Abstract
The invention relates to interior wall putty powder which comprises the following components in parts by weight: 1020 portions of coarse whiting powder, 8-10 portions of pregelatinized starch, 2-5 portions of polyvinyl alcohol powder and 4.5-5.5 portions of cellulose ether. The putty powder is prepared by adding polyvinyl alcohol powder and cellulose ether into coarse whiting powder to prepare interior wall putty powder, the obtained quality is far superior to that of common putty powder of starch and 821, meanwhile, the hardness of the interior wall putty powder is between that of gray calcium-based putty and starch putty, and the interior wall putty powder also has excellent scraping property, and the two kinds of putty have far inferior adhesive force, flexibility, polishing fineness and durability; the components of the formula are simple and feasible.
Description
Technical Field
The invention belongs to the technical field of building materials, and particularly relates to interior wall putty powder.
Background
The putty powder is a decorative material for leveling wall surface, is made up by using inorganic gel material as aggregate, adding adhesive material and other auxiliary agent and adopting fine processing process, and is an indispensable product before painting, and is a surface filling material for pretreating construction surface. The putty powder is divided into an outer wall and an inner wall, and the quality of the putty powder for the inner wall directly influences the decorative effect of painting the inner wall. The existing interior wall putty powder has complex components.
Disclosure of Invention
The invention aims to provide interior wall putty powder, which not only meets the performance of interior wall putty powder, but also simplifies the components of the interior wall putty powder, and simultaneously has excellent batch scraping property.
Therefore, the technical scheme adopted by the invention is that the interior wall putty powder comprises the following components: heavy calcium powder, pregelatinized starch, polyvinyl alcohol powder and cellulose ether.
According to one embodiment of the application, the composition comprises the following components in parts by weight: 1020 portions of coarse whiting powder, 8-10 portions of pregelatinized starch, 2-5 portions of polyvinyl alcohol powder and 4.5-5.5 portions of cellulose ether.
In the scheme, the pregelatinized starch can be quickly dissolved in cold water to form high viscosity, has strong bonding force, can thicken and protect the shape, and has high strength after molding, namely the pregelatinized starch has the functions of enhancing the bonding force and improving the strength.
The adhesive strength of the polyvinyl alcohol powder is 2.5-3 times higher than that of redispersible latex powder, and the polyvinyl alcohol powder has good film forming property in the putty powder, and can be used together with cellulose ether water-retaining agents to improve the flexibility and water-retaining property of various cement mortar and gypsum building materials, improve the adhesive strength of the mortar and effectively prevent peeling, cracking and hollowing. If the content is less than 2 parts, the performance of the interior wall putty cannot be guaranteed, and if the content is more than 5 parts, part of the interior wall putty is not dissolved, and the undissolved colloidal particles can cause the phenomena of putty batch scraping and sticking knife, colloidal particles after polishing or difficulty in polishing and polishing.
Preferably: the polyvinyl alcohol powder is a high-viscosity polyvinyl alcohol powder, and the particle size thereof must be 200 mesh or more. When the particle size of the polyvinyl alcohol powder reaches more than 200 meshes, the solubility of the polyvinyl alcohol powder is better, the utilization rate of the polyvinyl alcohol powder is increased, and the performance of the produced product is more stable.
Preferably: the cellulose ether is hydroxypropyl methyl cellulose ether. The water retention property of the hydroxypropyl methyl cellulose HPMC enables the sizing agent not to crack because of drying too fast after being coated, and enhances the strength after hardening.
Preferably: the pregelatinized starch is preferably corn pregelatinized starch.
The invention has the beneficial effects that: the putty powder is prepared by adding polyvinyl alcohol powder and cellulose ether into coarse whiting powder to prepare interior wall putty powder, the obtained quality is far superior to that of common putty powder of starch and 821, meanwhile, the hardness of the interior wall putty powder is between that of gray calcium-based putty and starch putty, and the interior wall putty powder also has excellent scraping property, and the two kinds of putty have far inferior adhesive force, flexibility, polishing fineness and durability; the components of the formula are simple and feasible.
Detailed Description
The present invention is further illustrated by the following examples.
Example 1
The interior wall putty powder comprises the following raw materials in parts by weight: 980 parts of heavy calcium powder, 8 parts of corn pregelatinized starch, 2 parts of high-viscosity polyvinyl alcohol powder with the particle size of more than 200 meshes and 4.5 parts of hydroxypropyl methyl cellulose ether.
Example 2
The interior wall putty powder comprises the following raw materials in parts by weight: 1020 parts of heavy calcium powder, 10 parts of corn pregelatinized starch, 5 parts of high-viscosity polyvinyl alcohol powder with the particle size of more than 200 meshes and 5.5 parts of hydroxypropyl methyl cellulose ether.
Example 3
The interior wall putty powder comprises the following raw materials in parts by weight: 1000 parts of heavy calcium powder, 9 parts of corn pregelatinized starch, 3 parts of high-viscosity polyvinyl alcohol powder with the particle size of more than 200 meshes and 5 parts of hydroxypropyl methyl cellulose ether.
Example 4
The interior wall putty powder comprises the following raw materials in parts by weight: 1010 parts of heavy calcium powder, 9.5 parts of corn pregelatinized starch, 4 parts of high-viscosity polyvinyl alcohol powder with the particle size of more than 200 meshes and 5.2 parts of hydroxypropyl methyl cellulose ether.
The interior wall putty powder prepared in the above examples 1 to 4 was subjected to performance testing according to the method for detecting interior wall putty powder of general type (Y) in the industry Standard JG/T298-2010 putty for interior buildings, and the results of the performance testing are shown in Table 1.
TABLE 1
From Table 1, it can be seen that the interior wall putty powders prepared in examples 1-4 all meet the technical requirements of general type (Y) in the industrial standard JG/T298-2010 putty for building interior.
