Embodiment 1

[0021] Embodiment 1: a kind of preparation method of wallboard adhesive, formula of the present invention:

[0022] Ordinary Portland cement: 8kg

[0023] Methylcellulose (HPMC), viscosity 85000: 8g

[0024] Water: 5kg;

[0025] Preparation: first put 5kg of water into the mixing bucket, then take out 8g of methyl cellulose (HPMC) and pour it into the mixing bucket, stir with a stirrer with a rotation speed of 10~12r / s for 150~180s, until the liquid is When it becomes thick, finally add 8kg of ordinary Portland cement and continue stirring for 150~180s.

Embodiment 2

[0026] The difference between embodiment 2 and embodiment 1 is only: the formula of the present invention is:

[0027] Ordinary Portland cement: 8kg

[0028] Methylcellulose (HPMC), viscosity 85000: 0.8g

[0029] Water: 4.88kg;

Embodiment 3

[0030] The difference between embodiment 3 and embodiment 1 is only: the formula of the present invention is:

[0031] Ordinary Portland cement: 8kg

[0032] Methylcellulose (HPMC), viscosity 85000: 24g

[0033] Water: 5.12kg;

Abstract

The invention discloses wallboard binder and a preparation method thereof. The wallboard binder comprises cellulose ether, water and cement, wherein the weight ratio of the cellulose ether to the water to the cement is (0.1-3):(610-640):1000. The preparation method includes: loading the water into a stirring barrel according to the weight, placing the cellulose ether into the stirring barrel, and stirring with a stirrer for 150-180 seconds until liquid is thick; adding the cement, and stirring with an electric stirrer for 150-180 seconds to obtain the wallboard binder. The wallboard binder and the preparation method thereof have the advantages that the wallboard binder only comprises three components, the cellulose ether and the cement are powdered and do not form granules after mixing, the binder is fine and smooth and lubricating in surface and good in binding performance, the preparation method can replace a tradition method which needs multiple components to jointly prepare the binder, unevenness during binder smearing can be avoided, and manpower cost increasing can be avoided.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a wallboard adhesive and a preparation method thereof, especially suitable for ash-slag concrete wallboards. Background technique [0002] The wall panels of the prefabricated building are matched with the mortise and mortise edges of the concave-convex structure. When installing the wall panels, the top and side edges of the mortise and mortise edges are covered with mortar. , the thickness of the adhesive is not less than 5mm. When the wallboard is erected, use a crowbar to squeeze it into place, correct the verticality and the flatness of the adjacent board surface, and ensure that the seam is tight and straight, and then place it on the top of the wallboard The head is tightened with a wooden wedge, the gap is less than 5mm, the extruded mortar is scraped and filled in time, and the wall is leveled and verticalized with a ruler and a support board. Bonding is one of the key...
