3results about How to "Excellent tensile modulus" patented technology

The invention relates to a ketoxime-terminated siloxane halogen-free environment-friendly flame-retardant adhesive, which belongs to the technical field of adhesive preparation and specifically comprises the following raw materials in parts by weight: hydroxyl silicone oil, dimethyl silicone oil, a flame-retardant fire retardant, fumed silica, a cross-linking agent, a coupling agent, a chain extender, an organic tin catalyst and an end-capping catalyst. The modified ammonium polyphosphate is self-made, the compatibility of the modified ammonium polyphosphate and the basic polymer hydroxyl silicone oil is improved, the additive amount of the modified ammonium polyphosphate in a system is increased, and the flame-retardant and fireproof performance of the system is improved to a certain extent; on the basis, the self-made modified ammonium polyphosphate and the cage-shaped phosphate melamine salt are compounded to form the flame-retardant fireproof agent, and the flame-retardant fireproof agent is added into the preparation of the flame-retardant adhesive, so that the flame-retardant adhesive finished product has excellent flame-retardant and fireproof performance. Meanwhile, the flame-retardant adhesive finished product prepared according to the formula disclosed by the invention also has excellent tensile modulus and cohesiveness.

This invention provides an aluminum-silicon carbide composite material, its preparation method, and its application. The aluminum-silicon carbide composite material comprises alternating layers of silicon carbide and aluminum material; the number of aluminum material layers is greater than the number of silicon carbide layers; the thickness of the silicon carbide layers is 5 μm to 0.5 mm, and the thickness of the aluminum material layers is 1 μm to 0.15 mm. This invention can reduce the thickness of the aluminum-silicon carbide composite material while simultaneously improving its mechanical strength.

The present invention pertains to a regenerated polyamide resin composition obtained by melt-kneading a polyamide resin (a) or a polyamide resin composition (A) containing a polyamide resin (a) as a main component, a polyamide-based resin waste (B), and a fibrous reinforcing filler (C), the polyamide resin waste (B) contains a polyamide resin (b1) and a thermoplastic resin (b2) other than the polyamide resin, and the content of the polyamide resin (b1) is 11.0 parts by mass or more when the sum of the polyamide resin (a) and the polyamide resin (b1) is 100 parts by mass. The content of the thermoplastic resin (b2) other than the polyamide resin is 0.13 parts by mass or more when the sum of the polyamide resin (a) and the polyamide resin (b1) is taken as 100 parts by mass, and the content of the thermoplastic resin (b2) other than the polyamide resin is 0.13 parts by mass or more in 100% by mass of the regenerated polyamide resin composition. The polyamide resin composition contains 0-80.0 mass% of the polyamide resin (a) or a polyamide resin composition (A) containing the polyamide resin (a) as a main component and 5.0-70.0 mass% of the fibrous reinforcing filler (C). The regenerated polyamide resin composition according to the present invention is capable of contributing to SDGs (Sodium Dodecyl Goals), which is a sustainable development target.
