Description
Technical field
The invention belongs to technical field of finishing materials, and in particular to a kind of lower shrinkage antifouling ceramic tile joint trimming agent.
Background technique
In modern architecture ceramic tile using very universal, including metope, floor, ceiling, fireplace, wall surface and swimming pool etc.
It can be used Deng, indoor and outdoor.Other face bricks include stone face brick other than ceramic tile, compound or artificial stone's face brick also extensive quilt
It uses.Modern Residence considers the aesthetics of facade and uses functional requirement, and majority uses joint sealing material joint filling, to avoid conventional method
The crack infiltration generated at pointed with cement mortar and accumulation of salt in the surface soil phenomenon, while can obtain and the unified facade effect of finishing material.From vision
On, joint trimming agent brings completely new feeling to house fitting-up, the beauty of household will not be influenced because of the gap of ceramic tile, this makes it
It especially receives an acclaim on beautification space, exquisite in texture after joint trimming agent is spread in the painting of this shape, and uniform color is secured, there is very strong decoration
Effect.It can play a very good protection to building material product especially ceramic tile, and joint trimming agent is applied to after the gap of ceramic tile
Swell-shrinking deformation between energy good absorption ground and masonry, extends the service life of facing.
Joint trimming agent is mainly made of polymer and pigment, is a kind of semi-fluid shape liquid, is broadly divided into one-component joint trimming agent, i.e.,
Daily described aqueous joint trimming agent, another kind is two-component joint trimming agent, and finally a is Self-leveling.Three kinds of joint trimming agents have one
Fixed shrinking percentage, therefore secondary joint filling is generally required after constructing, or even will affect the intensity in joint filling face.Existing gap filler simultaneously
Antifouling property is limited, greatly reduces its service life.
Summary of the invention
The present invention provides a kind of lower shrinkage antifouling ceramic tile joint trimming agents, have lower shrinking percentage, while it is dirty to be not easy adherency
Object and droplet have preferable anti-fouling effect.
The technical proposal for solving the technical problem of the invention are as follows:
A kind of lower shrinkage antifouling ceramic tile joint trimming agent is grouped as by following parts by weight group: 30-40 parts of silicone acrylic emulsion, grape

Part, 10-15 parts of pigment and 1-3 parts of defoaming agent, the polyethylene glycol (PEG) oleate the preparation method comprises the following steps: by oleic acid, polyethylene glycol and
SO4 2-/ZrO2Solid super acid catalyst after mixing, reacts at 120~140 DEG C, constantly removes and generates in reaction process
Water stop reaction until reaction solution is in neutrality, after being cooled to room temperature, filtering, filtrate distillation is gone after moisture removal up to poly- second two
Alcohol oleate.
Preferably, the ultraviolet absorber is 2-hydroxy-4-n-octoxybenzophenone, [2- hydroxyl -4- (octyloxy)
Phenyl] phenyl ketone, 2- hydroxyl -4- octyloxybenzophenone or 2- hydroxyl -4- n-octyloxy Benzophenone.
Preferably, the dispersing agent is glyceryl monostearate, zinc stearate or calcium stearate.
Preferably, the defoaming agent is polyoxyethylene polyoxy propyl alcohol amidogen ether, polypropylene glycerol aether, polyoxypropylene polyoxy
Ethylene Glycol ether or dimethyl silicone polymer.
Preferably, the mass ratio of the oleic acid and polyethylene glycol is 1:6~10, the solid super acid catalyst
Quality is the 0.1~0.15% of polyethylene glycol quality.
Preferably, it is characterized in that, the polyethylene glycol average molecular weight is 600,1000 or 2000.
Preferably, the modified Portland the preparation method comprises the following steps: by silicate be added mass concentration be 20% 12
In sodium alkyl benzene sulfonate-aqueous solution, in 70-80 DEG C stirring 30-50 minutes, stirring gives ultrasonic wave added simultaneously, using filter, filters
Cake drying, ground 60 mesh obtain modified Portland.Metal cation in neopelex and silicate occur from
Son exchange assigns silicate branched structure to enter the molecule interlayer of silicate in a manner of molecule intercalation.When the third cream of silicon
When liquid solidifies, in the branch insertion polymer in modified Portland, to form network structure, the receipts of joint trimming agent are reduced
Shrinkage.
Preferably, the silicate and neopelex-aqueous solution mass ratio are 1:20-30.
Modified poly (ethylene glycol) is esterified using oleic acid, obtains branched polymer, the not hydrophilic not oleophylic of polyethylene glycol (PEG) oleate makes
It obtains greasy dirt and droplet is not easy be attached to joint trimming agent surface, assign joint trimming agent excellent anti-pollution.Oleic acid and polyethylene glycol
Mass ratio determine polyethylene glycol degree of esterification, when the additional amount of oleic acid is too low, esterification degree is not high, and gained joint trimming agent still has
Hydrophily；When the additional amount of oleic acid is excessively high, polyethylene glycol is excessively esterified, and lipophilicity increases, the decline of joint trimming agent anti-pollution.
The invention has the benefit that
