Description
Technical field
The invention belongs to technical field of composite materials, are related to a kind of high performance resin mortar suitable for FRPM pipe clamp layer of sand
And preparation method thereof.
Background technique
As a kind of long distance water transfer tubing, in China, many water supply and sewage work are had been obtained answers FRPM pipe extensively at present
With.FRPM pipe has the characteristics that high-strength light, corrosion-resistant, hydraulic characteristic(s) is excellent and service life is long, according to selection resin base
The difference of body type, FRPM manage the demand for being also able to satisfy different water supply and sewage work, have good adaptability.
Resin mortar is the main material for promoting FRPM pipe stiffness, and the bending property of resin mortar has very pipe stiffness
Important influence.At present in FRPM pipe industry, the resin mortar bending elastic modulus of China's prior art manufacture is about 6-
8GPa, resin content are about 16%-20%；The resin mortar bending elastic modulus of overseas enterprise's manufacture is about 12.5GPa, resin
Content is reduced to 11.5%.However, even if main production cost still collects in FRPM pipe made by technique leading in the world
In in resin sand pulp layer.Therefore, the material property of resin mortar is improved, reducing production cost is current FRPM pipe and relevant tube
The important topic that road industry development is faced.
Summary of the invention
The high performance resin mortar and preparation method thereof that the purpose of the present invention is to provide a kind of applied to FRPM pipe uses
The resin mortar amount of resin of this method manufacture is lower than the average level of country 18%-20%, and product mechanical property is excellent.
In order to achieve the above objectives, as follows using technical solution：
A kind of resin mortar applied to FRPM pipe, including resin and quartz sand, by mass percentage for：
Resin 11%-14%, quartz sand 86%-89%；
Wherein, the composition of resin is as follows by mass percentage：
Curing agent：Methyl ethyl ketone peroxide 0.7%-0.9%；
Promotor：Cobalt iso-octoate/styrene 0.7%-0.9%；
Resin additive：Polyacrylate 0.3-0.6%；
Remaining is adjacent benzene or isophthalic vinyl ester resin.
According to the above scheme, the promotor is cobalt iso-octoate/styrene mixture, wherein the mass percent of styrene
80%-90%.
According to the above scheme, the resin viscosity value should be lower than 300mPas.
According to the above scheme, the quartz sand is gradation quartz sand, and each gradation quartz sand accounts for the percentage of quartz sand gross mass
For：
Less than 70 mesh：32%-41%
1-3mm：40%-49%
3-5mm：12%-15%
5-8mm：4%-8%.
The preparation method of the above-mentioned resin mortar applied to FRPM pipe, includes the following steps：
1) quartz sand is cleaned, is dried, the quartz sand by partial size greater than 1mm mixes；
2) quartz sand less than 70 mesh is added in resin, forms resin-bonded mastic after mixing；
3) above-mentioned mixed quartz sand is added in resin-bonded mastic and is sufficiently mixed, sufficiently vibrated to obtain and be managed applied to FRPM
Resin mortar.
The beneficial effects of the invention are as follows：
The present invention provides a kind of technical solution with application and preparation in the high performance resin mortar of FRPM pipe, amount of resin
Lower than the average level of domestic 18%-20%, resin mortar cost is effectively controlled.
High performance resin mortar of the present invention applied to FRPM pipe, bending elastic modulus obviously exceed domestic current
The average level of 6-8GPa.
Specific embodiment
For a better understanding of the present invention, below with reference to the embodiment content that the present invention is furture elucidated, but it is of the invention
Content is not limited to the following examples.
The resin mortar preparation process that the present invention is applied to FRPM pipe is as follows：
(1) preparation of quartz sand
The quartz sand of different-grain diameter is cleaned and removes impurity；Quartz sand through over cleaning is placed in thermostatic drying chamber
4~6 hours, cavity temperature was set as 120 DEG C, and quartz sand water content should be not more than 0.2% after drying.After weighing drying by gradation
Each partial size quartz sand；Each partial size quartz sand that will be greater than 1mm is uniformly mixed, and is stood until quartz sand is cooled to room temperature.
(2) preparation of resin-bonded mastic
Resin is weighed in proportion, sequentially adds resin additive, promotor, and curing agent is added after stirring 2-4min；Holding is stirred
It mixes, the fine quartz sand less than 70 mesh is slowly added into resin, forms resin-bonded mastic after mixing；To ensure resin mortar
Smooth preparation, resin-bonded mastic must have certain mobility.The ratio of resin and fine quartz sand is big in the resin-bonded mastic
About 1:2.6 to 1:Between 3.3.
(3) preparation of resin mortar
By mix be greater than 1mm quartz sand be added in resin-bonded mastic in batches, this process should whole process be kept stirring；
Quartz sand should be sufficiently mixed with resin-bonded mastic, it is ensured that quartz sand particle is wrapped up by resin-bonded mastic；Resin mortar after mixing
It should sufficiently be vibrated, ensure that resin mortar is closely knit.
(4) it conserves
It is placed in and stands maintenance at room temperature, until resin mortar is fully cured；23 DEG C can be placed in when conditions permit, 48% humidity
In the environment of 4-5 days.
By taking adjacent styrene base ester resin makes resin mortar as an example, each embodiment material fiting ratio and performance data such as table 1-
Shown in 4.
Each embodiment material fiting ratio of table 1
2 each embodiment resin mortar compressive property test result (5 DEG C of environment temperature) of table
3 each embodiment resin mortar bending property test result (5 DEG C of environment temperature) of table
Example 3 is tested under 25 DEG C of environment, and measuring average bending elastic modulus is 17.5GPa.
Each embodiment resin mortar density of table 4
From comparing result as it can be seen that influence of the different quartz sand graduations to resin mortar finished product has in terms of following two：
(1) amount of resin
As polynary grading of aggregates system, mixed its bulk density of gradation quartz sand and porosity are closely related, heap
Porosity is smaller between the high gradation quartz sand particle of product density, and the resin-bonded mastic dosage as filling is also less, and then resin
Dosage is also reduced.
(2) mechanical property
More closely knit inside the high resin mortar of density, defect is few, therefore mechanical property is more excellent.
The present invention is not limited to above-mentioned specific embodiment in an implementation, is also not necessarily limited to FRPM pipe application.It is being appropriately modified
Under can be applied to various be suitble to other field of the invention.Therefore without departing substantially from universal involved in claims
Under, the present invention is not limited to embodiments.
