technical field [0001] The invention relates to the technical field of building materials, more specifically, it relates to a neutral environment-friendly putty. Background technique [0002] Putty is a commonly used building material for interior decoration. It is located between the wall leveling mortar and the paint layer, and plays an auxiliary role in further leveling and forming decorative texture patterns. With the vigorous development of building interior decoration, users have higher and higher safety requirements for putty products during construction; and because after interior decoration, there will be harmful gases released by household decoration products in the room, so the safety and environmental protection of putty products itself There are higher requirements for safety and the improvement of environmental quality. [0003] At present, the Chinese patent with the authorized notification number CN102850835B discloses a putty powder for adsorbing impurity g...
