preparation example Construction

[0024] The preparation method of fiber-reinforced plastering mortar specifically comprises the following steps:

[0025] Step 1. First mix diatomite with modified nano-titanium dioxide, then add triethanolamine whose mass is 1% of the mass of modified nano-titanium dioxide as a dispersant, fully grind and mix diatomite, modified nano-titanium dioxide and triethanolamine Uniform, prepared modified nano-titanium dioxide / diatomite composite photocatalyst;

[0026] Step 2, then mix cement, polypropylene fibers, inorganic pigments and the modified nano-titanium dioxide / diatomite composite photocatalyst prepared in step 1 evenly, then add water to stir, stir evenly to fully disperse the polypropylene fibers, A fiber-reinforced rendering mortar is obtained.

Embodiment 1

[0028] A fiber-reinforced plastering mortar, the following raw materials are weighed in parts by weight, 150 parts of Portland cement P Ⅰ 42.5, 180 parts of diatomaceous earth, 15 parts of iron ion modified nano-titanium dioxide, 0.8 part of engineering polypropylene fiber, 8 parts iron oxide and 280 parts water.

[0029] The preparation method of the above-mentioned fiber-reinforced plastering mortar is as follows: step 1, first mix diatomite with iron ion modified nano-titanium dioxide, then add triethanolamine whose mass is 1% of the mass of iron ion-modified nano-titanium dioxide as a dispersant, and silicon The algal earth, iron ion-modified nano-titanium dioxide and triethanolamine are mixed and ground evenly in an ultra-fine stirring mill to prepare an iron-ion-modified nano-titanium dioxide / diatomite composite photocatalyst;

[0030] Step 2: Put Portland cement P Ⅰ 42.5, engineering polypropylene fiber, iron oxide and the ferric ion-modified nano-titanium dioxide / diato...

Embodiment 2

[0032] A fiber-reinforced plastering mortar, the following raw materials are weighed according to parts by weight, 200 parts of Portland cement P Ⅱ 42.5, 150 parts of diatomaceous earth, 18 parts of iron ion modified nano-titanium dioxide, 1.2 parts of engineering polypropylene fiber, 6 parts chromium oxide and 250 parts water.

[0033] The preparation method of the above-mentioned fiber-reinforced plastering mortar is as follows: step 1, first mix diatomite with iron ion modified nano-titanium dioxide, then add triethanolamine whose mass is 1% of the mass of iron ion-modified nano-titanium dioxide as a dispersant, and silicon The algal earth, iron ion-modified nano-titanium dioxide and triethanolamine are mixed and ground evenly in an ultra-fine stirring mill to prepare an iron-ion-modified nano-titanium dioxide / diatomite composite photocatalyst;

[0034] Step 2. Put Portland cement P·Ⅱ42.5, engineering polypropylene fiber, chromium oxide and the ferric ion-modified nano-tita...

Abstract

The invention discloses fiber-reinforced plastering mortar and a preparation method thereof. The fiber-reinforced plastering mortar is prepared from the following raw materials in parts by weight: 150-200 parts of cement, 150-200 parts of diatomite, 15-20 parts of modified nanometer titania, 0.8-1.2 pars of engineering polypropylene fiber, 6-10 parts of inorganic pigment and 250-300 parts of water. The fiber-reinforced plastering mortar can utilize the catalytic action of a compound photocatalyst to reduce the content of evaporable harmful gases such as formaldehyde gas indoors during the day and utilize the adsorption effect of diatomite to adsorb gaseous pollutants during the night; and in addition, the anti-crack, anti-permeability, anti-freezing and anti-fatigue performance of the plastering mortar is greatly improved; early-crack of the mortar is prevented, the durableness is improved, and the wall body self is well protected to some extent.

Description

technical field [0001] The invention belongs to the field of ready-mixed mortar, and discloses a fiber-reinforced plastering mortar and a preparation method thereof. Background technique [0002] With the rapid development of the market economy and the continuous improvement of people's material living standards, housing construction has maintained a momentum of rapid development. Before moving into a new house, different degrees of decoration are required to create a beautiful and comfortable living environment, which has led to the upsurge of decoration and the rise of modernization of indoor facilities. [0003] On the one hand, as a large number of new building materials and decoration materials enter people's life and production, the renovated rooms always emit a pungent smell. If you stay for a long time, you will experience dizziness, glare, sore throat, and chest tightness. And other adverse reactions, even rash, fever, respiratory tract infection and other symptoms...
