Oil colour of a kind of graphene-containing and preparation method thereof
Technical field
The invention belongs to oil colour field, be specifically related to a kind of oil colour of graphene-containing; The invention still further relates to the preparation method of the oil colour of this graphene-containing.
Background technology
Current pigment mainly includes watercolors, gouache color, oil colour, acrylic paints etc.; The basal component of oil colour the same with other drawing pigment by colorant, pigment extender, vehicle and some auxiliary material as plastotype agent, stablizer, slow dry agent or siccative etc. are formed.The various performances of oil colour can need by using different catalytic agent and subsidiary material to come suitably to be adjusted according to difference.
The quality of oil colour quality can have a huge impact the performance of painting skill, is also one of prerequisite determining paint life-span length.In recent years, along with the development of drawing industry, the requirement of people to oil colour is also more and more higher.The performances such as the tinting strength of oil colour, resistance to luminous power, opacifying power, transparency, oil number, toughness, ridity, plasticity-and levelling property some directly affect the effect of drawing a picture.
After using oil colour to complete works, usual needs dry for a long time, in the process; due to the electrostatic effect on picture; usually can adsorb some dusts or tiny hair, and be infiltrated storage by the oiliness surface permanent of picture, this have impact on the quality of oil painting largely.
In addition, oil colour progressively to high-end field development, domestic and international market total scale reaches multi-million dollar, and this also has higher requirement to the antistatic property of oil colour, ageing resistance, sticking power and resistance to cracking.
Summary of the invention
For deficiency of the prior art, an object of the present invention is to provide a kind of oil colour of graphene-containing, has good glossiness and antistatic property.Two of object of the present invention is to provide the preparation method of the oil colour of this graphene-containing.
The present invention is achieved through the following technical solutions.
An oil colour for graphene-containing, this oil colour comprises following component and weight proportion thereof: refining sunflower seed oil 20 ~ 35 parts; Printing stand linseed oil 2 ~ 5 parts; Pigment toner 5 ~ 20 parts; 15 ~ 35 parts, barium sulfate; Kaolin 5 ~ 10 parts; Graphene 0.5 ~ 5 part; Nano silicon 3 ~ 10 parts; Refining oleum lini 2 ~ 8 parts; Aluminum stearate 0.1 ~ 1.5 part; 0.2 ~ 1.5 part, beeswax; 422 maleficent acid resins 0.5 ~ 2.0 part; BCM mould inhibitor 0.2 ~ 2 part.
Graphene has the microtexture of sheet, and this structure makes electronics can conduct in the two-dimensional space of Graphene, and therefore Graphene has good conductivity, can be considered desirable conductive agent.In size and geometry, carbon black, carbon nanotube and Graphene can regard point, line, surface as abstractively, and they are inevitable different from the conductive contact interface of electrode active material.Obviously, the contact area between Graphene and active substance will significantly be greater than carbon nanotube and carbon black, and therefore for raising electric conductivity, comparatively carbon nanotube and carbon black be advantageously.
The interpolation of Graphene significantly can improve conductivity and the antistatic property of pigment, makes oil not easily attract dust, also can improve the performance index such as the rub resistance ability of pigment, hardness and sticking power.
Nano silicon has physiological inertia, high absorbability, carrier is commonly used in the preparation of sterilant, when nano silicon makes carrier, adsorbable antibacterial ion, reach the object that sterilization is antibacterial, in the present invention, nano silicon coordinates the use of BCM mould inhibitor, and anti-mold effect can be made more lasting, be convenient to the long-term preservation of paintings, especially in the environment of some warm moist.In addition, the specific surface area of nano silicon is large, porosity is high, Active sites is many containing a large amount of hydroxyls and unsaturated residual bond, has good lubrication, can improve feel when drawing a picture.And nano silicon, as the lower-cost filler auxiliary agent of one, has extremely strong uv-absorbing, infrared external reflection characteristic.Show through ultraviolet-visible spectrophotometer test, it to the uv absorption rate within wavelength 400nm up to more than 70%, also more than 70% is reached to the infrared reflectivity beyond wavelength 800nm, therefore, be added with the ageing-resistant performance that nano silicon can significantly improve oil colour in this pigment, the paint longer-term enable is preserved.
The interpolation of 422 maleficent acid resins, can make oil colour fast drying, and dried paintings are hard, bright, not yellowing, alkaline-resisting, water-fast, resistance to gasoline, good stability.
The applicant, on the basis of many experiments, by adjusting component proportion further, drawing preferred component formula, having following component and weight proportion thereof: refining sunflower seed oil 28 ~ 30 parts; Printing stand linseed oil 3.5 ~ 4 parts; Pigment toner 11 ~ 13 parts; 24 ~ 26 parts, barium sulfate; Kaolin 7 ~ 9 parts; Graphene 2 ~ 3 parts; Nano silicon 7 ~ 8 parts; Refining oleum lini 4 ~ 5 parts; Aluminum stearate 0.7 ~ 1 part; 0.7 ~ 1.4 part, beeswax; 422 maleficent acid resins 0.8 ~ 1.5 part; BCM mould inhibitor 1 ~ 1.5 part.
The invention still further relates to a kind of oil colour preparation method of graphene-containing, comprise the following steps: a. gets the beeswax, aluminum stearate and the refining Semen Lini oil that meet composition weight proportioning and carries out blended, heating and melting, obtains freezing oily A; B. get the 422 maleficent acid resins that meet composition weight proportioning and refining Semen Lini oil carries out blended, heating and melting, obtain gloss varnish B; C. getting all the other components meeting weight proportion, together with freezing oily A and gloss varnish B carries out blended, obtaining finished product through grinding.
In step of the present invention, adopt the mode of component raw material melt blending in batches, improve mixed effect, be convenient to the dispersed of raw material.
As preferably, in described step a, the weight ratio of beeswax, aluminum stearate and refining Semen Lini oil is 2:1:2; In described step b, the weight ratio of 422 maleficent acid resins and refining Semen Lini oil is 1:4.
Compared with prior art, the present invention has following beneficial effect: 1) be added with Graphene, has good antistatic property, prevents attract dust, improves the rub resistance ability of oil colour, hardness and sticking power; 2) be added with nano silicon, can improve the antibacterial effect of pigment, and have good uvioresistant ability, can significantly improve the ageing-resistant performance of oil colour, the paint longer-term enable is preserved.
