Problems solved by technology

[0002] At present, the traditional putty powder and putty paste products on the market have low bonding strength, are not water-resistant, easy to powder, easy to mildew, and easy to fall off, which brings troubles to the secondary decoration and increases the frequency of renovation.
Although the traditional putty powder has reached the strength, water resistance, sanding and other indicators stipulated in the relevant national standards, most of the gaps between the particles of the putty powder are large, there are many pores, and the density is not dense enough, resulting in too coarse sanding traces. The surface is rough, not delicate, not smooth, and has many pinholes, which is not conducive to the subsequent wall paint spraying construction, and the decorative effect is not good
Some traditional putty pastes also use harmful substances such as formaldehyde, which has poor environmental protection performance.

Embodiment 1

[0030] Get the following raw materials: 325 mesh heavy calcium carbonate 20kg, 325 mesh sodium bentonite 2kg, 400 mesh talcum powder 30kg, 425# white cement 28.5kg, 400 mesh calcium hydroxide 175kg, 125 mesh polyvinyl alcohol 1788 powder 1.0kg, 0.35 kg of hydroxypropyl methylcellulose and 0.2 kg of 100-mesh sodium hexametaphosphate powder are put into a dry powder mixer and stirred for 30 minutes until they are evenly mixed.

[0031] The putty powder prepared above was subjected to a water and crack resistance test, and the test results were compared with the national standards in the following table:

[0032] Test group number

[0033] It can be seen from the table that the water resistance, wear resistance and crack resistance of the putty powder in this embodiment are much higher than the national standard values.

Embodiment 2

[0035] Get the following raw materials: 325 mesh heavy calcium carbonate 30kg, 325 mesh sodium bentonite 2.5kg, 400 mesh talcum powder 25kg, 425# white cement 20kg, 400 mesh calcium hydroxide 20kg, 120 mesh polyvinyl alcohol 1788 powder 1.8kg, 2.5kg of hydroxypropyl methylcellulose, 0.2kg of 100-mesh sodium hexametaphosphate powder, 0.3kg of 600-mesh tourmaline powder, put each raw material into the dry powder mixer and stir for 30 minutes, and mix evenly.

[0036] With the putty powder of the present embodiment, carry out anion detection test by the relevant national standard JC / T1016-2006 " test method of material anion generation amount ", test result putty powder anion release amount of the present invention is 1166 / s cm 2 , not generally 100-200 / s cm indoors without using the putty powder of the present invention 2 , after using this product, the negative ion content in the indoor air will be much higher than that in the general indoor air, and its environmental protectio...

Embodiment 3

[0038] Get the following raw materials: 325 mesh heavy calcium carbonate 10kg, 325 mesh sodium bentonite 3kg, 400 mesh talcum powder 50kg, 425# white cement 10kg, 400 mesh calcium hydroxide 25kg, 120 mesh polyvinyl alcohol 1788 powder 1.4kg, hydroxyl Propyl methyl cellulose 0.2kg, put each raw material into the dry powder mixer and stir for 30 minutes, mix evenly and get final product.

Abstract

The invention provides putty powder used for walls in a house. The putty powder comprises the following ingredients: ground calcium carbonate, sodium-base bentonite, 1788 powder of polyving akohol, hydroxypropyl methyl cellulose and talcum powder, besides, white cement or/and calcium hydroxide powder is/are added therein as a reinforcing material, and also, sodium hexametaphosphate powder and/or tourmaline powder are/is added in the product. The putty powder has excellent scraping construction performance, long-acting mould-proof performance and excellent dense degree of the putty coating as well as the function of releasing negative ions for a long time, can effectively adsorb various harmful substances in the air and purify the air, and has excellent environment-friendly performance.
