Problems solved by technology

This type of solution has the disadvantage that the mechanical properties of the material deteriorate compared to compositions without additives added to the polymer to obtain higher conductivity due to the antistatic additive from maleimide The polymerization of is different from the polymerization of reactive solvents usually used in unsaturated polyester resins and epoxy vinyl ester resins
These solutions have two disadvantages: mechanical properties are lost during the polymerization of the thermosetting resin due to the carbon source material acting as a scavenger of free radicals
These solutions lead to another disadvantage: due to the large size of the added solids, in order to reduce the resistance, a large amount of solids needs to be added to the final material
Further, the high demand for conductive solids significantly changes the final properties of the product obtained and, since said conductive solids are visible, significantly limits their coloring possibilities

Embodiment 1

[0081] Salt prepared by encapsulation with sodium aluminosilicate precipitation (95%) (R 4 )N,N,N-trialkyl-alkyl-alcohol-ammonium, where R 1 , R 2 , R 3 is CH 3 , n=2 and OR 4 is OH and the anion is chloride (choline chloride) (5%).

[0082] Use 950 g sodium aluminosilicate, preferably it should have composition 10-14.5 (SiO 2 ), 0.5-1.5 (Al 2 o 3 ), 0.5-2 (Na 2 O), and a surface BET of 50 to 90m 2 / g, for this example we use a BET of 60m obtained by precipitation 2 / g of 14.5 (SiO 2 ) Al 2 o 3 1.4 (Na 2 O) fine powder. Add 50 g of salt (choline chloride) powder. Encapsulation was performed by mixing in a high speed rotary mixer at 2500 rpm for 10 minutes.

Embodiment 2

[0084] Preparation as described in Example 1, wherein the ratio is 10%-90%.

[0085] The preparation starts with a BET of 60m obtained from precipitation 2 / g of 900g sodium aluminosilicate 14.5 (SiO 2 ) Al 2 o 3 1.4 (Na 2 O) fine powder. Add 100 g of choline chloride powder. Encapsulation was performed by mixing in a high speed rotary mixer at 2500 rpm for 10 minutes.

Embodiment 3

[0087] Preparation as described in Example 1, wherein the ratio is 15%-85%.

[0088] The preparation starts with a BET of 60m obtained from precipitation 2 / g of 850g sodium aluminosilicate 14.5 (SiO 2 ) Al 2 o 3 1.4 (Na 2 O) fine powder. Add 150 g of choline chloride powder. Encapsulation was performed by mixing in a high speed rotary mixer at 2500 rpm for 10 minutes.

Abstract

The invention relates to a novel formulation based on two components, which, when added to items produced with epoxy vinyl ester or unsaturated polyester resin, provides same with electric charge dissipation and / or antistatic characteristics, maintaining the mechanical characteristics thereof and the possibility of dyeing the material in all of the possible colour ranges. The formulation has a first component which is an active substance which is an ionic salt that allows ion mobility, the cation being a compound based on the (R4)N,N,N-trialkyl-alkyl-ol-ammonium species, as it is or derivatised on the OH group, and a system that supports said active substance. This additive or formulation added to epoxy vinyl ester or unsaturated polyester resin can be used in the production of agglomerated stone, gel coat, sheet moulding composite or bulk moulding composite.

Description

technical field [0001] The present invention relates to a new formulation and method for its manufacture, which is added to articles made of unsaturated polyester resins or epoxy vinyl ester resins to provide these articles with antistatic and / or charge dissipation, retention Its mechanical properties and the possibility to color the material in all possible color ranges. Background technique [0002] Traditionally, articles made of unsaturated polyesters and epoxy vinyl esters have exhibited high surface resistance and mass transfer resistance (resistivity values ​​exceeding 10 at 20°C) 12 Ω˙m), there is a problem of electrostatic charge accumulation on its surface. The accumulation of charge can have harmful effects such as discharges to human bodies, materials, fuels and electronic systems. When these materials are subjected to friction, for example by the passage of a person or even the action of wind containing dust or sand grains, a build-up of electric charge occurs...
