Description
Technical field
The invention discloses a kind of preparation methods of resistance to compression fibrous plaster, belong to building material technical field.
Background technique
Plasterboard mainly has: Thistle board, without Thistle board, decorated gypsum board, gypsum hollow lath, fibrous plaster
Plate, plaster board, locating-point plasterboard etc..Thistle board is using Gypsum slurry as sandwich, and two sides is formed with paper as mask
A kind of light weight board.Thistle board quality is light, intensity is high, prevents fires, is mothproof, easy to process.Common Thistle board is used for
Interior wall, partition wall and furred ceiling.Water-fast Thistle board by fire prevention processing can be used for the biggish room metope of humidity, such as health
Between, kitchen, the tilings such as bathroom, metal plate, plastic cover brick wall liner plate.No Thistle board is exactly a kind of generation of superior performance
Wood plank, using building gypsum plaster as primary raw material, using various fibers as a kind of building panel of reinforcing material.It is after paper
After plasterboard obtains extensive use, another new product succeeded in developing.Since appearance eliminates Protecting Paper, application
Range is also expanded other than whole application ranges of covering paper cream plate, and comprehensive performance is better than Thistle board.Decoration
Plasterboard be using building gypsum as primary raw material, add made of a small amount of fibrous material etc. there are many pattern, floriation plate, such as
Gypsum printing plate, perforation ceiling board, gypsum embossed hung ceiling plate, Paper-faced gyp decorative lamination decoration board etc..It is a kind of novel interior
Ornament materials is suitable for medium-to-high grade decoration, has the characteristics that lightweight, fire prevention, moisture-proof, easy processing, installation are simple.It is especially novel
Resin imitates type veneering water-proofing plasterboard plate face coated with resin, and facing imitates type decorative pattern, and tone pattern is true to nature, novel generous, plate
Intensity height, anti-pollution, easy cleaning, can be used for decorated wall surface, do skirting and skirting board etc., be to replace lithotome and terrazzo
Ideal material.Gypsum hollow lath is using building gypsum as primary raw material, after adding appropriate light filler or fibrous material
A kind of hollow plate being process.This plate does not have to paper and binder, and keel are not had to when installation, is development than faster one
Kind light weight board.It is mainly used for interior wall and partition wall.
Fibrous plaster is and to add appropriate fibre reinforced materials using building gypsum as primary raw material and be made.This plate
Bending strength be higher than Thistle board, can be used for interior wall and partition wall, can also replace timber make furniture.Fibrous plaster is very
It is easy to carry, it is hardly damaged.Since vertical transverse strength is identical, therefore vertical and horizontal can install.The installation of fibrous plaster and
It is fixed, in addition to being fixed as Thistle board with screw, wire nail, make construction more fast and conveniently.General Paper-faced gyp
The installation system of plate is used equally for fibrous plaster.The finish of fibrous plaster can use all kinds of wallpapers, wall paper, all kinds of coating and each
Kind wall brick etc..It can be made into the upper surface of plate bright and clean smooth or machined at various pattern forms.Or it is printed as various
Decorative pattern is embossing at rough pattern pattern.But fibrous plaster compressive property is bad, therefore, to cebollite
The research of cream plate mechanical property is particularly significant.
Summary of the invention
The present invention solves the technical problem of: for the bad problem of conventional gypsum plate compressive property, provide one
The preparation method of kind resistance to compression fibrous plaster.
In order to solve the above-mentioned technical problem, the technical scheme adopted by the invention is that:
(1) according to parts by weight, by 10~20 parts of coir fibres, 2~3 parts of biogas slurries, 0.3~0.5 portion of sucrose, 20~30 parts of water are mixed
Close fermentation, freezing, ball milling, sieving, steam explosion, pretreatment mixing slurry；
(2) according to parts by weight, by 10~20 parts of quick limes, 30~60 parts of pretreatment mixing slurries, 3~5 parts of starch milks are mixed, quiet
It sets, obtains mixing lime white；
(3) according to parts by weight, by 30~40 parts of pretreated ardealites, 40~60 parts of building gypsum plasters, 3~5 parts of phosphatide, 3~5
The modified additive of part, 2~3 parts of modified sodium alginate liquid, 20~30 parts of mixing lime whites, 40~60 parts of water are stirred, injection molding,
Cold pressing solidifies, and demoulding obtains slab；
(4) steel slab surface is sprayed into dopamine solution, it is dry to get resistance to compression fibrous plaster.
The process for preparation of step (3) described starch milk are as follows: stir starch and water 1:10~1:20 constant temperature in mass ratio mixed
It closes, is subsequently added into 0.01~0.02 times of starch quality of amylase, constant temperature is stirred, and the enzyme deactivation that heats up is to get starch milk.
The preparation process of step (3) described pretreated ardealite are as follows: be in mass ratio 1:40~1:60 by ardealite and nothing
Water-ethanol mixing and ball milling obtains ball milling material, and is in mass ratio that 80:1~100:1 Hybrid Heating is anti-with sulfuric acid by gained ball milling material
It should be to get pretreated ardealite.
Step (3) phosphatide is milk phosphatide, any one in yolk phospholipid or soybean lecithin.
Step (3) the modified additive are as follows: glass bead is mixed with sodium hydroxide solution 1:3~1:5 in mass ratio,
Filtering, obtains pretreatment glass bead, and pretreatment glass bead is mixed with epoxy resin 1:5~1:7 in mass ratio, is impregnated, mistake
Filter, obtains filter cake, filter cake is mixed with isocyanates 1:3~1:5 in mass ratio, filters, obtains pretreatment modification glass bead, will be pre-
Modified vitrification micro-bead and paraffin 1:5~1:6 mixed grinding in mass ratio are handled, modified additive is obtained.
The preparation process of step (3) the modified sodium alginate liquid are as follows: by sodium alginate and water 1:50~1 in mass ratio:
100 mixing, after standing swelling, heating stirring dissolution is subsequently added into 0.01~0.02 times of sodium alginate quality of sodium metaperiodate, permanent
Temperature is stirred to react to get modified sodium alginate liquid.
Step (4) the cold pressing condition are as follows: pressure is 8~15MPa.
The beneficial effects of the present invention are:
Modified sodium alginate liquid and phosphatide provided by the invention, firstly, during the preparation process, by adding phosphatide, on the one hand, phosphorus
Rouge occurs slowly to hydrolyze under alkaline system, calcium binding in hydrolysate and system, thus by five oxidations in ardealite
Two phosphorus are converted into the calcium hydroxy phosphate for being conducive to panel strength, and system intensity is made to effectively improve, on the other hand, after degradation
Coir fibre activity improve, can effectively be combined with hydroxyapatite newly-generated in system, then after being mixed with quick lime, in alkali
Property under the conditions of further rot, residue is difficult to the careless muscle portion degraded point, after being added in plasterboard system, as reinforcement, into
One step improves the mechanical strength of plasterboard, simultaneously as the hydroxyl on sodium alginate strand is oxidized to aldehyde radical, due to careless muscle
Surface is through excessive erosion, so that the activity hydroxy on surface is exposed, the aldehyde radical on modified sodium alginate strand can be with careless muscle
Aldol reaction occurs for the hydroxyl of part of the surface, so that interface binding power gets a promotion between careless muscle and modified sodium alginate, makes
While obtaining the formation densification three-dimensional network in system, containing the careless muscle with excellent toughness in three-dimensional network, so that body
The compression strength of system gets a promotion.
